What the teacher knows about Pupil W's attainment in shape, space and measures
Pupil W uses a range of properties of shapes. For example, he recognises parallel sides and perpendicular sides in given quadrilaterals and triangles. He knows that a quadrilateral with just one pair of parallel sides is a trapezium and a quadrilateral with two pairs of parallel sides is a parallelogram. In a group challenge, given the clues, ‘this shape is a quadrilateral, it has just one pair of parallel sides and it also has sides that are perpendicular to each other', Pupil W identified the correct shape from a set of mixed shapes. He reasons about position and movement, for example when deciding which pentominoes1 could be folded to create an open box. He reflects shapes on a grid about a horizontal or vertical mirror line although he is less successful when the mirror line is presented diagonally. He translates shapes horizontally and vertically.
Pupil W identifies acute and obtuse angles and measures them to within 2°. He knows there are 360° in a whole turn. He measures and draws lines to within 2mm. He finds areas of shapes by counting squares and is beginning to use the formula for the area of a rectangle. He works out perimeters by measuring and adding lengths. He uses the terms area and perimeter consistently accurately. He interprets the scale on other measuring instruments, for example reading a value of ‘about 275 grams’ on a scale with increments of 25g and labelled every 100g.
