This is one of the best games for early years / SEN maths. I have been using it for over 10 years. The children love the creatures and the fact that 'Miss' often loses! It teaches / reinforces many things: odds / evens; count on / count back; + / -; which number comes first in a minus sum; prediction ~ will 'Miss' get to the short cut before they do; estimating how many you need to finish - exact number or not? how to lose, when 'Miss' eventually wins a game; taking turns; all good fun. Well worth the money.
