Today we are revising our addition and subtraction skills.
REMEMBER We have strategies that can help us.
Break the numbers into chunks that are more helpful
23 + 42 =
20 + 3 + 40 + 2 = 65 adding the 20 and 40, then the 3 and 2
87 - 24 =
87 - 20 - 4 = 63 taking 20, leaves 67
then taking 4, leaves 63
