### LESSON INSTRUCTION

###### INTRODUCTION

- Show students a number line poster and review the numbers from 1 to 10.
- Explain to students that a number line is a tool that helps us count and solve addition problems.
- Ask students to count aloud with you as you point to each number on the number line.

###### INSTRUCTION

- Introduce addition sentences and show students how to use the number line to solve simple addition problems.
- Write an addition sentence on the board, such as "2 + 1 = ?"
- Model how to use the number line to solve the problem by starting at 2 and counting up one more space to land on 3.
- Repeat the process with a few more addition sentences.
- Demonstrate how to match each addition sentence to its corresponding number line model.

###### GUIDED PRACTICE

- Distribute addition sentence cards and manipulatives to small groups of students.
- Instruct students to match the addition sentence cards to their corresponding number line models and, if needed, use the manipulatives to solve the problems.
- Circulate the room to provide support and guidance as needed.

###### INDEPENDENT PRACTICE

- Provide students with a worksheet containing addition sentences and number line models.
- Instruct students to match the addition sentences to their corresponding number line models and solve the problems independently.
- Encourage students to use manipulatives to help them solve the problems.

###### HOMEWORK

- Assign students to practice using the number line to solve addition problems at home.
- Provide them with a worksheet or a set of addition problems to solve using the number line.
- Encourage students to use manipulatives or drawings to help them solve the problems.
- Remind students to show their work and write down the addition sentences and answers.
- Collect the completed homework the following day and review it with the students to reinforce their learning.

###### EXIT TICKET

- Provide each student with an exit card and instruct them to write an addition sentence and match it to its corresponding number line model.

###### ASSESSMENT

- Ask students to share one addition sentence they solved and how they solved it.
- Use their responses to assess their understanding of using the number line to solve addition problems.

###### CLOSURE

- Summarize with the students what they have learned about using the number line to solve addition problems.
- Remind students that using the number line is a helpful tool in solving addition problems.
- Encourage students to continue practicing using the number line to solve addition problems at home to strengthen their understanding and skills.

###### EXTENSION

- Students can practice solving more complex addition problems using the number line.
- Students can create their own addition sentences and number line models for a partner to solve.

###### INTERVENTION

- For students who struggle with fine motor skills, larger manipulatives can be used.
- For students who need extra support, a visual aid or diagram can be provided to help them understand the concept of using the number line to solve addition problems.

###### VIDEOS

No Video Available

### TEACHING TIPS

- Use concrete manipulatives to help students understand the concept of addition.
- Provide plenty of opportunities for students to practice using number line models to solve addition problems.
- Encourage students to explain their problem-solving strategies to their peers.

### STUDENT MISCONCEPTIONS

- Some students may struggle to understand the concept of addition and may need additional support and practice.
- Some students may not understand how to use the number line to solve addition problems and may need guidance and modeling.
- Some students may struggle with memorizing addition facts and may need additional practice and support in this area.

### STANDARD

##### Common Core Standard:

1.OA.C.5 - Relate counting to addition and subtraction (e.g., by counting on 2 to add 2).
