"Bigger Bottom, Better Borrow" is a 4 minute, karaoke style video, that students can sing along with to help learn basic subtraction, with borrowing. I wrote this song as a request by the second grade teachers at my school. Third grade also uses it.
It integrates music, math, reading, and video animation. You can use it as daily practice, part of a lesson, subtraction review, PE warmup, clean-up song, or just for fun.
The video can be played on an interactive whiteboard, computer monitor, iP
