I created this page to use with my Kinder EL's when focusing on the vocabulary around "decomposing" numbers and learning that teen numbers contain only 1 ten, and then some ones. I presented this as a part of a slide show of lessons for the week, with a preview of all the teen numbers listed. I displayed one number bond and the ten frame and blank ten frame, and modeled the decomposing process, letting kids pick a teen number, and then let a few kids try on their own, before setting kids loose to pick 4 teen numbers of their own to decompose. Those who finished quick, I would turn the page over and then "challenge" them with numbers like 34, or 56, or 78, just depending on the kiddo and their level of understanding. This could be used whole class, small group, as a math center, or for an individual as well.
