10. Multiplication Vocabulary Review 5 x 7 = 35 factor times product

11. Multiplication Vocabulary Review array row

12. Glossary Array: A way of displaying objects in rows and columns. Factors: Numbers that are multiplied together to give a product. Product: The answer to a multiplication problem. Times: The symbol that means to multiply the factors on either side.

14. Example 1 What multiplication sentence does the array model? A. 2x5=10 B. 4x3=12 C. 8x4=32 D. 2x3=6 The first factor is the number of rows (2) and the second factor is the number of things in each row. (3) The product is the number in all. (6) So, the array shows 2x3=6.

15. Example 2 What multiplication sentence does the array model? A. 2x5=10 B. 4x3=12 C. 3x4=12 D. 2x3=6 The first factor is the number of rows, (3) and the second factor is the number of things in each row. (4) The product is the number in all. (12) So, the answer is C, B is incorrect because the factors are in the wrong order!

16. Example 3 What multiplication sentence does the array model? A. 4x4=16 B. 4x3=12 C. 5x4=20 D. 5x5=25 The first factor is the number of rows. (4) and the second factor is the number of things in each row. (4) The product is the number in all. (16) So, the answer is 4x4=16.

35. Review Number 1 The first factor is the number of rows (2). The second factor is the number of things in each row (6). The product is the number of things in all (12). So the multiplication sentence modeled by this array is 2x6=12.

36. Review Number 2 The first factor is the number of rows (3). The second factor is the number of things in each row (5). The product is the number of things in all (15). So the multiplication sentence modeled by this array is 3x5=15.

37. Review Number 3 The first factor is the number of rows (1). The second factor is the number of things in each row (7). The product is the number of things in all (7). So the multiplication sentence modeled by this array is 1x7=7.

38. Review Number 4 The first factor is the number of rows (6). The second factor is the number of things in each row (3). The product is the number of things in all (18). So the multiplication sentence modeled by this array is 6x3=18.

39. Review Number 5 RETURN TO RESULTS RETURN TO RESULTS The first factor is the number of rows (6). The second factor is the number of things in each row (5). The product is the number of things in all (30). So the multiplication sentence modeled by this array is 6x5=30.
