I've designed this lesson to build up students knowledge of calculating with bounds to find the upper and lower bounds.
It begins with a stopwatch starter where students need to to answer 4 questions based around rounding.
A class discussion over how limits of accuracy could affect a consumer buying goods by weight. This leads to a recap on error intervals and a class discussion around why 3.4999... would be written as 3.5 with a less than symbol for the upper bound.
Error Intervals
- 2 examples
- 6 Mini Whiteboard Questions
- Bronze, Silver & Gold Your Turn Section
Multiplying and Adding with Bounds
- 2 Examples
- Bronze, Silver & Gold Your Turn Section
Dividing and Subtracting with Bounds
- 2 Examples
- 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 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.
