  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 =

Multiples of 8 =   ,80

A prime number is 

25 x 25 =625

20 x 25 =500

5 x 25 =125

25 x 245 =

200 x 25 =

40 x 25 =

5 x 25 =

267 x 250 =

200 x 267 =

50 x 267 =
