A sorting task on flat and solid shapes for Year 1 maths. Pupils place items like a flat circle, a football and a paper square into 2-D and 3-D columns using a word bank, then answer two reflection questions, including which item was trickiest to place. The answer key explains both. It covers the England National Curriculum objective on naming common 2-D and 3-D shapes.
Geometry — properties of shapes
“Recognise and name common 2-D and 3-D shapes, including: 2-D shapes [for example, rectangles (including squares), circles and triangles] 3-D shapes [for example, cuboids (including cubes), pyramids and spheres].”
Sorting real items forces the flat-versus-solid distinction.
Items sorted into 2-D and 3-D columns from a word bank.
Pupils name the trickiest item and add one new flat and one new solid object.
Explanations for both reflection questions.
Misconception fix
Use when pupils call a football a circle; the columns make the difference visible.
Paired work
Sort together, then write the reflections independently.
Assessment check
The add-your-own question shows who can generate examples, not just sort given ones.
