Goat to bed (Partitioning twenty) - ABC Education
TLF ID A005644
Some naughty little goats should be in bed, but they are still up and playing games! You will need to choose teams, then use your strategies (such as combinations for 20) to decide who wins: baby goats or babysitter! Mathematical ideas and strategies this game supports: numbers can be partitioned in many ways; there are many ways to add and subtract numbers to make a total; independent events have the same likelihood/probability of occurring; number lines can show how numbers can be partitioned.
