Find the product: 23 x 14.
Break 14 into 10 + 4.
The product is 322. One way to solve is 23 x 10 = 230 and 23 x 4 = 92, then 230 + 92 = 322. - 2
Find the product: 36 x 27.
The product is 972. You can solve by multiplying 36 x 20 = 720 and 36 x 7 = 252, then adding 720 + 252 = 972. - 3
Find the product: 48 x 15.
Use partial products for 10 and 5.
The product is 720. You can solve by multiplying 48 x 10 = 480 and 48 x 5 = 240, then adding 480 + 240 = 720. - 4
Find the product: 62 x 34.
The product is 2,108. One way to solve is 62 x 30 = 1,860 and 62 x 4 = 248, then 1,860 + 248 = 2,108. - 5
Find the product: 75 x 22.
Break 22 into 20 + 2.
The product is 1,650. You can solve by multiplying 75 x 20 = 1,500 and 75 x 2 = 150, then adding 1,500 + 150 = 1,650. - 6
Find the product: 89 x 31.
The product is 2,759. You can solve by multiplying 89 x 30 = 2,670 and 89 x 1 = 89, then adding 2,670 + 89 = 2,759. - 7
A classroom has 24 boxes of markers. Each box has 18 markers. How many markers are there in all?
Find 24 x 10 and 24 x 8, then add the partial products.
There are 432 markers in all. This is because 24 x 18 = 432. - 8
A bakery makes 47 trays of muffins. Each tray has 12 muffins. How many muffins does the bakery make?
The bakery makes 564 muffins. This is because 47 x 12 = 564. - 9
Use an area model to find 56 x 43. Write the four partial products and the final product.
Break 56 into 50 + 6 and 43 into 40 + 3.
The four partial products are 50 x 40 = 2,000, 50 x 3 = 150, 6 x 40 = 240, and 6 x 3 = 18. The final product is 2,408. - 10
Use partial products to find 68 x 29.
The product is 1,972. One way to solve is 68 x 20 = 1,360 and 68 x 9 = 612, then 1,360 + 612 = 1,972. - 11
Mia says 42 x 36 = 1,412. Check her work and write the correct product.
Multiply 42 by each part of 36.
Mia's answer is not correct. The correct product is 1,512 because 42 x 30 = 1,260 and 42 x 6 = 252, and 1,260 + 252 = 1,512. - 12
A school orders 95 packs of pencils. Each pack has 24 pencils. How many pencils are ordered in all?
The school orders 2,280 pencils in all. This is because 95 x 24 = 2,280.
