Stacking Jack

Act One: Check out the video slide show.  What questions do you have?

The Activity: Stacking Jack

Suggested Question: How many different ways can I stack Jack?  That is, how many different color arrangements are there?

If I wanted to take a picture of every possible arrangement how many pictures would I need to take?

Really big shoe

Brian and his son were doing some shopping when he found this shoe.  Egad!  Could that be someone's real shoe?

In this activity student need to use a shoe size chart, patterns or linear modeling to try to figure out what size this shoe must be.  Then they try to estimate how tall this person must have been.  Whoa!

The cost of going back to school

School-gear

Back to school spending is huge and students might not appreciate what it costs to send them back to, essentially, their job of learning.  In this activity students decide what equipment and supplies are necessary, estimate how much that will all cost, confer with groups or partners to refine their lists, and then research to find out more accurately how much it will probably cost to send them back to school.  This activity could be used for students in upper elementary school all the way to high school.  It offers an opportunity for kids to get estimating, researching, reasoning, calculating and communication skills honed for the coming year.

S’mores

No joke. Saturday was National S'more Day.

Thanks to Maggie Hefferman, Newton, MA educator, for the idea of this post.

To help you celebrate this strange new holiday, we've asked students to do a little math to help quantify what is reasonable.

What’s the answer?

Math doesn't usually create a buzz on Twitter.  This past week this post did just that.  People argued online about whether the answer was 16 or 1 and proceeded to insult each other's intelligence in doing so. Use our write-up to bring your students into the discussion and see how varied their reactions and conclusions are?  Enjoy! This is a current event!
