KS2 Mathematics - Addition and Subtraction - Calculation of Perimeter

Lesson for Key Stage 2 pupils - year 5 and 6 (can be adapted to others). Follows a focus of applying previous lessons of addition and subtraction skills to then be applied for the calculation of perimeter. Fully differentiated lessons for lower, middle and higher ability. Use of connection, activation, activity and demonstration. ~Allows for regular use of assessment to feed in to lesson delivery. Applying decimal numbers and allowing for numbers with different numbers of digits and decimals. Higher ability can work towards deducing missing measurements.

Aspire: I can recognise the measurements required to solve missing values from shapes based on their perimeter.
Challenge: I can accurately calculate the perimeter of compound shapes.
Achieve: I can recognise and calculate the perimeter of common shapes.
