First, a tutor prepares materials for children. One should draw a semi-circular shape of a snow house built with bricks using a blue felt-tip pen on a white sheet of paper. Then we cut it – an easy puzzle is created. On a sheet of coloured paper – which serves as a background, we draw with a pencil the same shape (also bricks). A child is now to match pieces of a puzzle to a shape drawn on the paper. He/she glues particular parts in respectable places – building his/her own ice house.
