This is a worksheet which asks the student to find the circumference of ten circles using the formula pi x d.
Each question gets the student to show how they got their answer step by step and has prompts to help them.
Each question differentiates to make the pupils think about what numbers they have to use.
Also has pi to 422 decimal places around the border which could be used as a game in class - who can remember pi to as many decimal places as possible.
Please leave a comment and let me know how it went. Enjoy!
To be used after both area and Circumference has been taught as a consolidation lesson or as a revision lesson towards exam time.
This worksheet also includes compound shapes made with circles.
Many thanks to Lois Lewington for correcting a few repeats and providing the solutions to the questions for us.
An easy to use, free online adaptive quiz from Mangahigh.
Find the circumference of a circle or simple arc lengths and perimeters, e.g. perimeter of a semi-circle. Include simple compound shapes, e.g. a rectangle and two semi-circles. Include approximations (pi=3), use pi button and answers in terms of pi.

GCSE Solving simultaneous equations using a graphical method. This worksheet only has straight line graphs. No curves. I haven’t put numbers on the axes (way too fiddly in word when I’m on a time limit) but they are intended to go up in ones. As always, if you use it - please review it. Eek! Q6 has a slight mistake. It should be -x+y
Need to spice up this rather dry topic.
For this dot to dot have students join question number to answer, e.g. Q1 find 10% of 80 so join 1 to 8. You must say to them to then do Q8 rather than 2 for two reasons:
1. it's quicker as you know where dot 8 is and don&'t need to waste time searching for dot 2.
2. The questions gradually get harder around the shape.
Adventure game in which students answer KS3 circle questions in order to rescue a princess. Teacher notes and answers are provided. There are 5 sections, each with 2 topics. They have 4 attempts at each topic, if they get all 4 wrong, the game ends and they will have to start again. The 5 sections are: parts of a circle, circumference, area, reverse questions: given circumference, find diameter and radius; given area, find radius and diameter. Go to my profile page to see the GCSE version including arc length and sector area and check out my other games.
Investigation and problem solving activity in which students identify all the different pentominoes, then fit them into shapes (50 different shapes, inc. 4 rectangles, 4 squares, 17 animals, 13 pictures (inc. car, train, plane, rocket, boat), 12 other shapes (inc. cross, yin and yang, heart)).
