We have been really enjoying our maths this year!! This week we have been looking at equal addition and equal subtraction problem solving activities! We used bead strings, counters and dienes to help us.
Two questions we have focused on is:
What is the same? What is different?
Can you spot the pattern with these equations?
120 – 90 = 30
122 – __ = 30
__ – 89 = 30
