Patterning: Winter's Coming, Yeah Snow Days!

Whether you like it or not Winter is coming. Every year It comes, without fail, which is of course a predictable pattern itself. One of the most exciting events that sometimes occurs with winter snowfalls is the Snow Day. Sometimes Snow Days are called the night before. How does our Director, Mr. Milloy know when to call a Snow Day? You guessed it...patterning! If he knows how much snow will accumulate hour to hour, then he will be able to predict when it will reach an unsafe level.

Try predicting the amount of snow that will fall yourself. What strategies could you use to figure out the pattern? How could you graph the amount of snow that will fall?

If the snow is 11 cm deep at 3 p.m. and 6 cm of snow falls each hour. How deep is the snow at 7 p.m.?
