I'd definitely have students check all their skittles in the future. <br /><br />I think having them estimate the number of skittles led to them thinking it was linear. I'm not sure how much they actually looked at the shape of the data. <br /><br />I think I'd do a lot of things differently with this activity in the future.Sarah Carter (@mathequalslove)https://www.blogger.com/profile/11839095945000612533noreply@blogger.comtag:blogger.com,1999:blog-1091979517567705761.post-19813867842169390412014-11-30T14:45:18.865-06:002014-11-30T14:45:18.865-06:00Sarah,

I poured a small snack size bag of like 12 and at least 3-4 were missing or VERY hard to see. And 2) Do you think the shape changes the relationship? I noticed that your kids concluded linear more often and I was wondering if it was because the actual data looked more linear than exponential. <br /><br />I've always used M&M's but I have a kid with peanut allergies and would like to try to use Skittles instead, but the two questions mentioned above make me a little nervous. <br /><br />Thank you for your awesome blog!Anonymoushttps://www.blogger.com/profile/15353182832846438797noreply@blogger.comtag:blogger.com,1999:blog-1091979517567705761.post-22827871640075684192014-05-06T20:07:47.845-05:002014-05-06T20:07:47.845-05:00Jaclyn,

Since we rushed through both activities in the same day, we used the same candy. I like the idea of using the pennies! It might work to use candies one day and pennies the next. <br /><br />Thanks for sharing!

Or do you have two sets of candies, one for each activity?<br /><br />This reminds me of a similar activity done with pennies, modeling the half-life of an imaginary element "Lincoln-ium" that I've done with Chem and Physical Science classes. Start with a 100 pennies in a shoe box, cover and shake for 10 seconds, open and remove all coins not displaying Lincoln's profile. Repeat. Use data to create a decay curve and find the half-life, letting 1 second=1 day or 1 year.Anonymoushttps://www.blogger.com/profile/00725419973292498229noreply@blogger.comtag:blogger.com,1999:blog-1091979517567705761.post-2030337765823707872014-05-02T12:09:19.921-05:002014-05-02T12:09:19.921-05:00Hi Sarah,

I coach HS teachers and this activity got me really excited. In 5 years of teaching, I haven't seen this exponential activity and LOVE it. I've adapted your investigation to be a mix of what I see here and another version I found online. If you're interested, I'll send you what I did ! <br /><br />Thanks! Have a good day! <br />Jaclyn Anonymoushttps://www.blogger.com/profile/17895790111224128895noreply@blogger.com
