Probability 1

9R have now started learning all about probability - the chance of something happening or not happening !!
We worked on the probability number scale and the range from Impossible to Certain. Impossible has a numerical value of 0 and Certain = 1. All probabilities are therefore between 0 and 1.
other words were added, eg. likely, possible, highly unlikely, maybe, random ....

Students made a list of the key words they have used so far in this topic and put them into an image using wordart. https://wordart.com/
We will keep checking they remember the spellings and the meanings !!


Here is an example.

We have begun writing the probability of an event - using our fraction knowledge.
The number on the bottom of a fraction is the total number of possible outcomes of an event and the number on top is how many ways what we want can happen. Students have posted examples on their blog to explain.

All going well so far.
