Have I got your attention? This is a giant gummy worm. You can get one on Amazon by clicking here. I love to be able to grab my kids' attention in class and this was a great way to do it! All you need is some regular gummy worms and one giant gummy worm.
Here are some pictures of the lab!
The kids did a TON of math and were totally engaged with this one! I have another variation of this lab using gummy bears.
