Lesson Plan Title:

Grade 1 Mathematics Lesson Plan: Problem Solving

Materials Needed:

  • Multiples of 10 flashcards
  • Counting blocks or beads
  • Worksheets with simple word problems
  • Mini whiteboards and markers
  • Large visual aids or posters to demonstrate problem-solving steps
  • Audio-visual equipment for showing a short instructional video (optional)

Learning Objectives:

By the end of the lesson, students will be able to:
1. Understand basic problem-solving strategies
2. Apply counting and simple arithmetic to solve word problems
3. Communicate solutions clearly


  1. Problem – A question that needs to be solved
  2. Solution – The answer to a problem
  3. Count – To determine the total number of items
  4. Add – To combine two or more numbers to get a total
  5. Subtract – To take one number away from another

Previous Learning:

Students have learned basic counting and the concept of addition and subtraction within 10. They have practiced simple arithmetic operations through various counting games and hands-on activities.

Anticipated Challenges and Solutions:

  1. Difficulty Understanding Word Problems:
  2. Solution: Use visual aids and act out scenarios to help students grasp the context.
  3. Struggling with Concentration:
  4. Solution: Break tasks into smaller parts and incorporate short, engaging activities.
  5. Variability in Skill Level:
  6. Solution: Pair students strategically, providing additional support and differentiated worksheets for varied skill levels.

Beginning Activities (4 minutes):

  1. Introduction:
  2. Greet students and introduce the lesson topic.
  3. Briefly explain what problem-solving means.
  4. Present the learning objectives in simple terms.
  5. Activate Prior Knowledge:
  6. Ask students if they remember some ways and situations where they counted or added numbers (like counting toys or sharing snacks).

Middle Activities (32 minutes):

  1. Instruction and Demonstration (10 minutes):
  2. Show a simple word problem using visual aids.
  3. Model the problem-solving process step-by-step: understanding the problem, counting, and arriving at the solution.
  4. Solve a couple of example problems together as a class, using counting blocks.
  5. Guided Practice (10 minutes):
  6. Hand out mini whiteboards and markers.
  7. Present simple word problems one at a time.
  8. Allow students to discuss and solve the problems with a partner, using counting blocks and writing their solutions on the mini whiteboards.
  9. Circulate the room, providing help and encouragement as needed.
  10. Independent Practice (10 minutes):
  11. Give each student a worksheet with several word problems to solve independently.
  12. Encourage them to use the problem-solving steps discussed (understanding, counting, solving).
  13. Observe and assist students who need help.
  14. Review (2 minutes):
  15. Quickly review a few problems from the worksheet with the class, reinforcing the problem-solving steps.

End Activities (4 minutes):

  1. Exit Ticket Activity:
  2. Ask students to solve one last word problem on a small piece of paper as their exit ticket.
  3. Collect and quickly check their understanding.

Assessment and Checks for Understanding:

  1. Observation during Guided and Independent Practice:
  2. Monitor students’ participation and accuracy of responses.
  3. Worksheet Completion:
  4. Review completed worksheets to assess comprehension.
  5. Exit Ticket:
  6. Use the exit ticket to identify students who may need additional support or practice.

Differentiation Strategies for Diverse Learners:

  1. For Struggling Learners:
  2. Provide extra one-on-one or small group support.
  3. Simplify problems or break them into more manageable parts.
  4. For Advanced Learners:
  5. Offer more challenging word problems.
  6. Encourage them to write their own word problems to solve.

Teaching Notes:

  • Emphasise a step-by-step approach to problem-solving, reinforcing the use of visuals and physical counting aids.
  • Embed frequent checks for understanding and ensure that explanations are clear and accessible for all students.
  • Adapt materials and instructions as needed to meet the needs of students with disabilities, ensuring that all students can participate effectively.

By focusing on these strategies and activities, the lesson will aim to build a strong foundation in problem-solving skills, which are crucial for future mathematical learning and daily life applications.
