Subtract with Pictures (up to 5)
Prerequisite Skill
Materials and Preparation
- TeachTastic Worksheet Pack for Subtracting with Pictures (up to 5)
- Whiteboard and markers
- Picture cards or printed images of objects (cars, robots, etc.)
- Crayons or markers for crossing out pictures
Learning Objectives
- Students will understand the concept of subtraction as taking away.
- Students will be able to subtract numbers up to 5 using pictures.
- Students will solve subtraction problems by crossing out pictures to find the remaining quantity.
Introduction
Begin by showing the class a picture of three cars. Explain that subtraction means taking away some of the cars and seeing how many are left. Cross out two of the cars in the picture and ask the students how many cars are left. Write the subtraction equation 3 − 2 = 1 on the board and explain that when we start with 3 cars and take away 2, we are left with 1 car.
Explicit Instruction/Teacher modeling
Demonstrate another example using a picture of five apples. Cross out three apples and ask the students how many apples are left. Write the subtraction equation 5 − 3 = 2 on the board. Explain each step: start with the total number of apples, cross out the number being subtracted, and count the remaining apples to find the answer.

Guided Practice
Hand out worksheets from the TeachTastic Worksheet Pack for Subtracting with Pictures (up to 5). Guide the students through a few problems on the worksheet, solving them together as a class. Encourage students to cross out the pictures and count the remaining objects to find the answer. Walk around the room to provide assistance and ensure understanding.
Independent Practice
Allow students to complete the remaining problems on the worksheet independently. Remind them to cross out the pictures and count what’s left to solve each subtraction problem. Provide support to students who need extra help.
Differentiation
Support
- Provide one-on-one or small group support for students who struggle with crossing out pictures and counting the remaining objects.
- Use manipulatives like counters or blocks to help students visualize the subtraction process.
Extension
- Challenge students who have mastered subtraction with numbers up to 5 to solve subtraction problems with numbers up to 10 using pictures.
- Introduce word problems that involve subtraction and require students to draw pictures to solve them.
Assessment
Evaluate students' worksheets and exit tickets to check for understanding and mastery of the lesson objectives. Pay special attention to their ability to correctly cross out pictures and count the remaining objects.
Review and closing
Review the key points of the lesson, emphasizing that subtraction means taking away and seeing what is left. Address any common misconceptions and ensure that students are clear on the process. Allow students to ask questions and share their observations.
Misconceptions
- Thinking that subtraction always makes numbers bigger.
- Confusing the number to be crossed out with the total number.
- Not accurately counting the remaining objects.
