Lesson 5-2
Multiply by 6
1. The pet store has 6 dogs. Each dog is walked 5 times each day. How many walks are needed each
day?
Use an array to find 6 × 5.
So, 30 walks are needed each day.
2. Hannah has 18 stickers. She divides them equally among her 3 best friends. How many stickers does
each friend get?
To solve this problem, you can use a number sentence.
3 × = 18
3 × 6 = 18
THINK: What times 8 equals 18?
The missing number is 6. So, each friend gets 6 stickers.
3. Justin has 6 bags of marbles. There are 8 marbles in each bag. How many marbles does he have in
all?
You can use doubling to find 6 × 8.
Step 1
6 is the double of 3, so 6 × 8 is the double of 3 × 8.
Step 2
6×8
Step 3
So, 6 × 8 = 48. Justin has 48 marbles.
=
3×8
+
3×8
