probability....
Impossible, unlikely, even chance, likely, certain.
We talked through a number of scenarios and discussed them in terms of this vocabulary.
We found that some things that were likely for some people were unlikely for others.
We talked about putting a numerical value to probability.
Examples we used initially were a coin toss, dice, playing cards.
We continued to divine a method based on fractions to express the probability. eg if there are 2 possible outclmes and one actual outcome the probability is 1 in 2 or 1/2 - also expressed as 0.5 or 50%
We applied this method to dice and playing cards
We looked at a variety of different scenarion snd as a class discussed number of word problems including questions on probability
