Lesson Plan

Add It Up!

Students will be able to solve addition problems within 10 using manipulatives and by drawing pictures.

Mastering addition within 10 is a fundamental skill that builds confidence and provides a strong base for more complex mathematical concepts in the future.

Audience

1st Grade

Time

30 minutes

Approach

Hands-on exploration and practice.

Materials

Manipulatives (e.g., counting bears, blocks), Slide Deck: Add It Up!, and Worksheet: Plus Power Practice

Prep

Preparation

10 minutes

Gather a variety of manipulatives (counting bears, blocks, unifix cubes) for each student or small group.
* Review the Slide Deck: Add It Up! to ensure familiarity with content and transitions.
* Print enough copies of the Worksheet: Plus Power Practice for each student.
* Ensure pencils and crayons are available for students.

Step 1

Warm-Up: Counting Chant

5 minutes

Begin with a quick counting chant or song to engage students and review number order.
* Ask students to count forward from 1 to 10, then backward from 10 to 1.

Step 2

Introduction to Addition

5 minutes

Use the Slide Deck: Add It Up! to introduce addition as "putting together" or "finding the total number." (Slides 1-3)
* Demonstrate a simple addition problem using large manipulatives (e.g., 2 blocks + 3 blocks = 5 blocks).

Step 3

Hands-On Exploration

10 minutes

Distribute manipulatives to each student or small group.
* Guide students through several addition problems using their manipulatives. (Slides 4-6)
* "Show me 4 bears. Now add 2 more bears. How many do you have altogether?"
* Encourage students to share their answers and explain how they found the total.
* Introduce drawing pictures as another strategy for addition.

Step 4

Worksheet Activity: Plus Power Practice

8 minutes

Distribute the Worksheet: Plus Power Practice.
* Explain that students will solve addition problems by drawing pictures or using their manipulatives.
* Circulate around the room to provide support and assess understanding.

Step 5

Cool-Down & Share

2 minutes

Ask a few students to share one problem they solved on their worksheet.
* Briefly review the main idea: addition is putting numbers together to find a total.

Add It Up! Let's Master Plus!

Today, we're going to become addition superstars! Get ready to put numbers together and find out how many there are in all!

Welcome students and get them ready for a fun math lesson. Remind them about our math goal: to become addition experts!

What is Addition?

Addition means putting two or more groups together.

We find the TOTAL number!

Explain what 'addition' means in simple terms. Use hand gestures to show 'putting together'.

The Plus (+) and Equals (=) Signs

The **plus sign (+) ** means we are adding.

The equals sign (=) means 'is the same as' or 'gives us a total of'.

Show the plus sign and equals sign. Explain their meaning clearly. Write examples on the board as you speak.

Let's Practice Together!

Watch me! If I have 3 red blocks and 2 blue blocks...

How many blocks do I have altogether?

Model an example with large, visible manipulatives. Ask students to count along with you. Emphasize counting all items to find the total.

Your Turn! With Manipulatives!

Everyone, get out your counting tools!

Show me 4.

Now, add 3 more.

How many do you have now? Tell your partner!

Guide students through an example using their own manipulatives. Ask them to show you the first number, then add the second. Circulate to check understanding.

One More!

Let's try another one!

Start with 5.

Add 1 more!

What's your total?

Another guided practice example. Encourage students to articulate their process. 'First I had ____, then I added ____, and now I have ____.'

Time for Plus Power Practice!

Now it's time to show what you know!

You'll get a worksheet to practice adding.

You can use your drawing skills or your counting tools!

Introduce the worksheet. Explain that they can draw or use their manipulatives.

You're Addition Superstars!

Great job today, math learners!

Remember, addition is putting numbers together to find the total.

You are all becoming amazing at adding!

Conclude the lesson by reviewing the main concept. Give positive reinforcement for their hard work. Ask students to give a 'thumbs up' if they feel like an addition expert!

Answer Key

Plus Power Practice Answer Key

Directions: Solve each addition problem.

3 + 2 = 5
Thought Process: Start with 3. Count 2 more: 4, 5. The total is 5.
4 + 1 = 5
Thought Process: Start with 4. Count 1 more: 5. The total is 5.
5 + 3 = 8
Thought Process: Start with 5. Count 3 more: 6, 7, 8. The total is 8.
2 + 6 = 8
Thought Process: Start with 6 (the larger number, easier to count on). Count 2 more: 7, 8. The total is 8.
7 + 0 = 7
Thought Process: Start with 7. When you add 0, the number stays the same. The total is 7.
1 + 8 = 9
Thought Process: Start with 8. Count 1 more: 9. The total is 9.
Draw a picture to show 3 + 4. Then write the answer.
Example Drawing: (Teacher may accept various drawings, e.g., 3 circles + 4 circles)
- ⚪⚪⚪ + ⚪⚪⚪⚪ = ⚪⚪⚪⚪⚪⚪⚪
  3 + 4 = 7
  Thought Process: Draw 3 items. Draw 4 more items. Count all the items together to get 7.
Challenge! If you have 5 apples and your friend gives you 5 more, how many apples do you have?
Thought Process: Start with 5 apples. Count 5 more: 6, 7, 8, 9, 10. The total is 10 apples.
Answer: 10 apples
