Lesson for partners of 10: Multiplication and Division

Objective: To understand and apply multiplication and division concepts with the number 10.

Materials needed: Paper, pencil, and a calculator (optional)

Lesson:

1. Review the concept of multiplication: Explain to the partners that multiplication is a mathematical operation that combines two numbers to find their total value. For example, 2 multiplied by 3 equals 6 (2 x 3 = 6).

2. Introduce the number 10: Explain that the number 10 is a special number because it is the base of our number system. It is also the number that represents a complete set or a whole.

3. Multiplying by 10: Explain that when you multiply a number by 10, the result is always a number with a zero at the end. For example, 5 multiplied by 10 equals 50 (5 x 10 = 50). This is because multiplying by 10 is the same as adding a zero to the end of the number.

4. Practice multiplying by 10: Give the partners a few examples to practice multiplying by 10. For example, 3 x 10 = ?, 7 x 10 = ?, etc. Encourage them to use mental math or a calculator to find the answers.

5. Division with 10: Explain that division is the opposite of multiplication. It is the process of splitting a number into equal parts. When dividing by 10, the result is always a number with a decimal point moved one place to the left. For example, 50 divided by 10 equals 5 (50 ÷ 10 = 5).

6. Practice dividing by 10: Give the partners a few examples to practice dividing by 10. For example, 80 ÷ 10 = ?, 60 ÷ 10 = ?, etc. Encourage them to use mental math or a calculator to find the answers.

7. Real-life examples: Discuss real-life situations where multiplication and division by 10 are commonly used. For example, converting kilometers to meters (1 kilometer = 1000 meters) or converting dollars to cents (1 dollar = 100 cents).

8. Application: Provide partners with word problems or numerical problems that involve multiplication and division by 10. For example, “If a box contains 10 packs of pencils, and each pack has 10 pencils, how many pencils are there in total?” (10 x 10 = ?)

9. Review and assessment: Review the concepts of multiplication and division by 10 with partners. Ask them to solve a few problems independently to assess their understanding.

10. Extension activity: Challenge partners to create their own word problems or numerical problems involving multiplication and division by 10. They can exchange problems with each other and solve them.

Note: Adjust the difficulty level of the problems based on the partners’ abilities and provide support as needed.
