Lesson Plan: Different Strategies for Solving Multiplication Facts
Grade Level: 3
Duration: 30 Minutes
Subject: Mathematics
Topic: Different Strategies for Solving Multiplication Facts
Objective
Students will learn and practice various strategies for solving multiplication facts, including skip counting, grouping, using arrays, and the commutative property.
Materials Needed
- Whiteboard and markers
- Multiplication flashcards
- Array templates (grid paper)
- Manipulatives (counters or blocks)
- Worksheets for practice
- Homework assignment sheet
Introduction (5 minutes)
- Begin with a brief review of multiplication as repeated addition.
- Ask students to recall some multiplication facts they already know.
- Introduce the lesson's objective: exploring different strategies for solving multiplication facts.
Direct Instruction (10 minutes)
-
Skip Counting
- Demonstrate skip counting by 2s, 5s, and 10s using number lines.
- Example: To find 4 x 2, count: 2, 4, 6, 8.
-
Grouping
- Explain how to use grouping for multiplication.
- Example: 3 x 4 can be seen as three groups of four items.
-
Using Arrays
- Show how to create arrays to visualize multiplication facts.
- Example: For 2 x 5, draw a grid with 2 rows and 5 columns.
-
Commutative Property
- Explain that changing the order of factors does not change the product.
- Example: 3 x 4 is the same as 4 x 3.
Guided Practice (10 minutes)
-
Have students pair up and practice the strategies demonstrated.
- Provide each pair with manipulatives to model multiplication problems using grouping and arrays.
- Give each student a multiplication flashcard to solve using their preferred strategy.
-
Walk around to offer support and ensure understanding.
Independent Practice (5 minutes)
- Distribute a worksheet with multiplication problems for students to solve independently, using any strategies they learned.
- Problems should include:
- 4 x 3
- 5 x 2
- 6 x 1
- 7 x 2
- 8 x 4
Closure (5 minutes)
- Gather students back together and discuss what strategies they found most helpful.
- Emphasize the importance of understanding multiple ways to tackle multiplication facts.
- Remind students of the commutative property and ask a few quick recap questions.
Homework Assignment
Instructions: Complete the following multiplication problems using any strategy you like. Show your work for each problem.
Problems:
- 3 x 5
- 6 x 2
- 4 x 4
- 9 x 3
- 5 x 5
Homework Answers
- 3 x 5 = 15
- Strategy: [Example: Grouping or Skip Counting]
- 6 x 2 = 12
- Strategy: [Example: Array or Skip Counting]
- 4 x 4 = 16
- Strategy: [Example: Groups of 4 or Array]
- 9 x 3 = 27
- Strategy: [Example: 9 added three times or Array]
- 5 x 5 = 25
- Strategy: [Example: Groups of 5 or Array]
Assessment
- Monitor student participation during guided practice.
- Evaluate independent practice worksheets for understanding and correct application of strategies.
- Review homework for comprehension of multiplication strategies.
This plan provides a structured approach to teaching multiplication strategies to third graders while encouraging independent practice and reinforcement through homework.
