Make angles facts and missing angles today’s focus. Work out the angles on a clock with the children (each hand goes through 30 degrees when moving from one number to another – when the hands show 3 o’clock and 9 o’clock they represent a 90 degree angle which is a quarter of 360 degrees and the two hands are also perpendicular to each other…). Revise all quadrilaterals (square, rhombus, rectangle, parallelogram, kite and trapezium) and triangles (right-angled, equilateral, scalene, isosceles). Ask: ‘Is it possible to draw a triangle with two right angles?’; ‘ If we drew a right-angled triangle which was also isosceles, what would its three angles be?’
