Comparing and ordering numbers with 1, 2 and 3 digits

Ordering sets of 3-digit numbers

Use known facts to add and subtract multiples of 100 within 1000

Write a 3-digit multiple of 10 as a multiplication equation

Use known facts to solve problems involving partitioning numbers

Use known facts to add and subtract to and from multiples of 100

Add and subtract to and from a 3-digit number bridging 100

Count forwards and backwards in multiples of 2, 20, 5, 50 and 25

Solve problems by counting forwards and backwards in multiples of 2, 20, 5, 50 and 25

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.

Complete the calculation. 200 + ___ = 270

Which two numbers can 230 be partitioned into? 

Calculate the missing part. 200 + {{ }} + 40 = 340

What is the value of the missing part in the bar model?

Match the equations to their correct sums.
