A number bond is a simple picture that shows how a number breaks into two parts. The whole goes in the top circle, and the two parts go in the circles below…
Twelve number bonds where the whole is 10. Your kid fills in the missing part. A great 10-minute warm-up for kindergarten and 1st grade.
A short video (from LampoFilm on YouTube) showing how number bonds are used in kindergarten through 2nd grade, with examples you can try at home.
