Using Place Value

In this Year 3 'Using Place Value' scheme of work your class will begin to apply their knowledge of three-digit numbers to addition and subtraction problems. They will be encouraged to use a variety of resources, including blocks and place value cards, to reinforce their knowledge of the value of the different digits in a number.

With detailed lesson plans, engaging slides, differentiated worksheets and other resources, these 'Using Place Value' lessons provide all you need to teach this useful scheme of work.

What's the Value?

The first lesson in this series recaps what each digit is worth in a three-digit number, as well as encouraging your class to be able to read and write numbers up to three-digits in numerals and words. They will practically add multiples of ten to a given number to reinforce their understanding of place value addition.

Solving addition problems

The slides in the lesson use both dienes blocks and place value cards to demonstrate how this apparatus can help children solve addition problem using their place value knowledge. Children will learn how to use partitioning to help them add one-, two- and three-digit numbers to an existing three-digit number.

Solving addition and subtraction problems

Your class will begin to move away from solving problems practically with objects as they work towards solving problems in the abstract using partitioning. They will add two-digit and three-digit numbers to a given three-digit number.

Solving problems using number lines

In this lesson, your class will partition numbers in order to add or subtract them using a number line. They will work out what the given word problems are asking them to do and then write the question as a number sentence before solving it. There is also the chance to create some word problems of their own for a friend to solve!

Three-part word problems

For the final lesson in this series, your class will consolidate their knowledge of place value by solving three-part word problems using number lines. The problems will involve addition and subtraction and bridging ten. Higher-ability children are challenged to bridge a hundred.
