Tuesday

Today we will be adding and subtracting ten from a two-digit number. 

 

Task 1: Use the 100 square to count on and back in tens from a given number e.g. Can you start at 3 and count on in tens (13, 23, 33, 43....). Can you start at 93 and count back in tens (93, 83, 73.....).

 

Task 2: Write the addition and subtraction number sentences to match the sequence.

 

Example:

3 + 10 = 13                               93 - 10 = 83

13 + 10 = 23                             83 - 10 = 73

23 + 10 = 33                             73 - 10 = 63

 

Challenge: Complete the sequence starting at a different number.
