Introduction to Multiplication — Answer Key
Part A: Multiple Choice
Circle the best answer for each question.
1. A baker puts 6 muffins on each tray. She fills 3 trays. How many muffins in all?
A) 9
B) 12
C) 18
D) 24
Three trays with 6 muffins each means 3 groups of 6, so multiply 3 x 6 = 18. You can also add 6 + 6 + 6 = 18.
2. There are 4 teams with 5 players each. Which number sentence finds the total?
A) 4 + 5
B) 5 - 4
C) 4 x 5
D) 5 + 5
Four teams is the number of groups and 5 players is the size of each group, so write it as 4 x 5. That equals 20 players in all.
3. A garden has 5 rows with 3 flowers in each row. How many flowers?
A) 8
B) 12
C) 15
D) 18
The garden is an array of 5 rows with 3 flowers in each, so multiply 5 x 3 = 15. Skip counting by 3s five times also gives 15.
4. Each spider has 8 legs. How many legs do 2 spiders have?
A) 10
B) 14
C) 16
D) 18
Two spiders with 8 legs each means 2 groups of 8. Double 8 to get 8 + 8 = 16.
Part B: Fill in the Blank
Write the correct answer on each line.
1. A bike has 2 wheels. There are 7 bikes, so there are 14 wheels.
Seven bikes with 2 wheels each is 7 x 2, which equals 14. Count by 2s seven times to check: 2, 4, 6, 8, 10, 12, 14.
2. Each hand has 5 fingers. Four hands have 20 fingers.
Four hands with 5 fingers each is 4 x 5 = 20. Counting by 5s four times gives 5, 10, 15, 20.
3. A pack holds 6 juice boxes. Three packs hold 18 juice boxes.
Three packs with 6 juice boxes each means 3 x 6 = 18. You can also add 6 + 6 + 6 = 18.
4. Each nest has 4 eggs. Five nests have 20 eggs.
Five nests with 4 eggs each is 5 x 4 = 20. Skip counting by 4s five times also reaches 20.
5. A tricycle has 3 wheels. Six tricycles have 18 wheels.
Six tricycles with 3 wheels each is 6 x 3 = 18. Skip counting by 3s six times gives 3, 6, 9, 12, 15, 18.
