Identify Repeated Addition for Equal Groups
π¦ Adding the same number over and over? That's called Repeated Addition, and it's the secret doorway to learning multiplication!
Do this: Read the concept below, then try the quiz or activity.
Concept
When you have groups of things that are perfectly equal, you can use a special kind of addition.
π― Equal Groups: Imagine 3 boxes of donuts. Every single box has exactly 4 donuts inside. * Box 1: 4 donuts * Box 2: 4 donuts * Box 3: 4 donuts
Instead of counting every single donut one by one, we write a repeated addition sentence! 4 + 4 + 4 = 12.
We "repeated" the number 4 exactly three times, because there are three groups!
Try it
Read the equal groups!
Instructions: Look at the story and choose the correct repeated addition sentence.
Problem 1: You have 4 bags of apples. There are 5 apples in EVERY bag. Which sentence matches? A) 4 + 5 = 9 B) 5 + 5 + 5 + 5 = 20 C) 4 + 4 + 4 + 4 = 16
Problem 2: You see a picture of 2 nests. Each nest has 3 eggs. What is the repeated addition sentence? * Equation: ___ + ___ = ___
Problem 3: Look at this sentence: 6 + 6 = 12. Which story matches it? A) 6 kids got 6 more toys. B) 2 teams have 6 players each.
