barbecued-smoked-turkeyHow should I cook my turkey? - Students judge timing, cost, tastiness, and quantity necessary as they plan for the feast. 4.MD.1, 5.NBT.7, 4.MD2, 6.RP.3, 6.NS.3, 7.NS.3  Great video on a deep frying fire with William Shatner.

Lots of Cranberries - In this timely activity, students learn about how cranberries are grown and harvested; estimate their size and quantities; and see what they can deduce from published statistics. 5.MD, 6.RP, 6.SP, 7.G.B, 8.G

Not enough mashed potatoes - Use Brian's famous mashed potatoes recipe to practice changing decimals to fractions; calculating ingredient measure for various-sized Thanksgiving servings; have students explain their reasoning; and to have students figure out how many servings 7½ pounds of potatoes would make. 5.NF.6 , 5.NF.6 , 6.RP.1 , 6.RP.2 , 6.

As the Macy's Parade returns to public viewing, here are two balloons that Macy's artists have added. Can you figure out their dimensions? Macy's give their dimensions in bicycle lengths, taxi widths, and stories tall.  Students use proportional reasoning in this short, but happy, activity.

Shopping season already!

We used to see holiday sales right after Thanksgiving but, surprisingly, holiday shopping has already begun. Sales are advertised everywhere.  Students will be able to add some understanding and analysis to those shopping trips after calculating savings in dollars and percents
with this timely investigation.

Veterans Day 2021

On Veterans Day we honor the men and women that have served in the Armed Forces of the United States.  As of the the 2010 Census, there are 18.8 million living veterans. We found these maps that show where veterans live in the U.S.

What do you notice and what do you wonder when seeing these maps?

What if I got more people to rake my leaves?

Brian has spent too much time thinking about his leaf raking. He's worried about doing the job alone and thinking about how long the job would take with different numbers of rakers.

In this activity students see the inverse relationship between number of workers and time to complete the whole job. They graph hyperbolas and consider how long the extreme condition of zero people raking might take to complete the job.  

End of Daylight Savings time confusion

An interesting intro to this activity might be this Youtube explanation that a young man presented about standing on the boarder of Navajo and Hopi reservation and time weirdness.

In this activity students try to figure out how time settings will change as they move from place to place and what variables are involved in the daylight savings time shift. Day length? Latitude?
