Lesson Plan: Understanding the Distributive Property
Subject: Mathematics
Grade Level: 6
Duration: 30 Minutes
Topic: Distributive Property
Objective
By the end of the lesson, students will be able to understand and apply the distributive property to simplify expressions and solve equations.
Materials Needed
- Whiteboard and markers
- Printed worksheets
- Example problems on slides or a projector
- Counters or manipulatives (optional)
Introduction (5 Minutes)
- Begin the lesson by asking students if they have encountered the distributive property before.
- Introduce the concept of the distributive property as a way to multiply a single term across a sum or difference.
- Write the distributive property formula on the board:
[
a(b + c) = ab + ac
]
Explain each part with examples.
Direct Instruction (10 Minutes)
-
Example 1: Simplify (3(4 + 5)) using the distributive property.
- Step 1: Multiply 3 by each term inside the parentheses:
[
3 \times 4 + 3 \times 5
]
- Step 2: Calculate:
[
12 + 15 = 27
]
-
Example 2: Show how to use the distributive property with subtraction:
- Simplify (5(6 - 2))
- Step 1: Multiply:
[
5 \times 6 - 5 \times 2
]
- Step 2: Calculate:
[
30 - 10 = 20
]
-
Engage students by asking them to describe what they notice about the process and the results.
Guided Practice (10 Minutes)
-
Provide students with a few problems to solve as a class:
- (2(3 + 7))
- (4(5 - 1))
- (6(2 + 8))
Encourage students to explain their thought process as they solve each problem.
-
Walk around the classroom to offer help and ensure understanding.
Independent Practice (5 Minutes)
-
Hand out a worksheet with the following problems for students to complete on their own:
- (7(4 + 3))
- (3(8 - 5))
- (9(5 + 2))
-
Allow students to work independently while providing assistance if needed.
Closure (5 Minutes)
- Recap the distributive property and its importance in simplifying expressions.
- Ask students to share what they found challenging or interesting about the lesson.
- Conclude with an encouragement to practice using the distributive property in their homework.
Homework
Problems
Complete the following problems using the distributive property:
- (5(2 + 12))
- (6(3 - 7))
- (4(10 + 3))
- (8(2 - 1))
Answers
- (5(2 + 12) = 5 \times 2 + 5 \times 12 = 10 + 60 = 70)
- (6(3 - 7) = 6 \times 3 - 6 \times 7 = 18 - 42 = -24)
- (4(10 + 3) = 4 \times 10 + 4 \times 3 = 40 + 12 = 52)
- (8(2 - 1) = 8 \times 2 - 8 \times 1 = 16 - 8 = 8)
