• WELCOME TO MATH!

Today we will begin to look at 'Making Predictions.'
Predictions are used all the time. Someone might predict that because we have covered almost all the material in this chapter of Math, there will be a test coming up...
People predict the weather; people predict which team they think will win the baseball game.

Before we begin the instructions, I'd like you to take a look at the following video, which provides a pretty good understanding of what 'making predictions' is about.

• NEXT, let's think about the following:
Q: In her first 10 times at bat in Little League, Nora got 9 hits.
Do you think that she will get a hit in her next time at bat?
A: Consider that Nora got a hit nearly every time she was at bat. So, based on past performance, we can predict that Nora is likely to get a hit in her next time at bat.

►NOW, let's look at the opening passage on page 248 of your Math textbook.
Please read from the top of the page through the high-temperature scenario.
►Now look at the line plot, and notice where most of the Xs lie.
How does the line plot show that most of the high temperatures were in the 70s?

►A prediction is often based on past results. Predictions may or may not come true. While it seems likely that the next day's temperature will be in the 70s, it may in fact, be higher or lower.
A: Since more Xs are in the 70s, you can predict that the next day's high temperature is likely to be in the 70s.

------------------------

Now, take a look at the scenario with the tiles at the bottom of page 248.
There is a greater likelihood of picking a red tile because there are more red tiles in the bag (5 out of 8 tiles).

Q: Predict what color you are more likely to pick  than any other color if we add 4 more blue tiles to the bag.
A: You are as likely to pick a blue tile as you are to pick a red tile, and even less likely than before to pick a green or orange tile.

------------------------

Please try and figure out the answers to problems 1 through 7 on page 249.
Then, please check your answers against the ones I have written below.

1. 3 out of 8
2. Emily is more likely to win. There are more gold cards than red cards.
3. No; it is more ikely to pick a gold star than red.
4. Red and green; both colors were picked more times.
5. yellow
6. bee
7. ant; more ants were seen by the first class.

NOW, please complete p. 89 in your Math Workbook.
