Lesson Details

Key learning points

Partition the mixed number into a whole number and a fraction.
Multiply the whole number part by the whole number factor.
Multiply the fraction by the whole number using unitising language.
Recombine the partial products to calculate the overall product.

Common misconception

Pupils find it difficult to represent the problem as an expression or equation as they misinterpret what the whole is.

Draw attention to what the whole is in each example. You might like to build up each image with a whole at a time, describing the fraction of the whole that is shaded/represented.
