Ordering and Comparing Decimals — Interactive Lesson (Ages 9–11)

Do decimal comparisons still trip pupils up once the numbers have different amounts of digits after the point? This 23-slide interactive lesson gives pupils focused, self-marking practice ordering and comparing decimals using place value.

Mastering Ordering and Comparing Decimals in Year 5–6 Maths

Pupils practise comparing and ordering decimal numbers by reasoning about place value rather than digit count, building the fluency within the Year 5 and Year 6 National Curriculum area of number and place value. This is a common area of misconception, and the structured, self-marking format lets pupils correct their own thinking as they go.
