A way of recording the steps of a calculation focusing on partitioning one or more factors and showing partial products.

Any of the multiplication results that lead up to an overall multiplication result.

Multiply a 2-digit number by a 1-digit number using expanded multiplication (no regroups)

Maths

In this unit pupils will multiply a 2-digit number by a single-digit number using partitioning and representations using expanded multiplication and using short multiplication. In the future unit pupils will multiply a 3-digit number by a single-digit number using expanded and short multiplication.

In the prior unit pupils explained the relationship between multiplying and dividing a number by 10 and multiples of 10. In this unit pupils will multiply a 2-digit number by a single-digit number using partitioning and representations using expanded multiplication and using short multiplication.

Multiplication by partitioning leading to short multiplication (2 by 1-digit)
