This is a scheme of work to introduce the concept of factors through the investigation of the shape of numbers, and to encourage the use of a systematic approach to problem solving. The bundle contains five activity sheets and. sixty short factor-finding investigations in three packs of twenty, each at different levels of difficulty.

These are PowerPoint whole class/group activities to develop and reinforce mental dexterity and understanding of place value and larger numbers. They follow on from the foundation level packs, and provide practice in digit value identification, division by powers of 10 and rounding to multiples of 10, 100, 1,000 etc. up to 1000,000,000 Included in the bundle are 10 presentations, each providing 52 questions to ask around the class or group.

These are PowerPoint whole class/group activities to develop and reinforce mental dexterity and understanding of place value and larger numbers. The first is to check basic grasp of HTU. The second deliberately bypasses consideration of ‘thousands’ as the next column after units, tens and hundreds, and moves instead to the more logical step: HTU of thousands. Included in the bundle are a further 12 presentations, each providing 30 questions to ask around the class or group.
