Which expression can be used to find the product of 37 and 50?

• (30 x 7) + (50 x 0)

• (3 x 50) + (70 x 50)

• (30 x 50) + (7 x 50)

• (3 x 50) + (7 x 50)

Which is the correct equation shown by the model?

• 14 x 14 = 196

• 14 x 16 = 224

• 16 x 14 = 204

• 16 x 14 = 256

Find the product. 56 x 12

• 68

• 72

• 662

• 672

Which shows the correct partial products and the product that is shown by the area model?

• 46 x 35 = 1,200 + 18 + 120 + 30 = 1,368

• 46 x 35 = 1,200 + 180 + 200 + 30 = 1,610

• 46 x 35 = 120 + 1,800 + 200 + 30 = 2,150

• 46 x 35 = 120 + 180 + 2,000 + 30 = 2,330

Which expression can be used to correctly find the product of 54 and 70?

• (5 x 40) + (4 x 70)

• (5 x 70) + (4 x 70)

• (50 x 4) + (70 x 0)

• (50 x 70) + (4 x 70)

The craft store sold 89 rolls of ribbon. There were 27 feet of ribbon on each roll. Part A: Which expression can be used to find the product of 89 and 27?

• (8 x 2) + (80 x 7) + (9 x 2) + (9 x 7)

• (80 x 2) + (8 x 7) + (9 x 20) + (9 x 7)

• (80 x 20) + (80 x 7) + (9 x 2) + (9 x 7)

• (80 x 20) + (80 x 7) + (9 x 20) + (9 x 7)

Which shows the correct partial products and the product that is modeled by the array?

• 25 x 26 = 400 + 100 + 120 + 30 = 650

• 25 x 26 = 400 + 10 + 120 + 30 = 560

• 25 x 26 = 200 + 100 + 120 + 30 = 650

• 25 x 26 = 40 + 30 + 12 + 30 = 112
