Multiplication Magic 2

 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 = 1, 2, 4, 8, 16




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




A prime number is a whole number greater than 1




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 = 66750

200 x 267 = 53400

50 x 267 = 13350
