A short read for Class 8 before you play. These notes cover Power Play: paper folding, laws of exponents, counting codes and scientific notation.
📄 Folding makes powers
A sheet of paper doubles in thickness with every fold. Starting at 0.001 cm, ten folds make it about 1024 times as thick. Writing 2 × 2 × 2 × 2 as 2 to the power 4 turns long products into short exponential form.
⚖ Laws of exponents
For the same base, multiplying adds the exponents, dividing subtracts them and a power of a power multiplies them. This also shows why any non-zero number to the power 0 is 1 and why a negative exponent gives a reciprocal.
🔭 Codes and huge numbers
Counting choices by multiplication shows that a 3-digit lock has 10 × 10 × 10 = 1000 codes. Scientific notation writes huge numbers such as the Sun to Earth distance as a number from 1 to 10 times a power of 10.

Power Play Class 8 FAQs
What is an exponent?
An exponent tells how many times the base is multiplied by itself, so 2 cubed is 2 × 2 × 2 = 8.
Why is any number to the power 0 equal to 1?
Because n to the power a divided by n to the power a is 1, and by the law it is n to the power 0.
How do I write a big number in scientific form?
Write it as a number from 1 to 10 times a power of 10, counting how many places the decimal moves.
How do I count combinations?
Multiply the number of choices at each step, like 10 × 10 × 10 for a 3-digit lock.
What can students do on this page?
Students can take a 20-question online quiz with assertion and reason and case study questions, play five games, try five online activities, finish five challenges, run the Power Lab, do two virtual experiments, fold a 1 mm sheet five times and compare the bars and table views,, and fill in a 16-question practice sheet with a Show answers button.
