In this unit pupils will use knowledge of place value to represent a 3-digit number in different ways. They will compare and order 3-digit numbers and position on number lines and unmarked number lines. In the future unit pupils will compare and order 4-digit numbers. They will learn what rounding is and will round 4-digit numbers to the nearest thousand, hundred and ten.

 In the prior unit pupils explored the counting sequence to 100 and beyond representing the numbers from 20-99 in different ways including on a number line They learned to represent 20-99 as a length In this unit pupils will use knowledge of place value to represent a 3-digit number in different ways They will compare and order 3-digit numbers and position on number lines and unmarked number lines

In this unit pupils will use knowledge of place value to represent a 3-digit number in different ways. They will compare and order 3-digit numbers and position on number lines and unmarked number lines.
