Summary
This quick video teaches multiplication as a shortcut for repeated addition, using equal groups (like jars of cookies) to show the connection. It demonstrates that 4 + 4 + 4 (three groups of four) is the same as 3 × 4, both equaling 12, then reinforces the concept using a number line — making three jumps of four to land on 12.
Student Worksheet: Multiplication as Equal Groups
Teacher Note: Students can watch the video lesson above and answer the questions. Click the “Teacher Answer Key” dropdown below when you are ready to review the solutions!
Key Concepts:
• Equal Groups: Groups that all have the same number of items in them.
• Repeated Addition: Adding the same number over and over (like 4 + 4 + 4).
• Multiplication: A shortcut for repeated addition — count the groups, then count how many are in each group.
Instructions: Read each question carefully and write your answer in the space provided.
- Question 1: What are “equal groups”?
- Question 2: Write the repeated addition sentence for 3 jars with 4 cookies in each jar.
- Question 3: Write the multiplication sentence that matches that same repeated addition.
- Question 4: Using a number line, how many jumps of 4 would you make to reach 12? Where would you land?
- Question 5: Draw your own picture of equal groups (like jars, boxes, or plates), then write both the addition and multiplication sentence for it.
