Lesson Title: Problem Solving with Addition and Subtraction

Learning Intention: By the end of the lesson, learners should be able to select and use mental or written methods to solve two-step context problems.

Success Criteria: 1. Students can identify key information in a word problem. 2. Students can choose an appropriate addition or subtraction strategy to solve the problem. 3. Students can explain their reasoning for their chosen method.

Introduction: Begin the lesson by discussing with students the importance of being able to solve real-life problems using addition and subtraction. Show them a few examples of word problems that involve multiple steps and ask them how they would go about solving them.

Main Part of the Lesson: 1. Introduce the concept of two-step context problems and discuss strategies for solving them. 2. Provide students with a few examples of two-step context problems and work through them together as a class. 3. Give students time to work on solving similar problems independently or in small groups. 4. Circulate around the room to provide support and guidance as needed.

Plenary: Gather the students back together as a class and discuss the strategies they used to solve the problems. Ask students to share their thought processes and reasoning behind their chosen methods.

Differentiation: - Provide visual aids or manipulatives for students who may need extra support. - Offer extension activities for students who grasp the concept quickly.

Assessment Strategies: - Observe students as they work on the problems to assess their understanding and application of the strategies. - Have students explain their thinking process during the plenary to assess their ability to articulate their reasoning.

Higher Order Thinking Questions: 1. How can you check your answer to make sure it is correct? 2. Can you think of a different strategy that could be used to solve this problem? 3. How would the problem change if…? (Analyzing and evaluating)
