Lesson Plan: Number Pairs that Add to 10
Subject
Mathematics
Grade Level
Reception / Kindergarten
Duration
30 minutes
Learning Objectives
By the end of this lesson, students will be able to:
- Identify and create number pairs that add up to 10.
- Understand the concept of addition as combining two numbers.
Materials Needed
- Whiteboard and markers
- Counting blocks or small manipulatives (e.g., buttons, beads)
- Worksheets with number pairing activities
- Colorful number cards (0-10)
Lesson Outline
Introduction (5 minutes)
- Greeting and Warm-Up: Welcome the students and engage them with a quick number song to set a fun and positive tone for the lesson.
- Discussion: Ask students if they know what it means to add numbers together. Explain that addition is when we combine two groups to find out how many we have altogether.
Direct Instruction (10 minutes)
- Introduce Number Pairs: Write the number 10 on the whiteboard. Tell students that today they will learn about pairs of numbers that add up to 10.
- Demonstration: Use counting blocks to demonstrate. For example, show 4 blocks and ask how many more blocks are needed to reach 10 (6 blocks). Write this as an equation: 4 + 6 = 10.
- Explore More Pairs: Continue demonstrating with different pairs, such as 2 + 8, 3 + 7, 5 + 5, and discuss the process aloud as you go.
Guided Practice (10 minutes)
- Interactive Game:
- Distribute colorful number cards to students.
- Ask students to find a partner and make groups of numbers that add up to 10.
- Encourage them to use their manipulatives to justify their answers (e.g., “Look, I have 3 blocks and my partner has 7 blocks. Together we have 10!”).
Independent Practice (5 minutes)
- Worksheet Activity: Hand out worksheets with different exercises:
- Fill in the blanks with the correct numbers to make pairs that add to 10.
- Draw circles to represent number pairs that sum to 10.
Closure (5 minutes)
- Review: Gather the students and ask them to share some number pairs they made. Write their answers on the whiteboard.
- Reinforcement: Summarize the importance of number pairs that add up to 10 and encourage students to keep practicing.
Homework Assignment
Provide students with a simple homework task that reinforces the lesson:
Homework Tasks
- Find and write down 5 pairs of numbers that add up to 10. (Examples: 0+10, 1+9, 2+8, 3+7, 4+6)
- Use objects at home (e.g., toys or fruit) to make pairs of 10 altogether and take a picture of one of the pairs.
Homework Answers
- Pair examples for teachers' reference:
- 0 + 10 = 10
- 1 + 9 = 10
- 2 + 8 = 10
- 3 + 7 = 10
- 4 + 6 = 10
- (Students' examples may vary; ensure they add up to 10.)
Assessment
- Observe participation during the group activity.
- Review worksheets for understanding during the guided practice.
- Check homework for correct understanding of number pairs adding to 10.
This lesson plan aligns with Common Core State Standards for Mathematics, focusing on counting and cardinality, specifically the addition of whole numbers within 10.
