There is several scenarios of booking a hotel room in 'Pythagoras Palace&'. The questions are split into groups with different levels of ability so the activity can easily be differentiated. Students have to consider how many nights they are staying, the type of room, special offers, cost occurred for breakfast/dinner and so on.
Ideal for KS3 and KS4 students.

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.

A useful help sheet that I usually laminate to measure the area and perimeter of shapes in KS2.
Children friendly and easy to read.
Objective: Measure and calculate the perimeter of a rectilinear figure (including squares) in centimetres and metres.
I can calculate the area of rectangles in square centimetres (cm2) and square metres (m2) and estimate the area of irregular shapes.
