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
