This song is so fun, even my teaching neighbor and I were singing it practically every day for a week. It's a great little way to teach your students about subtraction! The song is pretty long and includes word problems. After we had learned and sung the song for a few days, I gave my kids some white boards and each time the video came to one of the word problems, I would pause it and the kids would write and solve the number sentence on their own. Then I'd continue playing the video so they could check their work and see if they were right!
I began to notice that it helped my kiddos start to solve their subtraction number sentences more quickly and more were able to solve it mentally without having to draw a picture when we got to our independent practice.
I really love using all of his videos in my kinder class! They are so fun and fantastical!
