Now that you know how many of each object Ava found, let’s answer some questions! Click through the slides to challenge yourself!
According to the bar graph, how many objects did Ava find in all? Click the Show Me button once you know the answer. Helpful hint: The words “in all” are telling you to add!
Ava found 63 objects in the junk drawer because \({9 + 5 + 6 + 20 + 17 + 6 = 63}\).
How many more flossers than phone chargers were in the junk drawer? Click the Show Me button to check your thinking. Helpful hint: The words “more” and “than” are telling you to subtract!
There are 12 more flossers than phone chargers because \({17 - 5 = 12}\).
How many fewer key chains than pieces of gum did Ava find? Click the Show Me button when you know! Helpful hint: The word “fewer” in this word problem is telling you to subtract.
Ava found 11 fewer key chains than pieces of gum because \({20 - 9 = 11}\).
What is the combined number of the glow sticks, flossers, and key chains? Think to yourself: “Should I add or subtract?”
There are 32 glow sticks, flossers, and key chains because \({6 + 17 + 9 = 32}\).
What is the difference in the number of pieces of gum and screw drivers? Think to yourself: “What does the word difference tell me to do?”
There are 14 more pieces of gum than screw drivers. 14 is the difference because \({20 - 6 = 14}\).
Are there fewer key chains or glow sticks in the junk drawer? Remember, the word “fewer” also means “less.”
There are fewer glow sticks because there are 6 glow sticks and 9 key chains.
Question
If Ava took 7 of the pieces of gum for herself, how many pieces are left in the junk drawer?
13 pieces of gum are left because \({20 - 7 = 13}\).
