Rationale for the use of problem pictures in the classroom

The implementation of the AusVELS curriculum will occur next year in primary schools across Victoria, with the aim of encouraging teachers to ‘help students become self-motivated, confident learners through inquiry and active participation in challenging and engaging experiences’ (Victorian Curriculum and Assessment Authority, 2012, p.2). The use of effective open-ended problems provides an approach to the teaching and learning of mathematics that addresses this aim, as such tasks provide opportunities for engaging all students in successful learning experiences, while also allowing students to approach the task at varying levels and in varying ways (Sullivan, Mousley & Zevenbergen, 2005). Open-ended problems also have added advantages of giving students ‘opportunities to investigate the problem context, make decisions, generalise, seek connections, and identify alternatives’ (Sullivan, Mousley & Zevenbergen, 2005, p.107).

A problem picture is defined as ‘a photograph of an object, scene or activity that is accompanied by one or more open-ended mathematical word problems based on the context of the photo’ (Bragg & Nicol, 2011, p.4). Using open-ended problem pictures provides opportunities for teachers to ‘pose new kinds of problems: those that are open-ended and grounded in images of real-life activities’ (Bragg & Nicol, 2008, p.202). This creates relevance for students as they develop an understanding of the connection between mathematics in the classroom and in everyday, real world contexts (Bragg & Nicol, 2011). Through connecting mathematical concepts to student’s worlds and experiences, the likelihood of students remembering and applying concepts in future situations is increased (Carpenter, Frank & Levi, 2003). Another benefit stated by Phillips (2012) includes the ability for problem pictures to challenge students at a range of levels. Furthermore, Bragg & Nicol (2011) assert that problem pictures ‘can ultimately enhance an educator’s ability to connect with mathematics in ways that open possibilities for seeing maths differently’ (p.3). Using open-ended problem pictures in the classroom provides teachers with a strategy for achieving the aforementioned aim of the AusVELS curriculum, while also developing students’ awareness of mathematics around them (Bragg & Nicol, 2011).

Problem Picture 1 - Questions

Question 1: Prep Lower PrimaryChoose donuts that are alike to create groups of donuts. Compare the groups of donuts - how are these donuts similar? How are they different? Which groups have more and which groups have less?

Answers to Question 1In responding to this question, students could cut out the donuts in this photo and order them into groups of similar objects.1) Pink, brown, yellow and no icing:

Pink Icing Brown Icing Yellow Icing No Icing

The donuts in these groups are the same because they all have the same colour icingThe donuts in these groups are not the same because they are different sizes and shapes.There are more donuts without icing than with pink icingThere are less donuts with brown icing than yellow icing

2) Big donuts and small donuts:Big donuts Small donuts

The donuts in these groups are the same because they are all the same sizeThe donuts in these groups are not the same because they have different colours of icingThere are more big donuts than small donutsThere are more small donuts without icing than donuts with icing

3) Donuts with holes and donuts without holes:Donuts

without holes in the centre

Donuts with holes in the centre

The donuts in these groups are the same because they are all the same shapeThe donuts in these groups are not the same because they are different sizesThere are more donuts without holes than donuts with holesThere are less iced donuts without holes than the iced donuts with holes

Report of Trialling Problem Picture 1 Question 2 Child’s pseudonym, age and grade level: Child A, 9 years of age, Grade 3

Original Question: When trialling this problem picture, the initial wording for this Level 3 question was: ‘Create a display that shows the information in this photo by organising the donuts into categories’.

Child’s response to the question:

Initial attempt at putting objects into categories

(Sp = sprinkles)

Organising donuts into categories

Data Display - table

Reflection on child’s response:As indicated by this student’s responses, some initial confusion was evident in both how to organise the objects into categories, and how to best present the data located within this photo. However, once I began discussing the question with this student, and explicitly addressed the fact that the purpose of organising the donuts into categories was to assist in making sense of the data, the process became clearer for the student and she was then able to develop a way of efficiently recording and presenting that data both in the form of diagrams, and as a display in the form of a table. Given the context where this question was trialled in an informal setting without any prior discussion or information regarding the mathematical concepts addressed in this question, it is hard to determine whether this initial difficulty is indicative of a weakness in this student’s ability to interpret the photo and collect the relevant data. Sullivan, Mousley and Zevenbergen (2005) state the importance of teachers explicitly explaining the processes in the classroom to their student, including ‘the mathematical focus and purpose of the task’ (p.107). Once this was made explicit to the student, and the wording of my question was adjusted, the student was able to complete the task independently.

