Addition: The process of finding the total number of items when two or more groups are put together.

Sum: The result of adding two or more numbers.

Zero: A number that represents none or nothing; adding zero to a number does not change the number.

Adding with Zero

Add with 0

Prerequisite Skill

Add with Pictures, Focusing on Sums Up to 10

Materials and Preparation

  • Worksheets from "Add with 0" worksheet pack
  • Whiteboard and markers
  • Counters or manipulatives
  • Pencils and erasers

Learning Objectives

  • Students will be able to understand and apply the concept of adding zero to a number.
  • Students will be able to solve addition problems involving zero.

Introduction

Start by asking students if they have ever noticed what happens when they add zero to a number. Use simple examples on the whiteboard, such as 5 + 0 and 0 + 7. Explain that adding zero to any number does not change the number, and provide a few more examples.

Explicit Instruction/Teacher modeling

Explain that today we will learn more about adding zero to different numbers. Demonstrate on the whiteboard how adding zero works with different numbers. For instance, write 8 + 0 and ask students what the answer is, reinforcing that 8 remains 8. Repeat with other numbers like 3 + 0, 0 + 6, etc.

Guided Practice

Distribute the domino cards included in the worksheet pack and have students cut them out with scissors. Organize students into small groups and instruct each group to shuffle their domino cards and place them in a pile face down. Each student will draw a card, construct the addition problem shown on the domino (e.g., if the domino shows 3 and 0, they write 3 + 0 = 3), and solve it on their guided practice worksheet. Walk around to assist and encourage students, ensuring they understand that the sum does not change when zero is added.

Independent Practice

Provide students with a worksheet that contains a variety of addition problems with zero, such as 4 + 0, 9 + 0, and 1 + 0. Have students solve these problems independently, using counters if necessary. Encourage students to write out the addition sentences and sum for each problem.

Differentiation

Support

  • Use visual aids like counters or number lines.
  • Pair students who might struggle with peers who grasp the concept well.
  • Offer extra practice sheets with additional problems.

Extension

  • Challenge students with word problems that involve adding zero.
  • Introduce problems where students identify which addend is zero (e.g., ____ + 0 = 5).
  • Explore the concept of zero in subtraction for advanced students.

Assessment

Students will complete an assessment worksheet where they solve a series of addition problems involving zero. The assessment will include both numerical problems and simple word problems. Evaluate students' understanding based on their accuracy and ability to explain the concept.

Review and closing

Review the main idea that adding zero to a number does not change the number. Address any common misconceptions, such as thinking that zero changes the number it is added to. Allow students to ask questions and share what they learned. Summarize the lesson by reiterating the special property of zero in addition.

Misconceptions

  1. Zero changes the number: Clarify that zero means nothing is added, so the number stays the same.
  2. Zero is a negative number: Explain that zero is neither negative nor positive; it simply represents none.
