Determine What Addition Sentence the Model Shows

Prerequisite Skill

Use Cubes to Add (sums up to 10)

Materials and Preparation

  • Connecting cubes (enough for each student to have at least 20 cubes)
  • Whiteboard and markers
  • Worksheet pack including guided practice, independent practice, exit tickets, homework, and assessment

Learning Objectives

  • Students will be able to understand and perform addition within 10.
  • Students will be able to match addition sentences to corresponding object sets using connecting cubes.

Introduction

Begin by asking students if they know what addition is. Explain that addition means putting numbers together to make a bigger number. Show an example on the board: "If I have 3 apples and get 2 more, how many apples do I have in total?" Demonstrate using real or drawn apples, and write the addition sentence 3 + 2 = 5.

Explicit Instruction/Teacher modeling

Explain that today, we will use connecting cubes to help us understand addition. Show a set of 3 connecting cubes and another set of 2 connecting cubes. Connect them together and count the total number of cubes. Write the addition sentence 3 + 2 = 5 on the board. Repeat with different numbers, ensuring students understand how to count and connect the cubes.

Guided Practice

Distribute a guided practice worksheet to each student. This worksheet will have several sets of objects on one side and corresponding addition sentences on the other side. Instruct students to draw lines from each set of objects to the correct addition sentence. Walk around the room to provide assistance and ensure students are matching correctly. After completing the worksheet, review the answers as a class, discussing any mistakes.

Independent Practice

Students will be given models on the worksheet to match to a given addition sentence. This is multiple choice, starting from 2 options and graduating to 4 for a greater level of challenge. Instruct students to circle the correct object set that matches each addition sentence. Monitor and provide help as needed. After students have completed the matching, have them check their answers with a partner.

Differentiation

Support

  • Pair struggling students with a buddy for additional practice.
  • Use visual aids and manipulatives for students who need more concrete examples.
  • Offer extra practice worksheets for home use.

Extension

  • Provide addition problems using numbers up to 20.
  • Introduce subtraction with connecting cubes.
  • Use story problems to apply addition in real-world scenarios.

Assessment

Use the assessment worksheet included in the worksheet pack. This worksheet will have addition sentences that students need to solve using drawings or pictures of various objects. Review their answers to assess understanding and identify any areas needing further review.

Review and closing

Review the key points of the lesson. Address common misconceptions such as mixing up the order of numbers or miscounting the cubes. Ensure clarity by going over any problem areas and allowing students to ask questions. Encourage students to share their observations or curiosities about addition.

Misconceptions

  1. Students may think that the order of numbers in an addition sentence affects the sum (e.g., 3 + 2 is different from 2 + 3).
  2. Students might miscount the total number of cubes when combining sets.
