About this worksheet

What students practice

  • Students interpret a multiplication equation as a comparison stated two ways.
  • Students write multiplication equations for times-as-many comparison sentences.
  • Students use a letter for the unknown number in a comparison equation.

How to use

Do problem 1 together and say 48 = 6 × 8 aloud both ways. Students can draw tape diagrams to show each comparison before they choose or write an equation.

Curriculum

Common Core standard covered

4.OA.A.1

Times as Many at the Zoo

Read multiplication equations as comparisons and write comparison equations.

Equations as comparisons

Read each equation as a times-as-many comparison.

1.
Read the equation 48 = 6 × 8. Finish both comparison sentences.

48 is   times as many as 8.
48 is   times as many as 6.

2.
The reptile house has 9 turtles and 45 crickets. A zookeeper writes 45 = 5 × 9. Which sentence matches the equation?
  • A. There are 5 more crickets than turtles.
  • B. There are 5 times as many turtles as crickets.
  • C. There are 5 times as many crickets as turtles.
  • D. There are 45 times as many crickets as turtles.
3.
The meerkat exhibit has 10 meerkats and 50 beetles. The equation is 50 = 5 × 10.

There are   times as many beetles as meerkats.

4.
Circle every sentence that matches the equation 36 = 4 × 9.

36 is 4 times as many as 9.36 is 4 more than 9.36 is 9 times as many as 4.9 is 4 times as many as 36.36 is 9 more than 4.

5.
Match each zoo fact to the equation that shows the comparison. One equation is not used.
  1. There are 9 seals and 54 fish. That is 6 times as many fish as seals.
  2. There are 7 monkeys and 56 bananas. That is 8 times as many bananas as monkeys.
  3. There are 10 goats and 30 children at the petting zoo. That is 3 times as many children as goats.
  4. There are 3 lions and 21 visitors at the window. That is 7 times as many visitors as lions.
  1. A. 21 = 7 × 3
  2. B. 54 = 6 × 9
  3. C. 30 = 10 + 20
  4. D. 56 = 8 × 7
  5. E. 30 = 3 × 10

Write comparison equations

Turn each comparison sentence into a multiplication equation.

6.
The giraffe yard has 3 giraffes. The keeper hangs 6 times as many leaf bundles as giraffes. Let b stand for the number of leaf bundles. Which equation shows this comparison?
  • A. b = 6 + 3
  • B. 3 = 6 × b
  • C. b = 6 × 3
  • D. 6 = 3 × b
7.
A giraffe is 15 feet tall. The fence next to it is 5 feet tall. The giraffe is 3 times as tall as the fence. Complete the equation.

  = 3 ×  

8.
The bird house has 6 parrots. It has 7 times as many finches as parrots. Let f stand for the number of finches.

f = 7 ×  , so f =   finches.

9.
The zoo gift shop has 24 stickers. Each sentence matches one equation. Sort the sentences.
24 is 3 times as many as 8.24 is 6 times as many as 4.24 is 8 times as many as 3.24 is 4 times as many as 6.24 is 12 times as many as 2.24 is 2 times as many as 12.
24 = 3 × 824 = 4 × 624 = 2 × 12

Think it through

Use what you know about times-as-many comparisons.

10.
Which statement about 63 = 7 × 9 is true?
  • A. 63 is 7 times as many as 9, but it is not 9 times as many as 7.
  • B. 9 is 7 times as many as 63.
  • C. 63 is 7 times as many as 9, and it is also 9 times as many as 7.
  • D. 63 is 7 more than 9.
11.
Fill in the missing number in each comparison.

72 is   times as many as 9.
  is 6 times as many as 7.
64 is 8 times as many as  .

12.
The reptile house has 6 frogs. It has 3 times as many snakes as frogs. Diego says that means there are 3 more snakes than frogs, so there are 9 snakes. Explain Diego's mistake. Write an equation for the number of snakes, s, and solve it.
