• Method of estimation of finding the cube root of a number.

LEARNING ACTIVITIES:

PROCEDURE

Introduction: Start the lesson by asking students if they have heard the terms "cube" and "cube root" before. Then, define what cube and cube root are:

Cube: The cube of a number is the number raised to the power of three. 

For example, the cube of 2 is  2 x 2 x 2 = 8.

Cube Root: The cube root of a number is the number that when cubed, gives the original number. 

For example, the cube root of 8 is 2 because 2 x 2 x 2 = 8.

Teaching:

Demonstrate how to find the cube of a given number. Use some examples such as:

3³ = 27

5³ = 125

(-2)³ = -8

Explain how to find the cube root of a given number. Use some examples such as:

Cube root of 27 = 3

Cube root of 125 = 5

Cube root of -8 = -2

Provide some practice problems for the students to solve in pairs or individually. Example problems may include:

a) Find the cube of 7 

b) Find the cube root of 64 

c) Find the cube of -4 

d) Find the cube root of -125

Once students have completed the practice problems, go over the answers as a class.

Assessment: 

Have the students complete a worksheet with additional practice problems on cube and cube root. Collect the worksheets and review them to identify any areas where students may need additional instruction.

Conclusion: 

Summarize the key concepts covered in the lesson and remind students of the importance of understanding cube and cube root in mathematics. Encourage them to practice these skills further to strengthen their understanding of the topic.
