Grade 5 Math Lesson Plan: Divide Decimals

Objectives:
- Students will be able to divide decimals by whole numbers and decimals.
- Students will understand the concept of dividing decimals and how it relates to real-life situations.
- Students will be able to solve word problems involving division of decimals.

Direct Instruction:
1. Explain the concept of dividing decimals to the class.
2. Discuss the steps involved in dividing decimals, including moving the decimal point and adding zeros if necessary.
3. Key concepts to cover include:
- When dividing decimals by whole numbers, move the decimal point in the dividend to the left the same number of places as there are zeros in the divisor.
- When dividing decimals by decimals, move the decimal point in the divisor to the right until it becomes a whole number, and move the decimal point in the dividend the same number of places to the right.
4. Provide examples of dividing decimals, both by whole numbers and decimals.
5. Model how to solve word problems involving division of decimals.

Guided Practice:
Divide 4.8 by 2
Solution: 4.8 ÷ 2 = 2.4

Closure:
Ask students to share one real-life situation where they might need to divide decimals. Review the steps involved in dividing decimals and remind students to practice this skill at home.

Independent Practice:
Provide students with a set of division of decimals problems to solve independently. Examples could include:
- 6.5 ÷ 0.5
- 3.6 ÷ 0.2
- 0.8 ÷ 0.4
- 9.3 ÷ 3
- 2.5 ÷ 0.5

Assessment:
Observe students during guided and independent practice to ensure they are applying the steps correctly. Check independent practice for accuracy and understanding.
