…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

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.

## 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?

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
