  1. MULTIPLICATIONREVIEW

  2. Mrs. Cook’s students jumped a total of 1,125 times in a 5 minute period. If they jump the same amount each week of the school year of 36 weeks, how many jumps will her students have accomplished at the end of the year?

  3. 5505 • 6625 • 5625 • 1130

  4. Mr. Levin’s class is running out of dry erase markers. If each of his 19 students brings in two 4 packs of markers, how many markers will the class have?

  5. 19 x ( 2 + 4 ) = ? • 19 x 2 x 4 = ? • ( 19 + 2 ) x 4 = ? • ( 19 x 2 ) + ( 19 x 4 ) = ?

  6. Caleb purchased four boxes of crayons for the class. Each box has 64 crayons. How many crayons did he give to the class? How many crayons if 20 students bring in the same amount of crayons as Caleb?

  7. 4 x ( 64 + 20 ) = ? • ( 4 x 64 ) + ( 64 x 20 ) = ? • 4 + 64 x 20 = ? • 4 x ( 20 x 64 ) = ?

  8. There are 426 students at Orange Elementary School. The PTA is having a spaghetti dinner to raise money for the school. If every student buys three tickets at $6.00 each, how much money will the PTA raise for the school?

  9. 426 x 3 + 426 + 6 = ? • (3 x 6) + (3 x 426) = ? • (6 x 426) x 3 = ? • 6 + 426 x 3 = ?

  10. All of the McDonalds in the County have decided to contribute money toward the schools. If there are 63 McDonalds and they each contribute $150 to the schools, how much will the schools receive?

  11. a. $ 6450 b. $ 3410 c. $ 9450 d. $ 1180

  12. Each of the 4th grade classrooms has an average of 20 students. If there are 4 classrooms at each grade level with the same number of students as 4th grade, about how many students attend our school?

  13. a. 20 x ( 4 + 6 ) = 200 b. 4 + 20 x 6 = 144 c. 4 x 20 + 6 = 86 d. 6 x 80 = 480

  14. Mrs. Ormond orders more books for the Literature Circle selection. If she orders 20 class sets of 20 books each at $15 per book, how much money will she spend?

  15. a. ( 20 + 20 ) x 15 = 600 b. 20 x ( 20 x 15 ) = 6000 c. 20 + 20 + 15 = 55 d. ( 20 x 20 ) + 15 = 415

  16. Use breaking apart to find the answer. 56 x 34

  17. Use breaking apart to find the answer. 49 x 62

  18. Use breaking apart to find the answer. 71 x 29

  19. Use breaking apart to solve. 836 x 45

  21. Emmaly is learning the lattice breaking apart strategy of multiplication. It is like the multiplication grid and looks like this for 235 x 46. 200 + 30 + 5 40 + 6

  22. Use the lattice strategy of breaking apart to solve the problem. 752 x 51 • + 50 + 2 50 + 1

  23. Use the lattice strategy of breaking apart to solve the problem. 123 x 45 100 + 20 + 3 40 + 5

  24. Use the lattice strategy of breaking apart to solve the problem. 235 x 67 200 + 30 + 5 60 + 7

  25. Use the lattice strategy of breaking apart to solve the problem. 368 x 24 300 + 60 + 8 20 + 4

  26. 3 6 4 The Museum of Arts and Sciences is open 364 days each year. If 52 people visit each day, how many people visit each year? Use partial products to solve this problem. 5 2 x 2 x 4 2 x 60 2 x 300 50 x 4 50 x 60 50 x 300 +

  27. What are the partial products created by this problem? • 2 8 + 3 4 4 x 8 4 x 20 4 x 500 30 x 8 30 x 20 + 30 x 500

  28. What are the partial products? • 2 3 4 x 2 5 5 x 4 5 x 30 5 x 200 5 x 1000 20 x 4 20 x 30 20 x 200 20 x 1000
