Just got this off teachers.net from Jessica. Thought I’d share as I plan to use it.
Draw mountains!! (I hope this makes sense):
at the bottom left of the mountain is 30, the top is 35, and
the bottom right is 40. If you’re hiking up the mountain
and you stop at 34 and you accidentally fall, where will you
fall? (down to 30). If you hike all the way up to the peak
and you’re at 35, but you accidentally fall, where will you
fall? After all your hard work you don’t want to fall back
down to 30-you’d fall on the other side to 40.
Thanks for the idea. I tried a variation with my 3rd grader and it helped!
