Class 08 Activity – Exponents and powers

 Activity – Exponents and powers

Objective: 

To find the values of 20, 21, 22 by paper folding activity.

Materials Required:  

Few rectangular paper cutouts, scale, pencil

Preparation for the Activity:

The rectangular pieces of paper represent the base 2.

2. Number of times the rectangular pieces will be folded that will represent the power

Demonstration and Observation:

Take a rectangular piece. This is not folded. So, it is folded zero time.

2. Now take another piece of paper. Fold it into two equal parts along the length. Here, the fold has been made one time. Open the paper. We find two equal parts.

3. Take another piece of paper and first fold it into two equal parts along the length as done in step 2. 

Then, similarly fold it once more along the width. 

We have folded the paper two times. Open the paper. 

We find 4 equal parts of rectangles. Make lines along with it.

Two be Draw the line segment among the creases to get 4 such rectangles.

4. Take another piece of paper and first fold it as done in step 3. 

Then once again fold it along the breadth. We folded the paper three times. 

Open the paper and count the number of equal rectangles.

 Draw the lines along with the creases to get 8 equal rectangles.

 Keep on folding to get further results.
