Completing symmetric figures for Year 4, over four pages. Pupils use a ruler to draw the missing half of eight shapes across a dashed mirror line on a squared grid. The shapes are an arrow, a house, an E-shape, steps, a podium and a boat hull, with vertical and horizontal mirror lines. The last two are challenges with a diagonal mirror line. Page 4 shows every finished figure. It follows England National Curriculum properties of shapes.
Geometry - properties of shapes
“complete a simple symmetric figure with respect to a specific line of symmetry”
All eight questions give half a figure and a mirror line, from a vertical line for the arrow to a diagonal line in questions 7 and 8.
An arrow and a house, each half drawn on a squared grid beside a dashed vertical mirror line. Pupils count squares to draw the other half.
An E-shape above a horizontal mirror line and a set of steps beside a vertical one.
A podium and a boat hull above horizontal lines, then two challenge grids where the diagonal mirror line runs through grid corners. Pupils reflect each corner across the diagonal.
All eight completed figures in small grids, with each mirror line marked.
Count the squares
Remind pupils to count squares from each corner to the mirror line and the same number on the other side. Pupils who guess by eye often get the steps wrong.
Diagonal challenge
Keep questions 7 and 8 for pupils who finish the first six quickly. Tracing paper turned over along the diagonal checks the answer.
Mirror check
Pupils hold a small mirror on the dashed line to see whether the figure looks whole.
