Unit B – Ordering and Changing

This maths scheme of work for Key Stage Two gets the children to explore how to order three digit numbers by the place value of their digits and how the digits change their values when finding ten and one hundred more or less. The class can use concrete equipment and diagrams to model how to order and change numbers.

Explore and record how to order three digit numbers by the place value of their digits and how the digits in a number change their numerical values when finding ten and one hundred more or less

Lesson One : Number Steps

Identify, estimate and record the position of different three digit numbers using a number line to indicate their matching and comparative values

Lesson Two : Number Places

Estimate and record the position of different three digit numbers on a range of number lines to indicate their matching and comparative values based on their numerical digits

Lesson Three : Changing Numbers

Identify and record number sums that are ten more than different three digit numbers using abacus diagrams to model their changing values

Lesson Four : Digit Changes

Identify and record the matching number sums that are ten less than different three digit numbers by illustrating changes to the values of their hundreds, tens and ones digits

Lesson Five : Changing Hundreds

Explore and record the matching number sums that are one hundred more and less than different three digit numbers to show changes to the place values of their numerical digits
