This game was a natural development from my KABOOM Doubling Game as the students progressed.
It has the same format and rules as KABOOM Doubling and I will put it up as a bundle for those of you who can see the need.
It is great for motivation because the KABOOM factor means that the players get to know the halves they need to avoid a KABOOM. That's the beauty of becoming fluent in mental maths - they learn through fun.
The pictures are a great support for those mastering the halving facts, but the game is great consolidation as well. You can add it to a Maths Centre to cater for a range of learners.
I have heaps of games like this in my store.
