crossing over

I love it when subjects overlap.  Noah likes biology but hates math.  Today I found a way to bring biology into algebra, and he liked it!  I was teaching him how to multiply binomials.  I taught a vertical method that he wasn't fond of, so I taught a horizontal method that he liked better but still wasn't really connecting.  I remembered that he liked the Punnett squares from our study of genetics, so I brought that into our algebra lesson.

Just replace the alleles with the terms of the binomials, and there you go!  He understood it and actually said it was fun.  :)
