Learners can show ways to complete addition sentences with "and" and "is".

###### EXTENSION SKILL

- Students will be able to read addition models and identify the correct addition sentence that matches.
- Students will be able to demonstrate their understanding of addition by creating their own addition models.

### LESSON INSTRUCTION

###### INTRODUCTION

- Display an addition sentence on the whiteboard, such as "3 + 2 = 5."
- Ask students to read the sentence aloud and explain what it means.
- Explain to students that they will be learning how to select a cube model that matches an addition sentence.

###### INSTRUCTION

- Show students an addition sentence card and a cube model card.
- Model how to read the addition sentence and count the cubes to find the answer.
- Demonstrate how to select the cube model that matches the addition sentence.
- Repeat with several examples.

###### GUIDED PRACTICE

- Provide each student with an addition sentence card and a container of unifix cubes.
- Instruct students to read the addition sentence and use the unifix cubes to find the answer.
- Ask students to select the cube model that matches the addition sentence and place it next to the card.
- Circulate around the room to provide support and guidance as needed.

###### INDEPENDENT PRACTICE

- Provide each student with a set of addition sentence cards and a set of cube model cards.
- Instruct students to match the addition sentence cards with the cube model cards.
- Encourage students to use the unifix cubes to count and find the answer before selecting the cube model card.
- Circulate around the room to provide support and guidance as needed.

###### HOMEWORK

- Ask students to create their own addition sentence and draw a cube model that matches.
- Encourage students to share their addition sentence and cube model with the class the next day.

Note: Homework should be optional and not graded. It is important to provide a balance between schoolwork and home life, and to ensure that students have enough time to rest and engage in other activities.

###### EXIT TICKET

- Provide each student with an addition sentence card and a container of unifix cubes.
- Instruct students to read the addition sentence and use the unifix cubes to find the answer.
- Ask students to select the cube model that matches the addition sentence and place it next to the card.

###### ASSESSMENT

- Ask students to share one addition sentence they matched with a cube model and explain how they found the answer.

###### CLOSURE

- Review with students what they learned about reading addition sentences and matching cube models.
- Encourage students to continue practicing with addition sentences and cube models.

###### EXTENSION

- Students can create their own addition sentences and cube model cards for a classmate to match.
- Students can use larger numbers to create addition sentences and cube models.

###### INTERVENTION

- Provide manipulatives or a number line for students who struggle with counting to help them find the answer.
- For students who need extra support, provide additional practice with simpler addition sentences and cube models.

###### VIDEOS

No Video Available

### TEACHING TIPS

- Use a variety of manipulatives to help students visualize and understand addition.
- Encourage students to explain their thinking and reasoning when matching addition sentences to cube models.
- Provide opportunities for students to practice using addition in real-world scenarios, such as counting money or sharing items among friends.

### STUDENT MISCONCEPTIONS

- Students may think that the plus sign (+) always means to add, rather than recognizing that it represents addition specifically.
- Students may struggle with the concept of counting on, where they start with the larger number and count up to find the sum.
- Students may incorrectly match addition sentences to cube models by simply counting the total number of cubes, rather than understanding the relationship between the two numbers being added.

### STANDARD

##### Common Core Standard:

1.OA.B.3 - Apply properties of operations as strategies to add and subtract.2 Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.)
