Lesson Plan Title:

Grade 1 Mathematics Lesson Plan: Developing Number Sense

Materials Needed:

  • Number cards (1-20)
  • Counting objects (such as beads, buttons, or plastic counters)
  • Whiteboard and markers
  • Worksheets with number lines and simple arithmetic problems
  • Interactive number games on a tablet/computer (if available)
  • Flashcards with numbers and dots

Learning Objectives:

  • Understand and recognise numbers from 1 to 20.
  • Develop counting skills and the ability to count objects.
  • Begin to understand basic addition and subtraction.
  • Identify numbers before, after, and in between given numbers.

Vocabulary:

  1. Number: Symbols used to represent quantity (e.g., 1, 2, 3).
  2. Count: To determine the total number of items in a group.
  3. Addition: The process of finding the total or sum by combining numbers.
  4. Subtraction: The process of finding the difference between numbers by taking one away from another.
  5. Number Line: A line marked with numbers at evenly spaced intervals.

Previous Learning:

Students have learned to identify numbers 1-10 and have practised counting objects up to 10. They have also been introduced to the concept of more and less through everyday activities.

Anticipated Challenges and Solutions:

  • Challenge: Some students may struggle with recognising numbers out of sequence.
  • Solution: Use number cards and number lines frequently.
  • Challenge: Difficulty in keeping track while counting objects.
  • Solution: Encourage the use of fingers or small counting aides.
  • Challenge: Confusion between addition and subtraction.
  • Solution: Use visual aids and simple story problems to illustrate each concept clearly.

Beginning Activities (4 minutes):

  1. Introduce Learning Objectives: Explain what students will be learning today – number recognition, counting, and basic addition and subtraction.
  2. Quick Warm-Up Activity: Use flashcards to review numbers 1-10. Ask students to call out the number they see.

Middle Activities (32 minutes):

  1. Direct Instruction (10 minutes):
  2. Teach students how to count from 1 to 20 using a number line.
  3. Show how to use counting objects to physically count up to 20.

  4. Introduce basic addition using small groups of objects (e.g., 2 beads + 3 beads).

  5. Guided Practice (10 minutes):

  6. Distribute number cards (1-20) and counting objects. Have students practice counting objects to match the numbers on their cards.

  7. Use a whiteboard to demonstrate numbers that come before, after, or in between given numbers on the number line.

  8. Independent Practice (12 minutes):

  9. Provide worksheets with number lines and simple arithmetic problems (e.g., 1+1, 2+3). Have students complete these on their own.
  10. Facilitate interaction with interactive number games (if available) to reinforce counting and arithmetic skills.

End Activities (4 minutes):

  1. Exit Ticket: Have students complete a quick activity where they must match numbers to the correct number of objects. Collect this activity as they leave to assess understanding.

Assessment and Checks for Understanding:

  • Observation during guided practice.
  • Correct completion of worksheets.
  • Accuracy of exit ticket activities.
  • Participation in interactive games.

Differentiation Strategies for Diverse Learners:

  • Scaffolding: Pair struggling students with peers who can assist. Provide additional visual aids, such as counting charts.
  • Extension: Encourage advanced learners to solve more complex problems or count beyond 20 with higher number cards.

Teaching Notes:

  • Purpose: This lesson builds a foundational understanding of number sense, crucial for future arithmetic skills.
  • Educational Value: Understanding numbers and basic arithmetic forms the basis for all future mathematics education.
  • Tips for Effective Delivery: Ensure the lesson is interactive and engaging. Use various methods (visual, tactile, auditory) to cater to different learning styles.
  • Accessibility Considerations: Prepare enlarged number cards or manipulatives for students with visual impairments. Consider using tactile counting objects for sensory engagement.

By following this structured plan, students will develop solid number sense, essential for their ongoing mathematical learning journey.
