3. 15, 05, 35, 75, 85, 65, 25, 85, 95, 45

LESSON TWO – ORDERING WHOLE NUMBERS OF UP TO 200

Teacher’s/Pupil’s Activities – Displays a chart of scattered numbers up to 200 for the pupils to identify and rearrange. Guide them through.

For example,

1. 112, 119, 118, 116, 111, 117, 115, 114, 110

Solutions

Guides the pupils to identify by reading the numbers and to compare each digit from left to right.

Common digits are 11

112, 119, 118, 116, 111, 117, 115, 114, 110

The difference in each number are –

__2, __9, __8, __6, __1, __7, __5, __4, __0

Arrange in ascending order –

__0, __1, __2, __3, __4, __5, __6, __7, __8, __9

Therefore, add 11 as in 110, 111, 112, 113, 114, 115, 116, 117, 118, 119

 

2. 160, 120, 190, 180, 150, 170, 130, 140, 110
