Mary at the Making Math Meaningfull blog has been presenting at the Exeter conference and has been posting stuff on her blog. Much of it she has posted before but on this one she talks about a marble rolling activity that can be used to model non linear relations. The premiss that students roll a marble down ramps of varying heights to see how far the marble will roll then use that data to make a prediction. Pretty simple but effective activity.Download the handout here and check out the post at the link below

I love the fact that on the last day of classes @MrOrr_Geek had his students do their own estimation challenges (in the style of @Mr_Stadel). Check out this post where he has examples of their videos from filling containers to covering stuff with stickies and then creating Explain Everything files to document them

And of course that means it's a good time to include a post from @Mr_Stadel on an activity he thought of (but hasn't tried) on how fast you can cover something with stickies. It covers rates and area (and possibly data collection and modelling). Check it out.

A couple of neat challenges from @DailyDesmos. Both of them use some of the advanced function notation features that allow you to use families of functions. One of them is linear and the other is periodic.