In referring to the student’s mathematical understanding, this question highlighted significant strengths in organising objects into categories, and an ability to extend this organising by developing the sub-categories of small and large. She was also competent at finding an effective way to record the data from the photo, and at displaying that data

she had collected in the form of a table. As such, the mathematical intent of the question was addressed with reference to the content strand stating that students at this level ‘collect data, organise into categories and create displays’ (Victorian Curriculum and Assessment Authority, 2012, p.23), all of which are demonstrated in this student’s responses. The proficiency strand at Level 3 states that ‘problem solving includes formulating and modelling authentic situations involving planning methods of data collection and representation’ (VCAA, 2012, p.21), which is again demonstrated in this student’s responses.

Bragg & Nicol (2011) suggest that the process of developing open-ended problem photos is cyclical, with pre-service teachers rethinking the problem posed as they are devising a question. In this situation, the wording of this problem was rethought as a result of reflecting on this trialling process, and the final version of this question has been modified to:

‘Collect information about the donuts in this photo and organise the donuts into categories. Create a data display that presents your information’.

Putting steps into the question by ordering the words differently seemed to assist the student in working out a method for responding to this question. As Sullivan, Mousley and Zevenberg (2005) point out, it would be necessary for the mathematic terminology to also be explicitly addressed, with reference in this question to the meanings of terms such as ‘data display’.

Report of Trialling Problem Picture 2 Question 2 Child’s pseudonym, age and grade level: Child B, 10 years of age, Grade 4

Original Question: The original wording trialled for this problem picture for Level 4 question was:

‘Outline the 2-dimensional shapes you can see in this photo. Can you combine 2 or more of these shapes to create new shapes? Can you split these shapes made up of more than one shape to create new shapes?’


2D shapes outlined in black texta and blue pen

Summary of shapes found, and examples of combining and splitting shapes

Reflection on child’s response:This grade 4 student’s final responses to this problem picture were as expected, however during the process of answering this question, the student required scaffolding to complete components of the question. This student chose to work through each sentence of this question sequentially, beginning with the identification of 2-dimensional shapes. The process from there involved the supporting the student and working with her through each of these identified shapes, assessing if each one was an example of an individual shape or a composite shape. Sullivan, Mousley and Zevenbergen (2005) state that a key aspect of developing effective open-ended tasks is providing ‘prompts to support students who are experiencing difficulty’ (p.105). With this additional support in processing the problem, the student was then able to combine individual adjoining shapes to create new shapes. This student was also able to split the composite shapes by identifying the familiar shapes she saw within the original shape.

This trialling process demonstrated strengths in the student’s understanding and ability to identify and describe two-dimensional shapes, and an apparent difficulty in understanding the way that shapes could combine or split to create new shapes. It was an interesting concept for this student to consider the occurrence of shapes in everyday settings, and to use this photo as a tool for seeing ways that two or more shapes could join or separate to create new shapes. This may be a result of a lack of familiarity with questions framed in this way, as she was able to name and describe each of the two dimensional shapes she found during this task. She required assistance with changing the lens that she was looking through when honing in on part of a composite shape, and when broadening the focus to include surrounding shapes that could combine together. The student’s initial response to this problem picture may be key, as her comment of ‘I hate doing shapes in maths’ is telling. The problem with this question may be due to the issue

raised by Sullivan (2010), whereby students may respond negatively to a task due to the context being unfamiliar and/or uninteresting for the student.

The process described above indicates that the question addressed some of the mathematical intent of the question, however the wording of the problem was changed to include directions to describe the shapes found. The content strand states that students at this level ‘compare and describe two dimensional shapes that result from combining and splitting common shapes’ (VCAA, p.27).

At the conclusion of this trialling process, I decided to reword the question to also include the direction for students to use different colours for each aspect of the question, to assist in the process of highlighting the different shapes, and the ways that they combine and split, in a more effective way than the response given during this trial. The wording of the question was modified to instead read:

‘Outline the 2-dimensional shapes you can see in this photo. Can you combine 2 or more of these shapes to create new shapes? Can you split shapes that are made up of more than one shape to create new shapes? Name and describe these new shapes, and outline them in different colours.’

