5m
Warm Up: Count the Groups
Begin with visual counting. Use slides 1-2 to identify groups and items. Follow script prompts to emphasize 'groups of'.
5m
Introduction to Repeat Addition
Transition to adding the same number over and over. Use Slide 3 for visual examples (apples). Link back to warm-up patterns.
7m
Activity: Build & Add
Hands-on Practice
Students use manipulatives to build specified groups (e.g., "3 groups of 4"). Verbalize addition sentences: 4 + 4 + 4 = 12.
3m
Worksheet & Cool Down
Distribute practice sheets. Complete 1-2 problems independently. Recap the core concept: Adding the same number repeatedly .
Learning Objective
Students will be able to understand and practice repeat addition as a foundational step towards multiplication, using visual and hands-on methods.
Adding Up Repeatedly Slides Welcome! Let's Count!
Today, we're going to explore something super useful:
Welcome students and introduce "groups".

2. WRITE
3. SOLVE
Practice Makes Perfect!
Look at the groups on your worksheet.
Think about how many items are in each group.
If you need help, just ask!

Great Job, Everyone!
Today, we learned about repeat addition!
It's a super way to count groups of the same number quickly. You all worked hard and did an amazing job!
Keep Practicing!
Group Counting Warm Up Guide Warm Up: Count the Groups
Activating prior knowledge through visual patterns.
Objective
To identify patterns in grouped items and prepare for formal addition sentences.
Step-by-Step Guide
1
Look at the Screen!
Refer to Slide 2 of the lesson presentation. Point to the visual groups shown.
"I will show you some pictures with groups of items. Your job is to tell me how many groups, items per group, and the total!"
2
Let's Try It!
Guide students through Slides 2 and 4 . Use a pointer to count groups first, then items within one group.
Identify Groups
Count Items
3
Think Together
Prompt the class to reflect on the process.
What did you notice about how we counted?
Did we count each one individually, or did we see patterns?
🍩🍩
Teacher Tip:
For students who struggle with abstract counting, use the physical donuts example or actual blocks on the table to mirror the screen.

Required Items
Counting Manipulatives (blocks, counters, or LEGOs)
1
Get Your Manipulatives Ready!
Each student or pair gets a set of counting manipulatives. Clear the desk so you have space to build.
2
Teacher Says, You Build!
Listen to the problem and build the groups. If I say "3 groups of 4", make three separate piles with 4 blocks in each.
Pile 1
🟦🟦
Pile 2
🟦🟦
Pile 3
🟦🟦
3
Count and Add!
Say the repeat addition sentence out loud. Then count ALL the blocks to find the total.
4 + 4 + 4 = 12
Practice Rounds
"Make 2 groups of 5" (5 + 5 = 10)
"Show me 3 groups of 3" (3 + 3 + 3 = 9)
"Build 4 groups of 2" (2 + 2 + 2 + 2 = 8)
Teachers: Circulate and provide verbal praise as students correctly represent groups.

I. Warm Up: Count the Groups
Slide 1: Welcome! Let's Count!
"Good morning/afternoon, everyone! Today, we're going to explore something super useful: counting things in groups! It's like when you have a box of crayons, or a pack of juice boxes. We'll learn how to quickly find out how many there are in total!"
Slide 2: What Do You See?
"Look at the pictures on the screen! I want you to tell me a few things about what you see."
"First, how many groups do you see? For example, how many separate piles or sets are there?" (Pause for response)
"Great! Now, how many items are in each of those groups? Let's count them together in one group." (Pause for response)
"Excellent! Now, if we count ALL the items, one by one, how many are there altogether ?" (Pause for response)
5 MIN
II. Introduction to Repeat Addition
Slide 3: Repeat After Me
"You did a fantastic job counting those groups! Today, we're going to learn a special way to count when we have groups with the same number of items. It's called repeat addition ."
"Repeat addition is when you add the same number over and over again. It helps us count groups faster! Look at the apple example: We have groups of 2 apples. So, we can say 2 + 2 + 2 = 6. We added the number 2, three times."
7 MIN
III. Activity: Build & Add
"Now it's YOUR turn! We are going to use our counting manipulatives to build groups. Look at your Activity sheet. I will give you a problem, and you will build the groups."
Example 1
"Make 2 groups of 5."
Example 2
"Show me 3 groups of 3."
