Singing and Adding by 9s

Have Fun Teaching

This educational music video features a high-energy pop song designed to help students memorize addition facts involving the number 9. Through a catchy melody and repetitive structure, the song guides listeners through addition equations starting from 9 + 1 up to 9 + 15. The format utilizes a "call and response" or continuous chanting style that encourages active participation and vocalization of math facts. The content focuses entirely on arithmetic fluency and mental math strategies for adding nine. While the song does not explicitly explain the "add 10, subtract 1" strategy, the sequential ordering of the facts allows students to naturally observe the pattern where the sum's ones digit decreases by one as the addend increases by one. The rhythmic delivery helps cement these number pairings in long-term memory through musical association. This resource is an excellent classroom tool for auditory learners and serves as a perfect transition activity, warm-up, or brain break during math blocks. Teachers can use it to build fluency without the stress of timed drills, allowing students to dance or sing along while internalizing number relationships. It is particularly effective for early elementary students working on single and double-digit addition mastery.
