Maths

I am learning to solve subtraction problems by using
1. tidy numbers and
2. place value and splitting

92-49=43
1. 49+1=50 92-50=42+1
2. 92-40=52-9=43

84-38=46
1.38+2=40 84-40=44+2
84-30=54-4=46

I solved these problems by using place value and tidy tens.

Maths

W.A.L.T solve addition problems by going back through the tens.
54-7=48 (54-4=50--3=47)
65-8=57 (65-5=60-3=57)
72-9=63 (72-2=70-7=63)
83-8=75
132-7=125
211-8=203
393-6=387

I solved these problems by going to the tidy tens.

W.A.L.T solve the 6,7,4, using the 5x tables
4x7=28 (5x4)+ (4x2)
6x7=42 (6x5)+ (6x2)
I solved these problems by using the fly flips.
