###### INTRODUCTION
1. Show students a number line poster and review the numbers from 1 to 10.
2. Explain to students that a number line is a tool that helps us count and solve addition problems.
3. Ask students to count aloud with you as you point to each number on the number line.
###### INSTRUCTION
1. Introduce addition sentences and show students how to use the number line to solve simple addition problems.
2. Write an addition sentence on the board, such as "2 + 1 = ?"
3. 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.
4. Repeat the process with a few more addition sentences.
5. Demonstrate how to match each addition sentence to its corresponding number line model.
###### GUIDED PRACTICE
1. Distribute addition sentence cards and manipulatives to small groups of students.
2. Instruct students to match the addition sentence cards to their corresponding number line models and, if needed, use the manipulatives to solve the problems.
3. Circulate the room to provide support and guidance as needed.

###### INDEPENDENT PRACTICE
1. Provide students with a worksheet containing addition sentences and number line models.
2. Instruct students to match the addition sentences to their corresponding number line models and solve the problems independently.
3. Encourage students to use manipulatives to help them solve the problems.

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

###### EXIT TICKET
1. 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
1. Ask students to share one addition sentence they solved and how they solved it.
2. Use their responses to assess their understanding of using the number line to solve addition problems.

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

###### EXTENSION
1. Students can practice solving more complex addition problems using the number line.
2. Students can create their own addition sentences and number line models for a partner to solve.
###### INTERVENTION
1. For students who struggle with fine motor skills, larger manipulatives can be used.
2. 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).
