I can understand and use correct notation for positive integer exponents.
Lesson details
Key learning points
- There is special notation for squares and cubes and each part can be named.
- Repeated multiplication of the same number can be written using integer exponents.
- Numbers written with positive integer exponents can be expressed as products of the base.
- Products that include repeated multiplication of different base numbers may be simplified using exponents.
Common misconception
When different bases are used student multiply the bases. e.g. 2 x 5^2 = 10^2
Calculate and compare the 2, 2 x 5^2 = 50 & 10^2 = 100
Keywords
