Lesson Plan: Skip Counting by 2s, 5s, and 10s
Subject: Mathematics
Grade Level: 2
Duration: 30 minutes
Objectives
By the end of this lesson, students will be able to:
- Understand the concept of skip counting.
- Skip count by 2s, 5s, and 10s accurately.
- Apply skip counting in practical scenarios.
Materials Needed
- Whiteboard and markers
- Skip counting number charts (2s, 5s, and 10s)
- Counting manipulatives (e.g., blocks, counters)
- Worksheet for practice problems
- Interactive counting game (if technology permits)
Common Core Standards
- CCSS.MATH.CONTENT.2.OA.B.2: Add and subtract within 20 to solve word problems.
- CCSS.MATH.CONTENT.2.NBT.A.2: Count within 1000; skip-count by 5s, 10s, and 100s.
Lesson Outline
Introduction (5 minutes)
- Engagement: Begin with a brief review of counting by 1s. Ask students to count from 1 to 10 together as a class.
- Introduction to Skip Counting: Explain that today they will learn a faster way to count using skip counting. Define skip counting as counting by numbers other than one.
Direct Instruction (10 minutes)
-
Skip Counting by 2s:
- Demonstrate on the whiteboard:
- Start with 2, then 4, 6, 8, 10...
- Discuss the pattern: Add 2 each time.
- Use manipulatives to visually represent counting by 2s (groups of 2).
-
Skip Counting by 5s:
- Continue the demonstration:
- Start from 5, then 10, 15, 20, 25...
- Discuss the pattern: Add 5 each time.
- Engage students with manipulatives—arranging them in groups of 5.
-
Skip Counting by 10s:
- Final demonstration:
- Start from 10, then 20, 30, 40, 50...
- Discuss the pattern: Add 10 each time.
- Use a counting chart and highlight the numbers.
Guided Practice (10 minutes)
-
Group Activity:
- Divide students into small groups.
- Each group will use the manipulatives to create skip counting patterns on their desks.
- Students will work together to write the sequences on their individual whiteboards.
-
Class Participation:
- Ask selected groups to share their skip counting sequences with the class.
- Encourage the class to clap or cheer as they correct and confirm sequences together.
Independent Practice (5 minutes)
- Worksheet Activity:
- Hand out a worksheet with problems that require students to fill in the missing numbers in skip counting sequences for 2s, 5s, and 10s.
- Circulate the room to provide assistance where needed.
Closing (5 minutes)
- Review: Recap what was learned about skip counting by 2s, 5s, and 10s.
- Exit Ticket: Have students write down one thing they learned about skip counting and the table they found easiest (2s, 5s, or 10s).
- Preview of Next Lesson: Briefly mention that the next class will build on skip counting in relation to addition and subtraction.
Assessment
- Observe students during guided practice to evaluate their understanding.
- Review completed worksheets to assess their ability to skip count correctly.
- Collect exit tickets to gauge individual students' comprehension and engagement.
Modifications
- For advanced learners: Offer challenges that include skip counting by 3s or extending sequences beyond 100.
- For struggling learners: Provide additional manipulatives and one-on-one support during independent practice.
This lesson plan aims to create a fun and interactive environment for Grade 2 students while developing their foundational skills in skip counting.
