Common Misconceptions  Place Value That estimations are good guesses and are unlikely to be the exact answer.as this would suggest that there would be no need to estimate. That only the digits 0 – 9 are used to make all other numbers and the value of the number is dependent upon the places that they hold in a number. When making complements to 100 – children will often give responses that make a total of 110 and they need to understand that the ones need to add to 10 and the 10s need to add to 90 – ie the complement to 100 of 67 is 33 Common Misconception  Properties of Shape What do we mean by a 2D shape and a 3D shape – 2D just have length and width and 3D have length, width and breadth That 2D shapes are only found as a face of a 3D shape. (You are not able to hold a 2D shape.) That 2D shapes that have all sides the same size, all angles the same size are regular and others are irregular. That it doesn’t matter in what orientation a shape is, it is still that shape according to properties, ie a square or ‘upside down’ triangle etc.
