Instructions
This worksheet will help you learn about making groups! This is the first step to learning multiplication.
- Read the problem about groups.
- In the drawing box, draw the groups required (use small circles, stars, or dots).
- Write the repeated addition sentence to find the total number of items.
Section 1: Making Groups (Repeated Addition)
Example:
| Problem | Drawing Box | Addition Sentence | Total |
|---|---|---|---|
| 3 Groups of 2 Cookies | Draw 3 circles, each containing 2 dots. | 2 + 2 + 2 | 6 |
Practice Problems:
| Problem | Drawing Box (Use this space for your drawings) | Addition Sentence | Total |
|---|---|---|---|
| 4 Groups of 1 Star | |||
| 2 Groups of 5 Apples | |||
| 3 Groups of 3 Blocks | |||
| 5 Groups of 2 Flowers |
Section 2: Building Arrays (Rows and Columns)
An array is a way to line up items in neat rows and columns. Use dots or small shapes to draw the array described.
Example:
| Problem | Drawing Box (Array) | Addition Sentence | Total |
|---|---|---|---|
| 2 rows of 4 dots | \n | 4 + 4 | 8 |
Practice Problems:
| Problem | Drawing Box (Array) | Addition Sentence | Total |
|---|---|---|---|
| 3 rows of 2 circles | |||
| 4 rows of 3 squares | |||
| 5 rows of 1 heart |
Section 3: Matching the Math Language
When we have repeated addition, we can use a shorter way called Multiplication (the 'x' sign). Match the Repeated Addition sentence on the left to the Multiplication sentence on the right.
Draw a line to connect the matching sentences.
| Repeated Addition | Multiplication Sentence | |
|---|---|---|
| 5 + 5 + 5 | 2 x 4 (Two groups of four) | |
| 4 + 4 | 3 x 5 (Three groups of five) | |
| 2 + 2 + 2 + 2 | 4 x 2 (Four groups of two) | |
| 2 + 2 + 2 | 3 x 2 (Three groups of two) |
Section 4: Multiplication Quests (Challenge Problems)
Solve these real-world problems. Show your repeated addition work.
- Sarah has 4 small baskets. She puts 3 shiny marbles in each basket. How many marbles does she have in total?
Show your work (Addition): __
Total Marbles: ____
- A playground has 5 tricycles (small bikes with 3 wheels). How many wheels are on all the tricycles?
Show your work (Addition): __
Total Wheels: ____
- ADVANCED CHALLENGE: If you count 12 legs, and you know there are 4 dogs, how many legs does each dog have? (Hint: Think about 4 groups that add up to 12).
Answer: ____
Answer Key
Section 1: Making Groups (Repeated Addition)
| Problem | Drawing Box | Addition Sentence | Total |
|---|---|---|---|
| 4 Groups of 1 Star | 4 circles with 1 star each | 1 + 1 + 1 + 1 | 4 |
| 2 Groups of 5 Apples | 2 circles with 5 dots each | 5 + 5 | 10 |
| 3 Groups of 3 Blocks | 3 circles with 3 dots each | 3 + 3 + 3 | 9 |
| 5 Groups of 2 Flowers | 5 circles with 2 dots each | 2 + 2 + 2 + 2 + 2 | 10 |
Section 2: Building Arrays (Rows and Columns)
| Problem | Drawing Box (Array) | Addition Sentence | Total |
|---|---|---|---|
| 3 rows of 2 circles | 3 rows of 2 symbols | 2 + 2 + 2 | 6 |
| 4 rows of 3 squares | 4 rows of 3 symbols | 3 + 3 + 3 + 3 | 12 |
| 5 rows of 1 heart | 5 rows of 1 symbol | 1 + 1 + 1 + 1 + 1 | 5 |
Section 3: Matching the Math Language
- 5 + 5 + 5 connects to 3 x 5
- 4 + 4 connects to 2 x 4
- 2 + 2 + 2 + 2 connects to 4 x 2
- 2 + 2 + 2 connects to 3 x 2
Section 4: Multiplication Quests (Challenge Problems)
