I went searching the internet for something to help my kids learn their Doubles Facts. I found several versions of this rap, but none of them went higher than 8. I kept some words the same and some I changed and I made it go up to 10 + 10.
In my class, we chanted the chorus, then 2 doubles ( 1 + 1 & 2 + 2) then the chorus again and kept going to 10 + 10 and ended with the chorus.
Hope you like it.
