### LESSON INSTRUCTION

###### INTRODUCTION

- Begin the lesson by asking the students to raise their hands if they have ever counted to ten before.
- Ask the students to count to ten together.
- After the students have counted to ten, ask them to count to eleven together.
- Point out that counting to eleven is just like counting to ten, but with one more number.
- Tell the students that today they will be learning about adding one.

###### INSTRUCTION

- Show the students addition flashcards with the sum of 1 and another number (e.g., 1+2, 1+3, etc.).
- Demonstrate how to solve each addition problem using manipulatives (such as counters, cubes, or fingers) and a number line, if available.
- Explain that adding one means counting one more than the starting number.
- Practice saying the addition sentences with the students, emphasizing the word "one" in each sentence.

###### GUIDED PRACTICE

- Provide each student with a worksheet containing addition sentences with the sum of 1 and another number.
- Work through the problems together as a class, using manipulatives or a number line to solve the problems.
- Encourage the students to use their fingers to help them count up by one.
- Ask the students to say the addition sentence out loud after solving each problem.

###### INDEPENDENT PRACTICE

- Provide each student with another worksheet of addition sentences with the sum of 1 and another number to complete independently.
- Circulate around the room to provide support and guidance as needed.

###### HOMEWORK

- Ask the students to find objects at home and write an addition sentence adding 1 that represents the objects (e.g., 1+2 = 3 apples).
- Encourage the students to use manipulatives or fingers to help them solve the problem.

###### EXIT TICKET

- Provide each student with a whiteboard and marker.
- Instruct the students to write an addition sentence adding 1 and solve the problem using manipulatives or fingers.
- Check the students' work to assess their understanding of the addition concept of adding 1.

###### ASSESSMENT

- Ask the students to share one addition sentence adding 1 they solved and how they solved it.
- Use their responses to assess their understanding of the addition concept of adding 1.

###### CLOSURE

- Review with the students what they learned about the addition concept of adding 1.
- Encourage the students to practice solving addition sentences adding 1 using manipulatives, fingers, and number lines.

###### EXTENSION

- Students can practice solving addition sentences adding 2, 3, or more.
- Students can practice solving addition sentences without using manipulatives or fingers.
- Students can practice writing their own addition sentences adding 1 and solving them.

###### INTERVENTION

- For students who struggle with fine motor skills, larger and easier to grasp 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 adding 1.

###### VIDEOS

No Video Available

### TEACHING TIPS

- Use manipulatives like counters, cubes, or fingers to help students visualize adding 1.
- Incorporate fun activities like games and puzzles to keep students engaged and motivated.
- Provide opportunities for students to practice solving addition sentences on their own and in pairs.

### STUDENT MISCONCEPTIONS

- Students may confuse addition with subtraction, especially when presented with word problems.
- Students may struggle to understand the concept of "adding 1" and may need additional practice using manipulatives or a number line.
- Students may make errors in counting and skip numbers when adding, which can lead to incorrect answers.

### STANDARD

##### Common Core Standard:

1.OA.C.6 - Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten; decomposing a number leading to a ten; using the relationship between addition and subtraction.
