Here's a football math freebie for you. I use this as a math challenge on our January homework menu, but it's great for a math warm up in older grades and a challenging fast finisher for those younger guys. Hop on over to my blog and check it out.
I've been teaching for thirteen years -- one in 5th, one in 2nd and eleven in 3rd. When I'm not thinking about, writing about, or looking up ideas for teaching, I'm hanging out with my hubby in Boulder or with my minpin Lily (the cutest dog ever!) on the couch in front of my laptop and a good HBO show.
