Four rods are hinged at their ends to form a convex quadrilateral with edges of length 3, 4, 5 and 6 (in that order). Investigate the different shapes that the quadrilateral can take if the polygon is always convex.
How do the angles change […]
The graph and table show the Gross Domestic Products (GDP) of the world’s top ten economies in 2016 and the forecast for 2030.
Draw a double bar chart to compare the GDPs for these eleven countries in 2016 and 2030 (forecast).
Which countries are in the top […]
This is the first in the ALL ABOUT SCALE sequence of lesson packs.
Watch the video http://bit.ly/ScalePaperAirplanes. The video gives instructions for making the planes but you can use your own design. Using scrap paper is more planet friendly.
Make enlargements of the coloured shapes by fitting together four identical smaller shapes.
How much longer are the edges (the linear scale factor of the enlargement)?
How much bigger is the area (the area scale factor of the enlargement)?
Now look at the illustration of the 3-dimensional solids. One is […]

The table gives data on the land and sea covering the Earth’s surface.
(1) Explain how the percentage 69.03% of saltwater that makes up the Earth’s surface is calculated from these figures.
(2) How would you use this percentage to find the angle for saltwater for drawing a pie chart?
A pie […]
