Lesson Plan for Unit 6, Lesson 16: Introduction to Basic Addition
Subject
Mathematics
Grade Level
1st Grade
Duration
30 Minutes
Objective
Students will be able to understand and solve basic addition problems using visual aids and manipulatives.
Materials Needed
- Counting blocks or cubes (10 per student)
- Whiteboard and markers
- Number line (printed or drawn)
- Worksheets with simple addition problems
- Stickers for rewards
Introduction (5 Minutes)
- Engagement: Begin the lesson by asking students if they have ever shared candies or toys with a sibling or friend. This will engage them in thinking about the concept of addition as combining groups.
- Direct Instruction: Explain that today’s lesson will focus on adding numbers together to find out how many we have in total. Introduce the term "addition" and explain it using a simple equation (e.g., 2 + 3).
Guided Practice (10 Minutes)
- Demonstration: Use counting blocks to show an example of addition. For instance, place 2 blocks on the table and then add 3 more blocks. Count all the blocks together (2 + 3 = 5).
- Whole Class Activity: Have students use their own counting blocks to replicate the demonstration. Ask them to create their own addition problems using a set number of blocks.
- Example: “If you have 4 blocks and add 1 more, how many blocks do you have?”
Independent Practice (10 Minutes)
- Worksheet Distribution: Hand out worksheets that have simple addition problems with pictures and numbers to help students visualize.
- Silent Work: Allow students to work on these addition problems independently. Walk around the room to provide help where needed.
- Encourage: Remind students to use counting blocks if they are having trouble with a problem.
Closing (5 Minutes)
- Review: Gather the class and review the problems from the worksheets. Ask different students to share their answers and explain how they got their totals.
- Interactive Game: End with a quick addition game. Call out a simple addition problem, and have students raise their hands when they know the answer.
- Rewards: Hand out stickers to students who participated and gave correct answers to reinforce positive behavior and participation.
Assessment
- Observe students during guided practice to assess their understanding.
- Review completed worksheets for accuracy.
- Use answers from the interactive game to gauge class understanding.
Homework (Optional)
- Students can take home a small number of items (like coins or snacks) and practice creating their own simple addition problems, drawing and writing them down to share in the next class.
