This is an Excel file with a basic odd/even activity. I took inspiration from Jean Thomas’ “Reveal the hidden shapes!” activity from 2005.
With this activity, the tutor can design a picture (or one learner can design a picture for another learner) and it produces a printable sheet. The learner then shades all the odd numbers on the sheet in one colour, and all the even numbers in a different colour – revealing a picture or a message.
There are no macros, so cross-compatibility with Excel shouldn’t be a problem.
