A simple starter worksheet looking at recognising squares. A square is a regular type of rectangle as it has four right angles and all four sides are equal in length. For those of you who like to think about these things, it is a special case of a rhombus, kite, parallelogram and trapezoid. However, for the average five year old recognition alone is enough. Concentrate on pointing out that the sides have to be equal in length.
Most children will recognise a square when it is positioned horizontally on the page, put if it is tilted at an angle and appears to look more like a four sided star then this is much tougher to spot.
