Is there a general way to figure how much its going to cost you (and your friends) to go bowling? Should you pay per game? Or bowl per hour? Don't forget that you'll need to rent shoes. Students work with linear relationships and do some problem solving - estimating the cheapest way a group can bowl, all within a bowling context.

Who do we honor? - What people or events are included in the National Mall monuments? Students use fractions or percents to decide what they can notice about those we honor. 3.NF.1, 6.RP.3

Monuments most visited - Students analize the visitor statistics of the National Mall and make observations. 6.RP.3, 7.NS.3

Which should we order and why? Two 12-inch pizzas or one 18-inch pizza? Which will give you more pizza? More crust? Which is the better deal? Let's do the math!

Now the that season is underway let’s check in on how Cleveland and the Lakers are doing since LeBron changed teams.

LeBron is arguably the best player in the NBA and a tremendous addition to a team ... a real difference maker. He began his career with the Cavaliers, then moved to the Miami Heat, then back to the Cavaliers, and now he's moved to the Lakers.

In this activity students read graphs and use measures of central tendency as they compare the records of the Miami Heat, the Cleveland Cavilers, and the Los Angeles Lakers with and without LeBron. How many wins per season can we expect from the Lakers now that they have LeBron and just how many wins is LeBron worth? Give students some time to think about & discuss ways that we can measure LeBron's effect on the performance of a team. Here is a link to a video clip about Lebron moving to the Lakers that you might use to introduce the context of this activity.

Brian May, the lead guitarist of the rock band, Queen, is also an astrophysicist and one of the science team collaborators of the New Horizons space program. The video below is the song that he wrote to celebrate the New Horizons' latest achievement ... flying by Ultima Thule.

You and your class might begin this activity with a viewing of Brian May's just-released song and a class discussion about the New Year's day fly-by.

On January 1st, 2019, the New Horizons spacecraft passed close to Ultima Thule, a Kuiper Belt object that's a billion miles beyond Pluto. That milestone marked the most distant celestial object that we have ever been able to see close-up. In this activity student do some rate conversions to try to understand the delay in knowing that the mission was a success.
