…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

# What’s your favorite sport?

…to play to least favorite to play. Then they rank the same list of sports from favorite to watch to least favorite to watch. Students take the rank for each sport and plot the points on the grid. One example is pictured below. This activity targets 8th grade and/or high school to scatter plot standards and can be easily adapted for younger students, say 5th grade, to introduce or practice graphing in one quadrant.

# 4th down

…ut together in an article called “The 4th Down Study” by Brian Burke, a football fan and closet math enthusiast. We have two activity ideas. Younger students … 4th through 7th grade can try our graph reading activity. Older students … 7th grade, 8th grade, and high school can learn how this graph was created. Even if you teach older students, you might chose to do the elementary version. Here is a link to little video of a team recently going for it on 4th down (youtube link) And check out… 0, 1

…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

# Monopoly 2014

In the board game, Monopoly, does a property’s distance from GO correlate to its rent when you land on it ? Using Brian’s spread sheet (list of properties, distance from GO, rent and rent with properties) students create scatter plots. They graph points, draw lines of best fit, find average (X ,Y) values, judge outliers, and make predictions about new properties. As the teacher, you can choose to assign this activity to be done by hand or to be completed with the tools and skills of… 0, 0

# Columbus and navigation

The Niña Columbus Day is a bit of an enigma that used to be celebrated all through the Americas.

This post is about imagining sailing off into the West, into an empty looking ocean, to find what your captain believes is a good route to the Indian subcontinent? Sailing West was a huge navigational feat. Fortunately… 0, 0

# Pascal’s Triangle coloring and Probability

Working with Pascal’s Triangle offers some interesting and varied mathematics. We love to color and the end results are prettier than most math homeworks. Here is the second of 3 activities using Pascal’s coloring. Pascal’s Triangle and Probability – This activity could be used to explore the probability of coin tossing results. When the combinations get too complicated to list, students can use the numbers in Pascal’s Triangle. Introduction&day1.pdf Probability&Pascal.pdf CCSS:… 0, 0
