3 If Amy had 3 cats and each one had 4 legs, how could we find how many legs all the cats had?

4 =4 legs =12 legs +

5 Another way to figure out the answer is to multiply. Multiplication is a fast way to add equal numbers. Since all 3 cats have 4 legs, instead of adding them together, we could multiply.

6 4 legs 3 cats 12 legs X

7 How many legs altogether would two boys have?

8 Can you think of a multiplication problem that shows this?

9 2 boys 2 legs 4 legs X

10 If a crayon box holds 7 crayons, how many crayons would 2 boxes hold?

11 Can you think of a multiplication problem that shows this?

12 2 boxes 7 crayons 14 crayons X

13 If every teacher has 3 books and there are 5 teachers, how many books do they all have?

14 Can you think of a multiplication problem that shows this?

15 3 books 5 teachers 15 books X

16 If every desk has 1 apple and there are 9 desks, how many apples are there in all?

17 Can you think of a multiplication problem that shows this?

18 1 apple 9 desks 9 apples X

19 Multiplication involves sets of objects. Can you write a multiplcation problem for these sets? I think I can do it!

20 5 sets of 2 each

21 5 X 2 =10

22 3 sets of 4 each

23 3 X 4 = 12

24 3 sets of 3 each

25 3 X 3 = 9

26 4 sets of 2 each

27 4 X 2 = 8

28 6 sets of 3 each

29 3 X 6 = 18

30 5 sets of 4 each

31 5 X 4 = 20

32 On your paper, draw sets to represent each of the following multiplication problems. Then solve the problems. Click on the to find the answer.

33 2 X 9= 5 X 5= 8 X 1= 5 X 1= 4 X 0= 6 X 4=

34 2 X 9=18 Lets try another!

35 5 X 5= Lets try another!

36 8 X 1= Lets try another!

37 5 X 1= Lets try another!

38 4 X 0= Lets try another!

39 6 X 4=
