Numbots

To help our children in Year 1 and Year 2 become fluent with addition and subtraction facts we have introduced the online resource Numbots.

The information below explains how the website works.

Mode 1: Story Mode for Understanding

Story Mode features visual representations, procedural variation, different calculation strategies and material in a very carefully sequenced order.

Children will be able to unlock levels (Rust, Tin, Iron, etc) a bit like Angry Birds.

Rust is the first level which is where everyone will start.

To unlock the next level, children need to earn two stars.

The aim is for children to play in Story Mode for at least three minutes four to five times per week, every week.  By playing little and often the children will become both more fluent and accurate.

Mode 2: Challenge Mode for Recall

In Challenge Mode, the emphasis is on rapid responses to essential facts and simple sums, against the clock.

Challenge Mode is locked for new users and is unlocked once the children reach a certain level on Story Mode. There are 20 Challenge levels and only the first is unlocked to begin with. To unlock the next Challenge, children must correctly answer 12 questions in a minute.
