…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

Thank you, mother and father, for all of those diapers

…more ambiguous. By using the activity in this way, students can engage more in MP1, MP2 and MP4. You can then go back and give some of the follow-up questions later separately. The original activity was written by and shared with us by Andy Fehlner, 8th grade algebra teacher in Newton, MA. Thanks for sharing this timely activity with us, Mr. Fehlner! Want to see student work? The Blog: “Teaching Math Rocks” changed the title of the activity for High School students and they have provided… 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.

Do teams that spend a lot win a lot?

…The NHL data sets itself up nicely for a line of best fit. We have two different activity guides. Data for both activities: BasketballStats.pdf FootballStats.pdf HockeyStats.pdf BaseballStats.pdf For middle school students, the lesson focuses on the 8th grade CCSS around scatter plots, association, outliers and clusters. Payrolls-vs-wins.pdf CCSS: 5.G.1, 5.G.2, 6.SP.2, 6.SP.5, 8.SP.1, 8.SP.2, 8.SP.3, HSS.ID.6 For high school students the lesson focuses on high school CCSS, such as correlation… 0, 1

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

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

Which of the Olympic sports do you want to watch?

Develop some understanding of the many Olympic sports and their various judging requirements. Should the Olympics only include performances that can be objectively measured? Greek gymnast, Eleftherios Petrounias Canoe sprintist, Mark de Jonga Wilmer Contreras, Equadorian weightlifter Michael Phelps, USA swimmer Ana Patricia Silva Ramos, Women’s Beach Volleyball Canadian, Megan Lane and Caravella Steele Johnson and David Boudia Kenya’s Rugby Sevens player, Mary Musieka (right) Print out copies… 0, 0

When organizing data is confusing? Venn diagrams for Rio?

There must be a lot of Olympians who haven’t brought home medals. Probably most of the athletes that went to Rio didn’t win anything. We couldn’t find any data about this. Can you deduce it? In this activity students try to calculate data that hasn’t been publicized by combining and sorting through information that is available in order to to draw a new conclusion. Which data is important and which is not? How many athletes have come home from the 2016 Summer Olympics empty-handed?… 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

Pokémon GO! I should have invested

Pikachu Pokémon GO is all the rage. News reports show people glued to their smart phones as they travel to nearby landmarks where virtual critters appear and need to be caught by throwing Pokémon Balls with a phone swipe. Well, at least those gamers are getting a little exercise. Let your students talk about gaming as they quantify how popular this has become, how much data is consumed by gamers, how much of an average data plan will be consumed by playing, and how they could have become rich… 0, 0

Do I have enough wrapping paper?

Clicking on this picture will show it larger in a new window. I have to wrap this box. In this problem based activity students first guess and then try to calculate whether they will have enough paper to wrap this present without taping pieces of wrapping paper together. Clicking on this image will show it larger in a new window. …with this wrapping paper …   Consider starting off the lesson showing the pictures of the box and of the wrapping paper.

Getting a new iPhone – which plan should I choose?

Clicking on image will show it larger in a new window. I want to get an iPhone8 and maybe change my service plan. Which of the above plans should I choose? Student pick one plan and consider the cost of the phone and plan over time. They make tables, graphs and equations. Consider allowing students to begin playing with the task without much initial instruction. Guide them with good questioning and teach after they have had time to grapple with these questions and construct new ideas.With our… 0, 0

Lighting the Olympic Torch

The 2016 Summer Olympic games won’t begin until on August 5th of this year but already the Olympic Torch has been lit and is traveling to the game’s site, Brazil, by 12,000 relay participants. Watch the lighting video and wonder how it was done … where is the match? How is she doing that? Describe what you see. Our animation is simpler than trying to demonstrate the reflections of a parabolic mirror. Let your students study the sunlight reflections and hypothesize why the focus of the mirror… 0, 0

Swimsuits – a drag?

Sammy getting ready for the start. To win in Olympic swimming, contestants have to be incredibly fit and have marvelous endurance and technique. Do they also need to consider the science of their motions and their equipment? Could your swimsuit, swim cap and goggles be holding you back? This activity is about drag and one method for calculating drag. Students observe what increases or decreases drag and how each element of drag directly, directly squared, or inversely affects a swimmer’s… 0, 0
