Analyzing Word Problems (Word Clues and the Operation to Use)
I. Learning Objectives
Cognitive: Analyze word problems involving addition of whole numbers by telling the word clues and the operation to be used
Psychomotor: Tell what the word clues and the operation to be used in the problem
Affective: Show love and care for animals
II. Learning Content
Skill: Analyzing problems by telling the word clues and the operation to be used
Reference: BEC/PELC I B4. 1.1.3 & 1.4
Materials: moving pictures of 2 boys (somewhat like puppets with sticks but with background pictures of farm chickens and ducks), flash card of addition
Value: Love and care for animals
III. Learning Experiences
A. Preparatory Activities
1. Drill
Addition facts on flash cards
2. Review
Introduce the game: “Little Investigations”
Divide the pupils into two groups. The first group will draw and the second group will write the given facts of the word problem on the board as if they are investigating and gathering facts to solve the problem.
3. Motivation
Sing a song about animals.
“If I were a butterfly,
I thank you Lord for giving me wings.And if were a robin in a tree,I thank you Lord that I could sing.And if I were a fish in the sea,I wiggle my tail and wiggle with glee,But I just thank you Father for making me, Me.”
*Valuing: What are the animals mentioned in the song?Do you like animals? Do you have pets at home?What do you do totake care of your pet?Let us find out in our story who else loves animals very much.
B. Developmental Activities
1. Presentation
a. Present the word problem with the aid of moving pictures. Have two pupils move the pictures while telling the story problem.
Every summer vacation, Bentong and Bayani visit their Lolo's farm. They enjoy playing with farm animals. They also feed the animals. One day, Bentong fed 20 chickens while Bayani fed 30 ducks. How many animals did they feed in all?- Who has a farm?- Who visits the farm every summer vacation- What do they enjoy doing in the farm?- Are the two children kind to animals?- Why do you say so? Are you also kind to the animals? In what way?- What is asked in the problem?- What are the given information or facts to solve the problem?- What will you do to get the total number of animals they fed?- What words in the problem tell you what to do?
(Words such as how many in all, total number, altogether and sum are called word clues. These words tell us what to do in solving the problem.)
