Negative Exponents? Ugh

…udents skip ahead several inputs and are forced to consider a rule to model the situation. Next we ask students to think about how they might work backwards. If you know the height of a plant during its 9th month, how can you find it’s height at the 8th and 7th months. Finally we ask them to consider how tall these plants were before they were purchased (again assuming that they were growing at the same rate). Students use this context to see the pattern of powers and develop an understanding… 0, 1

Macy’s Star Rewards Points

…ent. For example, after working through several examples, they might notice and create the equation y = 0.1(x) – 25. From there they might consider equations like 100 = 0.1x – 25 in order to find the amount necessary to spend to come out $100 ahead. 8th graders and high school students can go through a similar process and focus more on thinking about inputs and outputs as well as the functional relationship between the variables. The activity can easily be extended to consider slope and… 0, 1

Cubs bury curse !

Wow! It’s been a long time coming. The Chicago Cubs just won the World Series! The last time they won the World Series was in 1908 (For some perspective, that is the same time the first car, the Model T, was produced.) Since 1908, how long has that been? How many players have waited? How many games or innings have gone by? How many days, minutes, seconds? In this activity students answer some of these or their own questionsabout how much of something has gone by since the Cubs won the World… 0, 0

Fantastic Beasts – What did it cost to make?

Clicking on this poster will show it larger in a new window. In 2001, J.K.Rowling (the author of the Harry Potter series) wrote Fantastic Beasts and Where to Find Them.

Thursday, September 22nd of this year will be the Autumnal Equinox. It is the time of year when the imaginary plane that might pass through the Earth’s Equator would also travel through the center of the Sun. At this auspicious moment the number of sunlight hours and night time hours are about the same all over the Earth. In the Northern Hemisphere we move into the Fall season.

Ask the class to consider these questions: Is this a good deal for patrons? What are the pros and cons? Will Olive Garden go broke? Is this good for the restaurant chain? Is the pass priced… 0, 0

Extra Point or 2-Point Conversion?

In 2015 the NFL changed the extra point kick distance to 33 yards and now teams have a tough decision to make, go for one or two points? The one point extra point is no longer a given with a success rate of about 94%. Teams can go for two by trying to get the ball in the end zone from the two yard line. Teams have been successful at two-point conversions in the past about 50% of the time. So we ask students, which does it make more sense to do? Given the data, should teams go for one or two… 0, 0
