Negative numbers - starter

Many children initially look at the calculation 1 - 5 = ? and say 4. The need to see what is happening on a number line is paramount. ‘Negative numbers’ is a ten-page app introducing pupils (age 9-13) to the need to extend their knowledge of number beyond the positive counting numbers. ‘Negative numbers - starter’ is a three-page, no charge mini-app providing a flavour of the full app. The three pages we have chosen to give away here are pages 1, 4 and 5 of the complete app. The full set of ten pages can be purchased in the usual way - tap an inactive screen and follow the instructions to the shop. Better, download the main LDM (‘Let’s do maths’) app and you will automatically have these three pages and all other free pages available under the LDM title.

Age range: 9-13
