Most lessons come in double lessons bar the two triple lessons where there is an introductory lesson followed by a double lesson. Each double lesson includes a double lesson PowerPoint that includes an arithmetic starter for every lesson, key vocabulary, modelling, discussion and practice before moving onto an independent activity and challenge tasks that stretch over the two lessons. Answer sheets are included for all independent activities and challenge tasks.
The single lesson at the start of triple lessons has all the same features but only has a single lesson PowerPoint.
