KS2 SATs Reasoning: Reading Line Graphs and Conversion Graphs
Read a line graph by going up from the horizontal axis to the line, then across to the vertical axis. Percy the penguin finds how much the temperature rose between 10 am and 2 pm (8°C), learns to check what each gridline is worth, then uses a litres-to-pints conversion graph in a SATs-style question.

2:03KS2 SATs Reasoning: Missing Angles on Lines and Around a Point
Angles on a straight line add up to 180°, and angles around a point add up to 360°. Leo the lion finds the missing angle next to 125° on a straight line (55°), learns that vertically opposite angles are equal, then you find the missing angle around a point yourself. A regular KS2 SATs reasoning question.
1:54KS2 SATs Reasoning: Area of Triangles and Parallelograms
A triangle is half of a rectangle, so its area is ½ × base × height: a triangle 8 cm across and 5 cm high has an area of 20 cm². A parallelogram is base × height. Ellie the elephant shows why, using the perpendicular height, then you find the area of a triangle with a 10 cm base and 7 cm height yourself.
2:00KS2 SATs Reasoning: Reading Pie Charts
A pie chart shows how a total is shared out. Fizz the fox reads a pie chart of 24 children’s favourite sports: the swimming slice is a quarter of the circle (90°), so a quarter of 24 children chose it, which is 6. Then find how many animals a 120° slice stands for yourself. A frequent KS2 SATs statistics question.
