About IOIO

This is a really nice app that provides a good level of practice in comparing numbers. It is permanently free without any advertising or in-app purchases. It provides a good explanation of the greater than, less than, and equals signs. It does a less effective job of explaining the activity, which is a shame because it is good.

Fortunately, this explanation should help you out. The goal of the activity is to find the combination on the scroll. The scroll is made up of sections that have numbers and signs on them. Players have to rotate these sections to be mathematically correct and then test to see if it is the searched-for combination. If it is, they have won the level, if not they try another combination. Working methodically is a good idea.

Children will get plenty of practice in this app and its game-like graphics make it fun too. As a bonus, children can also compare numbers from other systems such as Roman numerals which they will be expected to learn as part of the Key Stage 2 curriculum.
