Description

In this unit pupils will find pairs of number that compose 100. They will position 3-digit numbers on a number line and estimate their position on unmarked number lines. They will compare and order 3-digit numbers.

This unit develops the knowledge of multiples of 10 totaling 100 to pairs of numbers that compose 100. Pupils use place value knowledge to represent 3-digit numbers in different ways, including on a number line. They calculate mentally with 3-digit numbers, finding 10 more and less, adding and subtracting 2-digit multiples of ten in preparation for more formal calculations in later units.

  1. Count across and on from 100
  2. Represent a 3-digit number up to 199 in different ways
  3. Bridge 100 by adding or subtracting a single-digit number
  4. Find 10 more or 10 less than a given number
  5. Cross the hundreds boundary when adding and subtracting any 2-digit multiple of 10

  • Recall number facts and sequences
  • Use place value understanding
  • Apply basic operations in context
