Multiplication Magic

  Multiplication Magic
We are learning to use place value to solve multiplication problems using whole numbers.

Times table practice:
5 x 5 =25                                    7x7=49
4 x 4=16                                     8 x 8=64
3 x 3 =9                                   11x 11=121
6 x 6=36                                     5 x 4=20
9 x 9 =81                                    10 x 10=100

Factors of 16 =8, 2, 1, 16

Multiples of 8 =   8,16,24,32,40,48,56,64,72,80

A prime number is 

25 x 25 =625
20 x 25 =500
5 x 25 =125


25 x 245 =6125
200 x 25 =5000
40 x 25 =1000
5 x 25 =125

267 x 250 =66.750
200 x 267 =53400
50 x 267 =13.350
