Scaffolding for Multiplication

“Instructional scaffolding is a learning process designed to promote a deeper level of learning. Scaffolding is the support given during the learning process which is tailored to the needs of the student with the intention of helping the student achieve his/her learning goals” (Sawyer, 2006).

Pre-multiplication Knowledge – Multiplication Whole Numbers

Sample Debrief Questions Might Include:• On the first page, what did you notice about the

answers to your problems? • Discuss the relationship between repeated

addition and the unit form 2 groups of three or 3 groups of two, depending on the drawing.

• Discuss the relationship between repeated addition, unit form, and the multiplication sentence 3 × 2 = 6.

• Review the new vocabulary presented in the lesson: equal groups, multiplication, and multiply.

Page 41: 3-5 Standards and Support Training Office of Standards and Learning Mary L. Ruzga mruzga@ed.sc.gov Summer 2015

Pre-multiplication Knowledge – Multiplication Whole Numbers

Step 4: Introduce array as a more efficient method to see that groups are equal; identify rows and columns, make arrays and link to multiplication.

While the term array was introduced in 2nd grade (2.ATO.4) it was with repeated addition and must now be treated as new vocabulary because we are linking it to multiplication.

Page 42: 3-5 Standards and Support Training Office of Standards and Learning Mary L. Ruzga mruzga@ed.sc.gov Summer 2015

Pre-multiplication Knowledge – Multiplication Whole Numbers

We can count and add, OR if the size of each group is the same (equal) we can use repeated addition or multiplication to find the total number of objects in groups like this.

• What is the symbol for multiplication?• Write a repeated addition and a multiplication

equation for this picture. • Share with your partner.

This organized picture is called an array – like you used with repeated addition in 2nd grade.

Arrays are made of rows and columns. Rows tell how many in a group, columns tell how many groups. Use the 3 x 10 dot arrangement to trace and show rows/columns.

Pre-multiplication Knowledge – Multiplication Whole Numbers

Now that students have some understanding of the meaning of multiplication and the link to repeated addition, multiplication can be introduced in story problems, as a way to learn – not just facts to be memorized.

Page 50: 3-5 Standards and Support Training Office of Standards and Learning Mary L. Ruzga mruzga@ed.sc.gov Summer 2015

Multiplication - Whole Numbers

By introducing multiplication in this manner, students not only know the meaning of multiplication but can use repeated addition as a strategy to solve single digit by single digit problems, if they don’t know the multiplication fact. Time should be spent ensuring that students have a firm understanding of the 1, 2, 3, 4, 5 facts before moving to other facts. - why?

• Use grid paper to again draw the same whole number model/array you used for 14 x 23. Label it this time with the decimal factors 1.4 x 2.3. Clearly label the whole number and decimal portions of the factors. (It is cm grid paper so

you can lay your model on grid paper and trace around it. Be sure to trace/outline the wholes, ten strips and hundreds cubes.)

Then compare with your neighbor and discuss how the whole number and the decimal models relate. Save the base ten block model.

What is 16 x 12? What is tenths x tenths?What is 1.6 x 1.2 =?

• Use grid paper to draw the same model (array) you used for whole number 16 x 12. Label it this time with the decimal factors 1.6 x 1.2

• Clearly label the whole number and decimal portions of the factors. Then compare with your neighbor. How do the whole number and decimal models compare?

Multi-digit multiplication – whole numbers and decimals. . .

Strategies for making decimal arrays:• Think whole numbers• Think size of group and number of groupso Think size of group and form one group.o Think how many groups and make that

many groups of the size needed.o Arrange the groups in an array and trade to

use the fewest number of pieces.

The tendency in the US is to have children solve a lot of problems in a class period and focus on the correct answer rather than focusing in-depth on one or two well-chosen problems at a time, the relationship between the structures of the problems and the variety of approaches to the solutions.
