Three friends meet to share their rock collections:• Sarah has two rocks.• Camilla has three times as many rocks at Sarah.• Zachary has four times as many rocks as Camilla1. Find the number of rocks that each child collected. 2. How many rocks did the children collect altogether? 3. Draw a bar diagram to show how many rocks Zachary and Camilla have together.4. Show Zachary’s total using repeated addition.Part 2Each child painted three rocks and sold them at a craft show. Answer the following questions:1. How many rocks did the children sell altogether? Write a multiplication equation to help you.2. Each rock sells for $5.00. How much money did they make altogether? Draw a bar diagram to help you.

Answer 1

1) Sarah: 2

Camilla: 3 x 2 =6

Zachary: 4 x (3x2) =24

2) 32 rocks

3) Check the graph below, please.

1) Gathering the data:

Sarah: 2

Camilla: 3 x 2 =6

Zachary: 4 x (3x2) =24

2) To find out the total number of rocks we have to add them up:

`2+6+24=32`

3) Let's sketch out a bar diagram:

Hence, the answer is:

1) Sarah: 2

Camilla: 3 x 2 =6

Zachary: 4 x (3x2) =24

2) 32 rocks

3) Check the graph, above