Report of Trialling Problem Picture 3 Question 2 Child’s pseudonym, age and grade level: Child C, 9 years of age, Grade 3

Original Question: The initial wording for the trial of this Grade 3 level problem picture was:

‘If I was wanting to park here for three hours, how much would I have to pay? What are some of the combinations of coins I could use if I had to use at least three different coins?’


Reflection on child’s response:In responding to this question, this student demonstrated strengths in both developing multiple ways of representing money in the forms of drawing the coins required to respond to the question, and in writing a list of the

coins that she chose to use. The student also demonstrated strengths in performing calculations using repeated addition to ensure that the total of the coins matched the amount that the question required, and in coming up with a number of solutions, working from straightforward combinations to more complicated arrangements as her confidence with the task grew. As such, the student responded to the problem picture in the way that I had initially intended.

Sullivan (2005) suggests using prompts to support students in responding to open-ended tasks, where ‘the choice of appropriate enabling prompts is based on factors that may contribute to the complexity of a task’ (p.12). One such factor discussed in this article is ‘the degree of abstraction or visualisation required’ (Sullivan, 2005, p.12). I was concerned with this problem pictures that students may have difficulties with the visualisation of coins that the task required. In anticipating this as a factor, I provided the student with a variety of coins to act as concrete materials as a means of giving the student access to exploring and completing the question (Sullivan, 2005). This student was able to work independently without requiring the coins as concrete materials to support her in answering this question. This demonstrated a further strength in her ability to process the given information and in problem solving through exploring a different approach to the task that enabled her to engage with the question.

While the Level 3 content strand stipulates that students at this level ‘represent money values in multiple ways and count the change required for simple transactions to the nearest five cents’ (VCAA, 2012, p.22), the information embedded in the photo specified different requirements, where 10 cents was the smallest coin that could be used to purchase a ticket. As a result, this question did address the mathematical intent of the question despite this task not requiring the inclusion of five cent coins. However, this element added to the interactive nature of this photo, where ‘the photo was essential to complete the problem’ (Bragg & Nicol, 2011, p.7).

In reflecting on the trialling process of this photo, the wording of the question was altered as a means of clarifying the requirements of the question, while still ensuring that the problem was open-ended:

‘If I was wanting to park here for three hours, how much would I have to pay? What combinations of coins could I use if I had to use at least three different coins?’

Overall Conclusion

Through the process of undertaking this Problem Picture task, I have developed a new appreciation for the occurrence of mathematics in everyday items, locations and situations through changing the perspective in which I view the world around me as being full of potential for authentic settings to cultivate mathematical understandings and thinking. The simple task of having my digital camera with me when on an expedition in the city provided me with many photos in which a variety of mathematical concepts could be developed and explored. After this step, I followed the second approach outlined by Bragg & Nicol (2011) as starting with the photo, then posing problems based on relevant curriculum content and proficiency strands for each level. Trialling these problem pictures with both students and peers allowed me to clarify my wordings for the questions posed to ensure that the mathematical intent was consistent with the set task.

The effective use of open-ended questions as presented by Sullivan (2010) and the specific approach of open-ended problem pictures discussed by Bragg & Nicol (2011) have changed my perspectives on a new approach to catering for diversity in the classroom and in the differentiation of tasks to allow all students to engage in the same task, with the use prompts as means of scaffolding to support students experiencing difficulties and extend students who complete the initial task readily. Through the course of this task, open-ended problem pictures have provided rich opportunities for exploring mathematics for myself, the students involved in the trialling, and my peers who I tested the questions on. The experience of completing these problems proved to be engaging, enjoyable and provided challenges, as well as connecting the world around me to maths. This is invariably a fundamental connection that these problem pictures assisted in developing.

The findings of Bragg & Nicol (2008) state that the process of pre-service teachers designing problem pictures ‘prompted a shift in their understanding of pedagogical approaches and ways in which they viewed mathematics’ (p.206-207). Bragg & Nicol (2011) also state that problem pictures have the potential for ‘broadening preservice teachers’ pedagogical repertoire to incorporate maths in the environment’ (p.5). This has certainly proved to be true for myself, where I now feel confident in employing this as a pedagogical approach that provides students with opportunities to see and understand the connections between mathematics in the classroom context and in the real-world environment (Bragg & Nicol, 2011). This task has also expanded my understanding of what is possible in teaching mathematics and developing meaningful learning experiences for all students (Bragg & Nicol, 2009).
