Significant Figures and Estimation - Edexcel KS3/KS4

Hi,

This lesson is a dummies guide to working with significant figures. I have broken this lesson down into 3 stages; significant figures, estimating and calculating by estimating. There is a good range of differentiation and scaffolding which will cater towards middle to high ability students. I have used a range of AfL to check understanding and cover misconceptions. The last learning objective gives students the chance to work independently and use their prior or current knowledge to work out the questions stated. (The last task on the PPT is optional).

The main activities can be displayed on the board for the students to copy into their books as they show their working out or can be printed. In addition to this, most slides have answers and worked solutions.

I have attached two starters to this lesson so that basic skills can be addressed before the lesson starts. This lesson will take 2/3 hours for a middle/top ability group. Please read the above before purchasing.

The learning objectives covered are:
- I can round to a given number of significant figures.
- I can solve questions by estimating answers correctly.
- I can use one calculation to find the answer to another by estimating.


Enjoy!
