Activities in this teaching pack include differentiated templates to select and record a range of numbers that are ten more than different three digit numbers for core and extension ability levels and two digit numbers for support ability levels using abacus to model their changing place values.

The interactive presentation gets the children to explore how to record number sums that are ten more than different three digit numbers to indicate changes to the place values of their numerical digits.

This lesson is part of a maths scheme of work to get the children to 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. There are teaching activities for shared learning, differentiated worksheets to support independent learning and interactive presentations to introduce concepts and key skills.
