I've designed this lesson to build up students knowledge of evaluating indices. The resource includes activities on Power of 0, Reciprocals (Power of -1), negative powers, square & cube roots as fractional powers, harder fractional powers such as 2/3 and 3/2 and negative fractional powers.
It begins with a stopwatch starter where students need to to answer 4 questions based around square and cube numbers and roots.
This then leads to a series of examples, mini whiteboard and differentiated questions.
Evaluating power of 0
- 2 examples
- 2 Mini Whiteboard Questions
Evaluating negative powers
- 2 examples
- 5 Mini Whiteboard Questions
- Bronze, Silver & Gold Your Turn Section.
- Use of calculator for negative powers.
The resource then includes a discussion slide on the pattern of indices. work through powers of 3, 2, 1, 0, -1, -2. This will then be a nice link into harder indices lessons.
Evaluating power of a half and third fractional powers.
- Explore task relating power of 2 and power of a half.
- 2 examples
- 4 Mini Whiteboard Questions
- Use of calculator for roots and fractional powers.
- Bronze, Silver & Gold Your Turn Section.
Hard Fractional Powers
- 2 examples
- 2 Whiteboard Questions
- Bronze, Silver & Gold Your Turn Section.
The resource then in includes a differentiated focused activity which progressively gets harder. This gives students a chance to master and enhance their skills. It includes 5 separate sections: skills 1, 2 & 3 and a stretch 1 & 2. These are all displayed on the same slide for ease of use, however could be printed as a worksheet.
Then to finish there is an application on how this could be seen in an exam situation with several exam style questions including answers.
I hope you find this resource as useful as my students have. Any of the the slides could be printed as worksheets if you feel that would be easier for your class.
