Let's Add Big Numbers - The Complete Series (5 lessons)

With detailed lesson plans, informative slides, activity ideas and differentiated worksheets, this 'Let's Add Big Numbers' scheme of work has everything you need for five Maths lessons.

In this first lesson, children discuss and understand the value of each digit in two- and three-digit numbers. They use this knowledge to partition each number into tens and ones, or hundreds, tens and ones. Children then apply this understanding in their independent activities.

In this lesson, children use their partitioning skills to add a two-digit number to a multiple of ten. They explore and practise the steps needed to solve different addition number sentences, and then apply them in their independent activities.

Children progress to using their partitioning skills to add two two-digit numbers together, by first partitioning each number and then recombining them as tens and ones, before adding these two numbers together to find the final answer. The independent activities give children further opportunities to practise this method of addition.

Children apply their knowledge and understanding of partitioning to help them solve addition word problems involving money. They learn how to bridge through ten in order to add together a wider range of numbers. In their independent activities, children find the total amounts spent during a trip to several shops. In the FSD? activity, children work as a group and use trial and improvement to decide what two items can be bought for a given price.

In this final lesson, children focus on adding two two-digit numbers mentally. They first work in pairs to partition and then recombine the separate tens and ones totals, and are then challenged to solve number sentences mentally by themselves. In their independent activities, children generate their own number sentences for others to answer.
