Exercises 1 to 6 require children to add tens using place value charts and + 3 0
number sentences. 8 0
5 tens + 3 tens = 8 tens
Introduce the exercise 1 to children. 50 + 30 = 80
Ask: How many is 4 + 5? 9 ones You already know
How many is 4 tens + 5 tens? 9 tens 5 ones + 3 ones = 8 ones
5 + 3 = 8
How many is 40 + 50? 90

Another example: 1 4 + 5 = 9 4 Tens Ones
After solving the Step-By-Step practice, write 7 tens + 2 tens = ___ on the board. + 1 4 0 0
Give the children time to try and solve the problem. Then, say: 7 tens is 70 and 2 40 + 50 = 90 5 0
tens is 20, then 70 + 20 = 90 or 7 tens + 2 tens is 9 tens. 9 tens is 90. Tens Ones
