Lesson Five – Subtracting Tens
This maths teaching pack for Key Stage Two gets the children to practise subtracting different multiples of ten from a range of three digit numbers using an abacus to model each of the subtraction number calculations.
The class can explain and model how to use exchange between place value when completing each step in the subtraction calculations to illustrate how the digits can change.
Download this teaching pack including a lesson plan, classroom activities and an interactive presentation to practise subtracting different multiples of ten from a range of three digit numbers using an abacus to model each of the subtraction number calculations
Activities in this teaching pack include a differentiated set of worksheets to record how to subtract different three digit numbers and tens using an abacus to show changes to the place value of the digits in the numbers when completing each subtraction number calculation.
The interactive presentation gets the children to explore how to subtract multiples of ten from different three digit numbers using an abacus to model the calculations.
This lesson is part of a maths scheme of work to get the children to develop and refine mental and informal written calculation skills when subtracting different pairs of three digit numbers and ones, tens and hundreds. There are teaching activities for shared learning, differentiated worksheets to support independent learning and interactive presentations to introduce concepts and key skills.
