STEP BY STEP
TIME TO LEARN
You can use the number line to jump forward 10
Exercise A requires children to figure out the patterns in the counting sequence and jump back 10.

Introduce exercise 1 to children. Help children figure out whether to count on or 65, 75, 85, 95, 105, 115 counting on 10
back and by tens. Exercise B requires children to count on by ten. 65, 55, 45, 35, 25, 15, 5 counting back 10

Introduce exercise 1 to children. Help children to count on by tens.
Ask: How many is 53 and ten more? 63 then count in tens after 63, 73, 83, 93. STEP count on 10

STEP A. Write the missing numbers. count back 10

Introduce exercise 1 to children. Help them count back by tens.
Ask: How many is 108 and ten less? 98 then count back by tens before 98, 88, 2 107, 97, 87 , 77 , 67
78, and 68. B. Count on 10.

Another example: 43 53 63 73 83 93 61 71 81 91 101 111
After solving the Step-By-Step practice, write 51, 61, 71, 31, 91 on the board. C. Count back 10.
Ask: Do you think this pattern is correct if I am counting on by tens? 1 60 70 80 90 100 110 120 2 30 40 50 60 70 80 90
Discuss the answer with children. 68 78 88 98 108 118 39 49 59 69 79 89
This extra example allows children to explain their mathematical thinking and
consider the mathematical thinking of others 278

MULTIPLE INTELLIGENCE ACTIVITY
