Sum: The result of adding two or more numbers.
Cube Model: A visual representation using cubes to show addition.
Match Models to Addition Sentences
Prerequisite Skill
Materials and Preparation
- TeachTastic Worksheet Pack for Addition Sentences
- Sets of colored cubes (e.g., yellow and purple)
- Whiteboard and markers
- Example cube models
- Student notebooks and pencils
Learning Objectives
- Students will be able to identify addition sentences that match given cube models.
- Students will demonstrate understanding of addition sentences up to 10 by creating and matching cube models.
- Students will explain their reasoning for matching cube models to addition sentences.
Introduction
Begin by explaining the concept of addition and how it involves combining numbers to find the total. Introduce cube models as a tool to visualize addition. Show a simple example: "Here we have 3 yellow cubes and 1 purple cube. How many cubes do we have in total?" (4 cubes).
Explicit Instruction/Teacher modeling
Write the addition sentence "3 + 1 = 4" on the whiteboard. Show the corresponding cube model with 3 yellow cubes and 1 purple cube. Explain how the cubes represent the numbers in the addition sentence. Repeat this with a few more examples to reinforce the concept.
Guided Practice
Hand out the Guided Practice worksheet from the TeachTastic Worksheet Pack. Work through the first few problems together, matching addition sentences with cube models. Use sets of cubes to physically create the models and verify the addition sentences.
Independent Practice
Students will complete the Practice worksheet independently, where they will match addition sentences with cube models. Provide sets of cubes for students to use as they work through the problems.
Differentiation
Support
- Visual Aids: Use posters or charts with addition sentences and corresponding cube models.
- Peer Assistance: Pair students who grasp the concept well with those needing extra help.
Extension
- Real-Life Application: Ask students to find objects at home to create their own addition sentences and models.
- Challenge Problems: Provide addition sentences with sums greater than 10 for advanced students to match with cube models.
Assessment
Use the Assessment worksheet from the TeachTastic Worksheet Pack to evaluate students' understanding. Ensure they can accurately match addition sentences with cube models and explain their reasoning.
Review and closing
Summarize the key points of the lesson, emphasizing the importance of visualizing addition with cube models. Address any common misconceptions, such as confusing the order of cubes in a model. Allow students to ask questions and share their observations about the lesson.
Misconceptions
- Believing the order of cubes affects the sum: Clarify that 3 yellow cubes and 1 purple cube represent the same sum as 1 yellow cube and 3 purple cubes.
- Thinking that different colors of cubes mean different values: Emphasize that all cubes, regardless of color, represent the same value in an addition sentence.
