For our math workshop this week, we explored teen numbers. Our kindergarteners are adept at counting, and many have shown their counting skills for their medallions already! However, it is a critical piece of math competency to decompose numbers, as in recognizing that 10+1 is the same as 11, 10 and 5 is same as 15, etc. With teen numbers, it also helps children work their way around place value and understand the abstract concept of tens and ones.
We used a ten frame similar to these ten frames to break down numbers 10-20.
We began teen number booklets, thinking in sets of five or "5 groups" to build and record numbers 10-20.
At another station, students practiced matching ten frames to teen numbers.
But our favorite station was number match! One student covered their eyes, and their partner filled the ten frames to a number between 10 and 20. Then their partner had to quickly identify how many and record it on the table. It was definitely a lively game for all!
