## Three-digit numbers

• Year group: Year 3
• Term: Autumn
• Topic: Number and place value
• Duration: 3 weeks
• Keystage: KS2
• Age Range: 7 to 8 yrs
• Unit can be taught out of sequence: N
• Week Range: 1 - 3

In this chapter, pupils identify, represent and estimate numbers to at least 1,000 (ie, hundreds, tens and ones) using a variety of representations, including those related to measure.

They compare and order numbers up to 1,000 and they apply partitioning related to place value (eg, 146 = 100 + 40 + 6, 146 = 130 + 16). As ever, it is important that concrete and pictorial representations are used throughout.

Many children have been learning to say which number is “one more” or “one less” than a given number since before starting school; first with numbers within 5, then within 10, then within 100 and now within 1,000. This is extended further in this chapter by asking pupils to find 10 and 100 more or less than a given number. This helps pupils deepen their understanding of place value, particularly when working with numbers that move into the next 10 or 100.

## Resources for this topic

### White Rose Maths

#### Inequality symbols

This worksheet supports learning with concrete materials such as Ten Frames, Place Value counters and Base 10 using the symbols >, < and =

#### Compare and order numbers up to 1000

This resource is great if you have been using counters as a concrete model before moving onto pictorial and abstract.

#### Place value problems

A resource to extend and deepen children's understanding of place value.

#### Place value - Up to 4 digits

A selection of place value resources that link directly to concrete materials such as straws, Base Ten and counters. The resources include fluency, reasoning and problem solving questions.

### Mathematics Mastery

#### Three-digit numbers

Mathematical discussion is a key element of the Mathematics Mastery programme.

Talk Tasks are a brilliant way of enabling pupils to develop their mathematical language, thinking, understanding and confidence.

This activity explores the concept of three-digit numbers.

• Talk tasks are best completed in mixed attainment pairs, with pupils taking turns to listen and construct arguments
• Emphasis is on discussion rather than the solution, encouraging pupils to use key language and talk in full sentences
• Ask pupils to prove their answers in a variety of ways, using the CPA approach to support mathematical understanding and number sense

Like what you see? Mathematics Mastery is a professional development programme for teachers with a mission to transform mathematics education in the UK.

This task is just a taster of the complete classroom resources we offer. We also provide in-depth development training, online CPD, specialist support and assessment tools.

We believe all elements of our programme are vital in creating lasting change – enabling every child to enjoy and succeed in mathematics.

#### Three-digit numbers

Deepening pupils’ understanding of key mathematical ideas is a core element of the Mathematics Mastery programme.

Our Key Constructs highlight the essential mathematical concepts all pupils are expected to grasp within each year group, with accompanying guidance for assessing pupil progress.

Our Key Constructs are closely aligned to the National Curriculum’s objectives. We know these can be tricky to evidence, so we’ve included an example task for each concept, as well as ideas to support slower-graspers and depth tasks to challenge higher-attaining pupils.

• Pupils should work through the tasks independently
• Teachers should incorporate the CPA approach to support pupils’ learning
• Opportunities for depth and scaffolding are built into each task
