Motivation Introduce the puppet. He is math man. He has a big farm. He likes to share his fruits and vegetables. This morning, he gathered 8 fruits. He is thinking of giving these to four good children. Who among you would like to have some fruits and vegetables from math man’s farm? A whole, a whole divided into two one part is called one half and so the other one 5 A whole, a whole divided into four one part is called one fourth and so the other three 8 A whole, a whole divided into two one part is called one half and so the other one 4 A whole, a whole divided into four one part is called one fourth and so the other three 10 “Me, Teacher!” 1. Presentation a. Show math man’s farm How will Math man separate 8 fruits for the 4 children? Would you like to guess how many will each child get?
- 3. Write it on your Show-Me-Board Call four pupils in front. Have them stand in a row. Give each pupil one fruit at a time until all the fruits were given. Does each child have the same number of fruits? What is ¼ of 8? Exactly! Who guessed it right? Check the pupils’ guess. Award the guavas to those who had guessed it right. Do the same procedure in separating the other fruits in the farm like: 20 bananas, 12 mangoes, 16 atis. b. Role Playing Call some pupils. Have the pupils act out the situation and demonstrate how each set of objects can be separated into fourths. 1. Math man has 12 bananas. He wants to Share them equally among his 4 friends. How many does each of his friends receive? What is ¼ of 12? 2. Math man has 16 okras. He wants to give equal number of okras to four mothers. How many will each mother get? What is ¼ of 16? 3. Math man has 20 atis. His 4 classmates want to have an equal number of atis. How many will each of his friends get? What is ¼ of 20? 2.
