Estimating and comparing are two important components of maths and in this activity the pupils look at the angle presented and decide if they are more or less than the angles on the Game Board. At the same time, they can also play collaboratively building up the story of Angle Forest to see if they can save it from destruction. Learning Outcomes: Pupils will know if the angle they see are more or less than obtuse,acute, reflex, right angles or straight line angles.
