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?

Brian has spent too much time thinking about his leaf raking. He's worried about doing the job alone and 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.
Ravensburger says that if you spent 2 hours every day putting this puzzle together it would take you a year to finish.
What do you wonder?
Students surmise what the difficulty of a jig-saw puzzle entails and use rate calculations to estimate finishing times. They try to confirm whether doubling the number of pieces really increases puzzle completion time by a multiple of four.
Is the Electoral College vote similar to the Popular vote? The winner of the Presidential Popular vote (November 3, 2020) is not always the same as the winner of the Electoral College vote (January 6, 2020). In this activity students ponder how that could happen ... with data. 6.RP.A, 7.RP.A, HSF, HSS.ID.A
95% Confidence poll meaning - We've seen a lot of polls in relation to the upcoming Presidential election. What does margin of error, standard deviation, and 95% confidence actually mean. 6.SP.1, 6.SP.2, 6.SP.4, 6.SP.5, 7.SP.1, 7.SP.2,HSS.IC.A.1, HSS.IC.B.3, HSS.IC.B.4, HSS.ID.A.4
How well can you predict your candy haul? - Students consider how to determine their best predictions of their candy haul. The math ideas of measurement error and percent error are introduced. Students then predict their own Halloween candy collection numbers and compare their predictions to their actual haul using measurement and percent error.
Make a ghost costume from a sheet - In this activity young students can reason about the potential of a sheet, cut in a very defined circular shape, becoming a Halloween ghost costume. Notions of head diameter, sheet length, less than and greater than will all come into their reasoning.
Ooooo. Scary! This is a slightly didactic activity on vampire bats. We've given lots of interesting metric and customary unit facts and asked students to relate those sizes to more familiar objects. Simply enjoy the season with this slightly creepy activity ... metric and customary units, size and weight comparisons, and blood-sucking bats.
