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)

Sofia is chanting her 4 times tables. 4, 8, 12, {{ }} What comes next?

Look at the image. Which word is the correct label?

Look at the image and the missing label. In a multiplication equation this number is known as the {{  }}  .

Using short multiplication calculate: 23 × 3

Using short multiplication calculate: 43 × 2

What is the missing factor in this expanded multiplication example?

Look at the multiplication equation. You can partition 17 into 10 and {{  }}.

Look at the image. Complete the equation.

Select the correct partial product pair that completes the model in the image.

Select the correct partial product sums for this multiplication equation: 35 × 3

Match the multiplication equation with the correct partial product pair.

Which multiplication equations consist of zero regroups?
