Rounding to Significant Figures - Full Lesson - Starter, Quizzes, Differentiated & Exam Questions

(All answers are provided)

I've designed this lesson to build up students knowledge of rounding to significant figures.

It starts with 10 quick fire questions on rounding to the nearest 10, 100, 1000 and decimal places.

Then the definition of what significant figures are is given and to be discussed.

This leads into a True or False activity where students need to decide how many significant figures each number has.

Following this are the first 3 examples out of 6. These deal with rounding to significant figures when 0's aren't involved. These are fully animated through clicking to get to the next step.
These then leads to 3 mini whiteboard questions for students to attempt themselves.

Now its time for the next 3 examples. These deal with rounding to significant figures and the 0 rule. I often have a big class discussion around this concept. These examples again lead onto 5 mini whiteboard questions for students to attempt themselves.

Then there is an interactive pairing activity where students need to come to the board and select two cards. If they are a matching question and answer then leave them turned over, if not turn them back over and start again. (Snap)

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 a skill 1, 2 & 3 and a stretch. These are all displayed on the same slide for ease of use.

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.
