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.

I am learing to solve two and three dight addition problems using place value.
38+49=87
68+25=93
56+25=81
i sovled these problems by using my place value.
E.g; 58 + 67 =125 (50+60=110)+(8+7=15)
38+49=87
68+25=93
56+25=81
i sovled these problems by using my place value.
E.g; 58 + 67 =125 (50+60=110)+(8+7=15)

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.
4x7=28 (5x4)+ (4x2)
6x7=42 (6x5)+ (6x2)
