A maths game is also in the pack where students can sort the data from the cards to form two way tables.Engage and excite your learners about two way tables rather than just transfer information ... We have a total of 20 snowy days and we are delayed 12 of those 20 snowy days, and so this is going to be a probability, 12/20 is the same thing as, if we multiply both the numerator and the denominator by five, this is a 60% probability, or I could say a 0.6 probability of being delayed when it is snowy.
