LESSON INSTRUCTION
INTRODUCTION
-
- Review the concept of subtraction with students and introduce the minus sign (-) as the symbol for subtraction.
- Explain that subtraction word problems are stories that involve taking away or finding the difference between two numbers.
Note: The introduction should capture students' attention, establish the purpose of the lesson, and set the stage for the learning activities that will follow.
INSTRUCTION
- Present the example problem: "Farmer Williamson has 8 pineapples to sell at the market. 3 pineapples sell. How many pineapples are left?"
- Model how to use manipulatives to solve the problem and write the number sentence: "8 - 3 = 5."
- Discuss the process of solving subtraction word problems and writing number sentences.
GUIDED PRACTICE
- Provide students with a worksheet containing subtraction word problems.
- Work through the problems together as a class, using manipulatives to solve the problems.
- Encourage students to write number sentences to represent each problem.
INDEPENDENT PRACTICE
-
- Provide students with another worksheet of subtraction word problems to complete independently.
- Circulate around the room to provide support and guidance as needed.
HOMEWORK
- Encourage students to create their own subtraction word problem and illustrate it with drawings or manipulatives at home.
- Instruct students to write a number sentence to represent the problem.
Note: Homework should be optional and not graded. It is important to provide a balance between schoolwork and home life, and to ensure that students have enough time to rest and engage in other activities.
EXIT TICKET
- Provide each student with a small whiteboard and marker.
- Instruct students to write a number sentence that represents a subtraction word problem.
- Collect and review the whiteboards to assess students' understanding.
ASSESSMENT
- Ask students to share a subtraction word problem they solved and how they solved it.
- Use their responses to assess their understanding of subtraction word problems.
Note: Summative assessment is performed at the end of a learning period and typically consists of a problem set of at least 10 questions to measure a student's proficiency level.
CLOSURE
- Review the key concepts of subtraction word problems and solving them using manipulatives and number sentences.
- Encourage students to continue practicing subtraction word problems at home and in future lessons.
EXTENSION
- Students can practice solving subtraction word problems with numbers up to 10 or 20.
- Students can create their own subtraction word problems and exchange them with classmates to solve.
INTERVENTION
- For students who need extra support, provide one-on-one or small group instruction with additional subtraction word problems and manipulatives.
- For students who struggle with fine motor skills, larger and easier-to-grasp manipulatives can be used.
- For students who need visual aids or diagrams, provide graphic organizers to help them understand the concept of subtraction word problems.
VIDEOS
No Video Available
TEACHING TIPS
- Use real-life examples: Incorporate real-life scenarios when presenting subtraction word problems to help students make connections to their own experiences.
- Encourage peer collaboration: Allow students to work in pairs or small groups during guided practice, fostering collaboration and discussion while solving problems.
- Praise effort and progress: Encourage and praise students' effort and progress during the lesson to boost confidence and motivation.
STUDENT MISCONCEPTIONS
- Subtraction always results in a smaller number: Some students may think that subtraction will always result in a smaller number, not realizing that when the minuend and subtrahend are equal, the difference is zero.
- Reversing numbers in the number sentence: Students may incorrectly assume that the order of numbers in a subtraction number sentence does not matter, leading to incorrect answers.
- Confusing subtraction with addition: Young learners may confuse subtraction with addition due to their limited exposure to mathematical operations. Reinforce the differences between the two operations throughout the lesson.
STANDARD
Common Core Standard:
K.OA.A.1 Part 1 - Represent addition with objects, fingers, mental images, drawings, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.
