1 Multiples of 10 and 100 ★★★

Find each product using a basic fact.

1. \(30 \times 4\)
2. \(8 \times 700\)
3. \(9 \times 4{,}000\)
4. \(60 \times 50\)

2 Missing factors ★★★

Find the missing number in each equation.

1. \(7 \times \square = 490\)
2. \(\square \times 600 = 3{,}600\)
3. \(5 \times \square = 45{,}000\)
4. \(80 \times \square = 640\)

3 Complete the area model ★★★

Complete the area model to find \(15 \times 12\). Write the four partial products and then the total.

4 Expanded form ★★★

Use expanded form and partial products to find \(2{,}314 \times 3\).

5 True or false? ★★★

Say whether each statement is true or false. Explain.

1. \(4 \times 30 = 12\)
2. \(6 \times 500 = 3{,}000\)
3. \(20 \times 20 = 40\)
4. \(3 \times 7{,}000 = 21{,}000\)

6 Muffins at the bakery ★★★

A bakery bakes 60 muffins on each tray. How many muffins are on 8 trays?

7 Name the property ★★★

Name the property of multiplication that each equation shows.

1. \(9 \times 4 = 4 \times 9\)
2. \((2 \times 5) \times 7 = 2 \times (5 \times 7)\)
3. \(6 \times (10 + 3) = 6 \times 10 + 6 \times 3\)
4. \(8 \times 1 = 8\)
5. \(0 \times 345 = 0\)

8 4-digit times 1-digit ★★★

Use partial products to find each product.

1. \(1{,}238 \times 5\)
2. \(7{,}052 \times 6\)

9 Two 2-digit numbers ★★★

Find \(34 \times 26\) using two lines of partial products.

10 Area model for 42 times 31 ★★★

Complete the area model and find \(42 \times 31\).

11 Estimate first ★★★

Estimate each product by rounding. Then find the exact product and compare.

1. \(63 \times 28\)
2. \(5{,}917 \times 4\)

12 Find the mistake ★★★

Mia wrote \(3{,}205 \times 4 = 12{,}020\). Is she right? If not, find her mistake and give the correct product.

13 Seats in the stadium ★★★

A stadium section has 48 rows with 65 seats in each row. How many seats are in the section?

14 Mental math with properties ★★★

Use the distributive or associative property to find each product in your head.

1. \(7 \times 98\) (think \(98 = 100 - 2\))
2. \(6 \times 102\)
3. \(25 \times 12\) (think \(12 = 4 \times 3\))

15 Farm stand sales ★★★

A farm stand sells 36 baskets of apples at $14 per basket and 27 baskets of pears at $18 per basket. How much money does the stand earn in all?

16 Cargo ship ★★★

A cargo ship carries 2,468 containers on each trip. It makes 7 trips. (a) How many containers does it carry in all? (b) The company needs to move 20,000 containers. How many more are needed?

17 The missing digit ★★★

The product of a 2-digit number \(4\square\) and 23 is 1,058. Which digit is hidden? Show how you know.

18 Which is greater? ★★★

Without using a calculator, decide which product is greater, \(35 \times 48\) or \(36 \times 47\), and by how much.

19 Fundraiser goal ★★★

A school band wants to raise $5,000. It sells 78 tickets at $62 each. (a) Estimate the money raised. (b) Find the exact amount. (c) Does the band reach its goal? If not, how much is missing?

20 Garden area ★★★

A rectangular garden is 85 feet long and 27 feet wide. (a) Find its area in square feet. (b) A second garden is 3 times as long and has the same width. What is the area of the second garden?

21 Greatest product ★★★

Use each of the digits 2, 3, 4, and 5 exactly once to make two 2-digit numbers. What is the greatest product you can make?
