I've designed this lesson to build up students knowledge of error intervals. It includes questions on nearest whole, ten and hundred; nearest five, fifty and five hundred; decimal places and significant figures.
It begins with a stopwatch starter where students need to to answer 4 questions based around rounding.
This leads into a definition about error intervals and why we use the inequality symbols. A nice class discussion is formed around why 3.4999... would be written as 3.5 with a less than symbol for the upper bound.
Nearest whole, ten and hundred
- 3 examples
- 5 Miniature whiteboard multiple choice questions
- 15 your turn questions
Decimal places and significant figures
- 3 examples
- 5 miniature whiteboard questions
- 12 your turn questions
Nearest five, fifty and five hundred;
- 3 Examples
- 5 miniature whiteboard questions
- 15 your turn questions
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 4 separate sections: skills 1, 2 and 3 and stretch 1. 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 2 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.
