Solve Subtraction Word Problems (up to 10)
Prerequisite Skill
Materials and Preparation
- TeachTastic Worksheet Pack: Features visual aids depicting farmyard scenes, subtraction stories, and hands-on activity suggestions.
- Visual Aids: Pictures of chickens in a coop and chickens in a yard for demonstration.
Learning Objectives
Students will be able to solve subtraction word problems by understanding the concept of "taking away" using scenarios with numbers up to 10.
Introduction
Begin with a lively discussion about farm animals, focusing on chickens. Ask students if they have seen a chicken coop and explain how sometimes chickens are inside the coop and sometimes they are outside.
Explicit Instruction/Teacher modeling
Learn with an example:
- Draw or display pictures of chickens in a coop and chickens in a yard. Talk the students through multiple versions of inside and taking away to move outside.
- Question: "Read the story. There are 8 chickens in the coop. Then, 6 chickens go outside. Subtract to find how many chickens stay in the coop. 8−6="
- Solution: "Count the chickens that stay. Only 2 chickens stay. 8−6=2"

Guided Practice
Provide students with the "Subtraction Scenarios" worksheet, which includes various subtraction word problems. These problems use farmyard settings to contextualize subtraction as the students work through them together.
Independent Practice
Students will tackle the "Farmyard Math Mysteries" worksheet on their own, solving subtraction word problems that require them to visualize and subtract numbers up to 10, using farmyard scenarios for engaging context.
Differentiation
Support
- For students needing extra help, use physical counters like beans or small toys to represent the chickens, facilitating a tangible understanding of subtraction.
- Encourage peer learning by pairing students to solve problems together, discussing their thought process.
Extension
- Introduce mixed operations word problems that combine both addition and subtraction to challenge students.
- Create a mini-farm setup in the classroom where students can physically move objects to simulate subtraction problems.
Assessment
Assess student understanding through their completion of worksheets, participation in discussions, accuracy of exit tickets, and creative homework assignments, focusing on their ability to solve subtraction word problems.
Review and closing
Conclude by reviewing key concepts and discussing how subtraction helps us understand how many are left when something is taken away. Highlight successful problem-solving strategies used during the lesson.
Misconceptions
- Students may confuse subtraction with addition, thinking the number should increase rather than decrease. Reinforce the concept that subtraction means "taking away."
- Some students might struggle with the abstract concept of subtraction; using tangible objects or drawing pictures can help solidify this concept.
