BIG IDEA Probability

Curriculum Expectations 

Students will: 
*Describe probability as a measure of the likelihood that an event will occur, using mathematical language; impossible, unlikely, less likely, equally likely, more likely, certain 
e.g., “If I take a new shoe out of a box without looking, it’s equally likely that I will pick the left shoe or the right shoe.” 
*Describe the probability that an event will occur (e.g., getting heads when tossing a coin, landing on red when spinning a spinner), through investigation with simple games and probability experiments and using mathematical language.
e.g., “I tossed 2 coins at the same time to see how often I would get 2 heads. I found out that getting a head and a tail was more likely than getting two heads.”

 About The Math 

Students develop concepts about probability by playing games in which they think about the likelihood of certain events (e.g., the likelihood of a spinner landing on a specific colour). Games that involve various spinners and number cubes (dice) help students to understand that factors other than luck can influence the outcome of a game.
