This week Mrs Henderson made us a document. I have improved. I  can answer some under 3 seconds.   Looking for Tens - Triangles - T1 Wk 3

Complete the following:

46 + 4 = 50	37 + 3 = 40	82 + 8 = 90
24 + 6 = 30	71 + 9 = 80	12 + 8 = 20
63 + 7= 70	96 + 4 = 100	58 + 2 = 60
Now try these!
46 + 14 = 60	37 + 13 = 50	82 + 18 = 100
24 + 16 = 40	71 + 19 = 90	12 + 18 = 30
63 + 17 = 80	96 + 14 = 110	58 + 12 = 70
And these!
46 + 34 = 80	37 + 53 = 90	82 + 38 = 120
24 + 46 = 70	71 + 49 = 120	12 + 48 = 50
63 + 37 = 100	96 + 54 = 150	58 + 32 = 90

Can you see any patterns?

Explain the patterns you can see.
