**Spark Your Learning**

Ling is at a fair with her friends Jimmy and Pablo. At a game booth, they each get 4 balls. How many balls do Ling and her friends get?

**Show more than one way to find the number of balls.**

Answer:

Explanation:

Ling is at a fair with her friends Jimmy and Pablo

At a game booth, they each get 4 balls

There are 3 friends

Each friend gets 4 balls

3 groups of 4

So, 3 x 4 = 12

Therefore, Ling and her friends get 12 balls.

Answer:

Explanation:

To win the ball-in-basket game

Reg needs to get both of the 2 game balls in the basket

Reg wins the game 4 times

4 groups of 2

So, 4 x 2 = 8

2 + 2 + 2 + 2 = 8

The addends are equal, they follow increasing pattern

Therefore, Reg get 8 balls in the basket.

**Turn and Talk** Why does using repeated addition help you find how many balls Reg gets in the basket?

2. There are 3 players playing ring toss. Each player gets 5 rings. How many rings do the players get?

**Show equal groups. Write an addition equation to find the number of rings.**

A. What multiplication equation can you write for the addition equation?

B. How many rings do the players get? ____

Answer:

Explanation:

There are 3 players playing ring toss

Each player gets 5 rings

5 + 5 + 5 = 15

Therefore, the players will get 15 rings.

Connect to Vocabulary

When groups are equal, you can multiply to find how many in all.

Multiplication Equation

4 groups of 2 items in each group = 8 items in all

The factors are the numbers being multiplied. The product is the answer to a multiplication problem.

Question 1.

There are 8 players at the fish bowl game. Each player gets 3 balls. Write an addition and a multiplication equation for the problem. How many balls do the 8 players get?

__________________________

__________________________

Answer:

24 balls

Explanation:

There are 8 players at the fish bowl game

Each player gets 3 balls

3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 = 24

Or 8 x 3 = 24

So, 8 players will get 24 balls.

Question 2.

**Model with Mathematics** Ervin buys 5 packs of postcards like these. How many postcards are in the packs?

- Write an addition equation to model the problem. ____________
- How many postcards are there? ___________

Answer:

Ervin buys 5 packs of postcards like these

There are 8 cards in each pack

8 + 8 + 8 + 8 + 8 = 40

So, there are 40 postcards in 5 packs.

Question 3.

Hal packs 4 bags of potatoes. What is the weight of the 4 bags of potatoes?

- Write an addition equation and a multiplication equation.

Add. _______

Multiply. _______ - What is the weight of the 4 bags of potatoes? _______

Answer:

Hal packs 4 bags of potatoes

Each bag of potato weighs 9 pounds

4 bags of 9 pounds

9 + 9 + 9 + 9 = 36 or

4 x 9 = 36

So, The weight of 4 bags of potatoes is 36 pounds.

Question 4.

**Attend to Precision** Diya writes 7 × 9 = 63 to find the number of players on 7 baseball teams. Describe what each of the factors represents in the multiplication equation. Explain your thinking.

Answer:

When groups are equal, you can multiply to find how many in all.

Multiplication Equation

7 x 9 = 63

7 teams of 9 players in each team = 63 players in all

The factors are the numbers being multiplied

The product is the answer to a multiplication problem

7 represents the number of teams

9 represents the number of players in each team

So, 63 is the number of players in all the 7 teams.
