Addition Sentences for Equal Groups – Relate addition to multiplication – Objective: Write addition sentences – Create sentences showing equal groups adding to 25 – Equal groups sum up to 25 – Example: 5 groups of 5 apples is 5 + 5 + 5 + 5 + 5 – Practice with examples – Use objects like fruits or toys to visualize | This slide introduces the concept of writing addition sentences for equal groups as a foundation for understanding multiplication. Start by explaining how addition is used to count the total number of items in equal groups. The objective is for students to be able to write their own addition sentences that represent equal groups, with the total sum not exceeding 25. Use concrete examples, such as groups of apples or toys, to help students visualize the concept. Encourage them to think of their own examples and write addition sentences for them. Provide practice opportunities with different numbers of groups and items to solidify their understanding.

Understanding Equal Groups – Equal groups have identical counts – Example: 3 groups of 4 apples – 3 groups with 4 in each makes 3 x 4 – Visualize equal groups with images – Use pictures to show groups of objects – Practice creating groups with sums to 25 – Combine smaller groups to total 25 items | This slide introduces the concept of equal groups as a foundation for understanding multiplication. Start by explaining that equal groups contain the same number of objects. Use the example of 3 groups of 4 apples to illustrate this point. Provide visual aids, such as images or drawings, to help students visualize what equal groups look like. Encourage students to draw their own examples. Finally, engage the class in an activity where they create their own equal groups that add up to a sum of 25, reinforcing the connection between addition and multiplication. This will prepare them for understanding how multiplication is repeated addition.

Writing Addition Sentences for Equal Groups – Addition sentences represent totals – Example: Grouped apples add up – Like 4 apples + 4 apples + 4 apples = 12 apples – Practice writing sentences together – We’ll create an addition sentence as a class – Sums up to 25 – Ensure the total sum does not exceed 25 | This slide introduces the concept of writing addition sentences for equal groups, which is a foundational skill for understanding multiplication. Start by explaining that addition sentences are a way to find the total number of objects when they are grouped together. Use the example provided to show how repeated addition of the same number of objects (like apples) can be expressed as an addition sentence. During the practice activity, engage the class in creating a new addition sentence together, ensuring that the sum does not exceed 25. This will help students grasp the concept of equal groups and prepare them for learning multiplication as repeated addition.

From Addition to Multiplication – Multiplication: fast track for addition – Example: 3 groups of 4 apples – Instead of 4 + 4 + 4, we write 3 x 4 = 12 – Addition to multiplication conversion – If we had 4 + 4 + 4 = 12, it becomes 3 x 4 = 12 – Practice with sums up to 25 – Find other groups that add up to 25, then write as multiplication | This slide is aimed at helping third-grade students understand the concept of multiplication as a quicker method of adding equal groups of numbers. Start by explaining that multiplication is simply adding the same number over and over, and it’s a faster way than writing out the full addition sentence. Use concrete examples like groups of apples to illustrate this point. Show them how an addition sentence like 4 + 4 + 4 can be turned into a multiplication sentence 3 x 4. Then, encourage the students to practice this skill by finding groups of numbers that add up to 25 and writing them as multiplication sentences. This will help solidify their understanding of the relationship between addition and multiplication.

Let’s Practice Together: Creating Equal Groups – Create equal groups using objects – Write an addition sentence for groups – Example: 4 groups of 5 apples is 5+5+5+5 – Determine total sum up to 25 – Share your findings with the class – Tell us: How many groups and items per group? | This activity slide is designed to help students apply their understanding of addition in the context of equal groups, which is a foundational concept for understanding multiplication. Students will use tangible objects to create equal groups and then write corresponding addition sentences that sum up to 25. This hands-on approach reinforces the concept of repeated addition as a precursor to multiplication. For the activity, provide students with a variety of small objects to group and count. Encourage creativity in how they form groups. After writing their addition sentences, students will share how many groups they made and how many objects are in each group, fostering communication skills and peer learning. Possible variations of the activity could include using different objects, creating groups of varying sizes, or challenging students to find multiple grouping combinations that add up to 25.

Class Activity: Addition Sentences Game – Pair up and roll the dice twice – Form equal groups from dice numbers – Write an addition sentence – If you roll a 4 and a 3, write: 4 + 4 + 4 = 12 – Challenge: Convert to multiplication – The same numbers form the multiplication sentence: 3 x 4 = 12 | This interactive game is designed to help students understand the relationship between addition and multiplication through hands-on activity. Students will work in pairs to roll dice twice, using the numbers to create equal groups and then write corresponding addition sentences. The challenge portion encourages students to think critically about how these addition sentences can be represented as multiplication sentences. For example, if a student rolls a 5 and a 3, they would write ‘5 + 5 + 5 = 15’ and then convert it to ‘3 x 5 = 15’. Provide guidance and ensure each pair has dice. Offer additional support to students who may struggle with forming the sentences or understanding the multiplication concept.

Review and Reflect: Addition Sentences for Equal Groups – Recap: Addition sentences represent equal groups – Connection between addition and multiplication – Multiplication is repeated addition of the same number – Examples of equal groups at home – Organizing toys in sets or sharing snacks equally – Understanding sums up to 25 – Practice with different group sizes that add up to 25 | This slide aims to consolidate the students’ understanding of how addition sentences can represent equal groups and how this concept is a stepping stone to understanding multiplication as repeated addition. Encourage students to reflect on what they’ve learned by thinking about how they group items equally in their daily lives, such as when sharing or organizing. This real-world connection reinforces their learning. Ask them to come up with their own examples where they make equal groups that sum up to 25, which will help them grasp the concept of multiplication and prepare them for more complex math problems. Provide guidance on how to form different group sizes that add up to 25 to enhance their understanding.

Homework Challenge: Grouping and Addition – Find items to make equal groups at home – Write addition sentences for your groups – Example: 4 pencils + 4 pencils + 4 pencils = 12 pencils – Ensure sums do not exceed 25 – Bonus: Convert to multiplication sentences – If you have 3 groups of 4 pencils, that’s 3 x 4 = 12 | This homework task is designed to reinforce the concept of equal groups as a foundation for understanding multiplication. Students should gather small items around their home to create equal groups and then write addition sentences that sum up to 25 or less. This exercise will help them visualize the concept of addition as the process of combining equal groups. The bonus task encourages students to make the connection between repeated addition and multiplication, which is a key concept in understanding how multiplication works. For the teacher: be prepared to discuss different strategies for forming groups and writing sentences, and offer examples for clarity. Encourage creativity in finding items to group and ensure students understand the limit of 25 for the sum.
