c.       Intuitive concept of length

IV.             Material :

·         Picture of three girls

V.                Instructional Procedures :

A.    Posing the problem

Show a drawing of three girls and tell the pupils, “charm, althea, and crystal just had their hair cut. What can you say about the length of their hair ?

Ask the pupils these questions : who are the girls in the picture ? (the girls in the picture are charm, althea, and crystal). What did they just have ? (they just had their hair cut). What can you say about the length of their hair ? possible answer : (all of them have short hair, althea’s and crystal’s hair are shorter than charm’s hair, crystal’s hair is shorter than althea’s hair, among the three, crystal’s hair is the shortest).

 

Post the problem below on the board. Ask the pupils to read the problem aloud. Problem : charm, althea, and crystal had their hair cut. If you will arrange them according to the length of their hair, who will come first, second, and third ?

B.     Solving the problem

Ask the pupils to arrange the girls according to the length of their hair, tell the pupils to write the name of the girls in order. Have them identify who is the first girl, the second, and the third.

(possible answer : 1^st - Charm,          2^nd – Althea     3^rd – Crystal

                              1^st - Crystal,         2^nd – Althea     3^rd – Charm

C.     Processing the answers/ solutions

Ask some pupils to give their answer. Write their answer on the board. Ask them, “why did you arrange the girls this way : Charm, althea, crystal ?” ( the girls were arranged starting with the one with short hair to the one with shortest hair).

Introduce the words shorter and shortest. Recall the answer given by the pupils, guide the pupils in telling the arrangement of the girls using these words (charm’s hair is short. Althea’s hair is shorter. Crystal’s hair is the shortest).

Focus the pupils attention to other answer given. Ask, “why did you arrange the girls this way : crystal, althea, charm ?” (the girls were arranged starting from the one with the shortest hair to the one with short hair).

Focus the pupils attention to the skirt the three girld are wearing. Ask the pupils,”what can you say about the length of their skirts ?’ (all of them have long skirts. The length of their skirts is different).

Introduce the word long. If you will arrange the girls according to the length of their skirt, who will come first, second, and third ? (possible answers :

1^st – Crystal,    2^nd – Althea,    3^rd – Charm

1^st – Charm,     2^nd – Althea,    3^rd – Crystal

Ask the pupils why they arranged the girls this way : crystal, althea, charm. (the girls were arranged starting with the one wearing the long skirt to the one wearing the longest skirt).

Introduce the words longer and longest. Guide the pupils in telling the arrangement of the girls using these words (crystal’s skirt is long, althea’s skirt is longer. Charm’s skirt is the longest).

Focus on the pupils attention to the other answer given. Ask them why they arranged the girls this way : charm, althea, crystal. (the girls were arranged starting with the one wearing the longest skirt to the one wearing a long skirt).

D.    Reinforcing the concept/ skill

Let the pupils do worksheets 1 and 2. Then discuss the answer.

E.     Summarizing the lesson

The length of an object is its measure from one end to the other end. We can compare the length of objects by telling which is short, shorter, shortest. We can also compare their lengths by telling which is long, longer, longest.

F.      Applying to new and other situations

Let the pupils do the home activity. The activity may be done as assignment.
