The document introduces multiplication as a way to efficiently calculate the total number of objects when grouped into equal sets. It provides examples of multiplying the number of sets by the number of objects in each set to find the total number of legs for multiple cats, number of crayons in multiple boxes, number of books for multiple teachers, and number of apples on multiple desks. The document encourages representing multiplication problems using sets and solving related problems.

1. Make It Multiply! Created by Jimmy Dodson

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

3. =4 legs =4 legs =4 legs =12 legs +

4. 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.

5. 4 legs 3 cats 12 legs X

6. How many legs altogether would two boys have?

7. Can you think of a multiplication problem that shows this?

8. 2 boys 2 legs 4 legs X

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

10. Can you think of a multiplication problem that shows this?

11. 2 boxes 7 crayons 14 crayons X

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

13. Can you think of a multiplication problem that shows this?

14. 3 books 5 teachers 15 books X

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

16. Can you think of a multiplication problem that shows this?

17. 1 apple 9 desks 9 apples X

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

19. 5 sets of 2 each

20. 5 X 2 =10

21. 3 sets of 4 each

22. 3 X 4 = 12

23. 3 sets of 3 each

24. 3 X 3 = 9

25. 4 sets of 2 each

26. 4 X 2 = 8

27. 6 sets of 3 each

28. 3 X 6 = 18

29. 5 sets of 4 each

30. 5 X 4 = 20

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

32. 2 X 9= 5 X 5= 8 X 1= 5 X 1= 4 X 0= 6 X 4=

33. 2 X 9=18 Let’s try another!

34. 5 X 5= Let’s try another!

35. 8 X 1= Let’s try another!

36. 5 X 1= Let’s try another!

37. 4 X 0= Let’s try another!

38. 6 X 4=
