Equations as comparisons

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

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

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

The reptile house has 9 turtles and 45 crickets. A zookeeper writes 45 = 5 × 9. Which sentence matches the equation?

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

Match each zoo fact to the equation that shows the comparison. One equation is not used.

Write comparison equations

Turn each comparison sentence into a multiplication equation.

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 + 3B. 3 = 6 × bC. b = 6 × 3D. 6 = 3 × b

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.
