MultiplicationMultiplication is taking a number, (like 5) and adding it a certain amount of times (7 times)It is expressed in the term5 x 7 = 35

DivisionDivison is taking a number (like 35) and splitting it up into groups of another number (like 5)It is expressed in the term35 / 5 = 7

Multiplicaton and Divison are related. Look at the problems below, can you see how they are simmilar?5 X 7 = 35 35 / 5 = 77 x 5 = 35 35 / 7 = 5

5 x 7 is the same as adding 5 seven times5+5+5+5+5+5+5 = 35the same as 5 x 7 = 35

35 / 5 is the same as minsing 5 seven times.35 - 5 = 30 1 time30 - 5 = 25 2 times25 - 5 = 20 3 times20 - 5 = 15 4 times15 - 5 = 10 5 times10 - 5 = 5 6 times5 - 5 = 0 7 timesthe same as 35 / 5 = 7

Now try finding the answers to50 / 545 / 540 / 535 / 530 / 525 / 520 / 515 / 510 / 55 / 5

Now try finding the answers to 5 x 15 x 25 x 35 x 45 x 55 x 65 x 75 x 85 x 95 x 10

Hint: you can use the multiples of 5 to help you find the answer

Hint: you can use the multiples of 5 to help you find the answer

Below are the multiples of 5

Dividing any number by itself will always give you the answer one5 / 5 = 1

Dividing any number by one will give you your original number5 / 1 = 5

Multiplying any number by one will give you your original number5 x 1 = 5
