Puzzle Box Challenges

Our new Puzzle Box Challenges are a great way to revise Key Skills at the end of the year or to use during the year to revisit concepts that have been learnt previously.  Answer the maths problems to discover the codes, then unlock the padlocks to open the box and collect your reward!

Our FREE online Puzzle box can be set with the correct codes then displayed on a laptop, tablet or big screen for individual children, groups or even whole classes to see how quickly they can open the box.
