Lesson Plan: Organize to Find How Many and Compare
Subject: Mathematics
Grade Level: 1
Duration: 30 Minutes
Topic: Organize to Find How Many and Compare
Learning Objectives
By the end of this lesson, students will be able to:
- Organize items into groups for counting.
- Compare quantities using terms such as "more," "less," and "equal."
Materials Needed
- Small counting objects (e.g., blocks, buttons, or tokens)
- Chart paper or a whiteboard
- Markers
- Worksheets for individual practice
- Comparison cards with symbols (more than, less than, equal to)
Lesson Outline
1. Introduction (5 minutes)
- Start by asking students what they think “organize” means.
- Explain that today they will learn how to organize groups of objects to understand how many there are and how to compare those groups.
2. Direct Instruction (10 minutes)
- Demonstration: Use a set of counting objects. Show how to organize them into two groups (e.g., 3 blocks and 5 blocks).
- Count each group out loud together as a class.
- Comparison: Introduce comparison terminology. Ask questions:
- "How many blocks are in the first group?" (3)
- "How many blocks are in the second group?" (5)
- "Which group has more?" (5 blocks)
- "Which group has less?" (3 blocks)
- "Are there any that are equal in number?" (no in this case)
- Write the comparison down on the board using symbols: 3 < 5.
3. Guided Practice (10 minutes)
- Divide students into small groups and provide them with a different set of counting objects.
- Ask each group to organize their objects into two groups and count them.
- Once counted, each group will compare their findings with the rest of the class using the vocabulary discussed.
- Circulate to assist groups and prompt comparisons.
4. Independent Practice (5 minutes)
- Hand out worksheets that include pictures of objects for students to organize, count, and compare.
- Students will complete the worksheet individually, writing down the number of items in each group and comparing them.
Closing (5 minutes)
- Review key concepts of counting and comparing.
- Invite a few students to share their findings from their worksheets.
Homework Assignment
Task
- Find 10 small items at home (like coins, buttons, or toys). Organize them into two groups of your choice.
- Count how many are in each group and write the numbers down.
- Compare the two groups using comparison symbols and write a sentence to explain your findings (e.g., "Group A has more than Group B.")
Example:
- Group A: 4 buttons
- Group B: 6 buttons
- Write: "4 < 6. Group A has less than Group B."
Correct Answers (for teacher reference)
- Students will vary in their groupings, but expected comparisons could be:
- 2 vs 8 (2 < 8)
- 5 vs 5 (5 = 5)
- 3 vs 1 (3 > 1)
Assessment
- Observe student participation during group activities and independent practice.
- Review homework for understanding of organizing and comparing quantities.
This concludes your 30-minute mathematics lesson for Grade 1 on organizing to find how many and compare!
