KinderMath: Decomposing 11-20
This lesson is the foundation for students to compare teen numbers. We will review that a teen number is 10 and some extras. We will then work on comparing the “extras” before we move into comparing teen numbers for their numeral only. Using a magnetic Ten Frame, I will show a full ten-frame and ask, “How many do we see here? 10! How did you know that? What if I do this? (The magnets will be moved outside of the ten frame but still in a group.) How many do I have? I still have 10. Just because I moved them outside of the ten-frame, there are still 10 because I didn’t add any or take any away. Now what if I do this?” (I will add 3 additional magnetic circles to the OUTSIDE of the filled ten-frame) and ask, “How many do I now have? 13! You knew there were 10 and counted on...11, 12, 13.” I'll write the number 13 on the board and explain that the 1 stands for ONE group of 10 and the 3 stands for the EXTRAS. I will continue the same routine with the numbers 12, 14, and 15.
