  1. Question 1

    What is 23×1523 \times 15 using the standard multiplication algorithm?

  2. Question 2

    Which property of multiplication states that 12×8=8×1212 \times 8 = 8 \times 12?

  3. Question 3

    When multiplying 34×634 \times 6, we can break 34 into 30+430 + 4, multiply each part by 6, and add the results. This is using the distributive property.

  4. Question 4

    An area model is divided into sections for 27×1327 \times 13. What does each section represent?

  5. Question 5

    What is 340×7340 \times 7 using mental math and properties?

  6. Question 6

    Which estimate is closest to 48×5248 \times 52?

  7. Question 7

    The associative property of multiplication says that (5×3)×4=5×(3×4)(5 \times 3) \times 4 = 5 \times (3 \times 4).

  8. Question 8

    Sarah needs to buy 25 notebooks at $16 each. What is the total cost?

  9. Question 9

    What is 56×3256 \times 32 using the standard algorithm?

  10. Question 10

    A farmer plants 18 rows of corn with 24 plants in each row. How many corn plants are there in total?

  11. Question 11

    When using an area model for 15×1415 \times 14, the four sections have areas of 10×10=10010 \times 10 = 100, 10×4=4010 \times 4 = 40, 5×10=505 \times 10 = 50, and 5×4=205 \times 4 = 20.

  12. Question 12

    Which calculation correctly uses the distributive property to find 35×835 \times 8?

  13. Question 13

    What is the best estimate for 63×4963 \times 49?

  14. Question 14

    The number 125 can be written as 5×5×55 \times 5 \times 5, which means 125×2=(5×5×5)×2125 \times 2 = (5 \times 5 \times 5) \times 2.

  15. Question 15

    A bakery bakes 42 batches of cookies with 36 cookies in each batch. How many cookies are baked in total?

  16. Question 16

    Using the standard algorithm to solve 78×2978 \times 29, what is the product?

  17. Question 17

    Both 24×(3×5)24 \times (3 \times 5) and (24×3)×5(24 \times 3) \times 5 give the same answer because of the associative property of multiplication.
