This week we started to review our teen numbers and move into place value. I’m not sure about your kiddos, but this has always been a difficult concept for my Kindergartners!
This year instead of jumping straight into place value we are taking time to review the teen numbers with an emphasis on place value. We first introduced teen numbers before Christmas so this is a second exposure in our curriculum.
This year we started out by simply representing the teen numbers within 10 frames.
I gave the students a ten frame template and counters. I emphasized A LOT that teen numbers will always consist of 1 group of ten- hence they should always have 1 completely filled in ten frame. We worked on this for an entire math lesson. I had a spinner on the smartboard to make it a little more interactive. The kids did pretty well for their first day.
We then moved on to recognizing again that teen numbers have a group of ten. I introduced this by giving all of the students one “ten stick” built out of snap cubes. I chose to not give the students actual tens sticks {place value sticks}. We will possibly move into those once we introduce actual place value activities within our curriculum.
On this first day students worked with partners building the teen numbers with their ten stick and additional “ones” snap cubes. Above you can see this student has made the number 13. As we built each teen number I would call out this prompt and have the students fill in the blanks, “13 is __group of ten and ___ ones.”
{below you can see another student’s example of the number 19}
We then started to go into one teen number each day. Yes this is turtle pace but for the students to get a real understanding of what a teen number is you need a slow pace. We review with the above activities as well as the interactive games {listed below} each day. We also practice the teen number for each day using Growing Kinders packet, Fun with Number Part 2 11-20 {see below for link}. This is a wonderful packet for practicing teen numbers!

I posed the following question to my kiddos this week….
They had a lot of great ideas and a couple had figured the answer out quickly! If you haven’t posed this question to your kiddos — please do and let me know how it goes. It is so rewarding to see them think through a problem…they love a good challenge!
The above image shows how I explained the answer to why teen numbers start with a 1! I wrote the teen number on the white board. I then held up the ten stick and ones cubes that we had worked with the 2 previous days. I asked, “how many group of ten did we have?” The kids immediately answered with 1. It was a definite “Ahh Hah!” moment.
One of our best review times is in the hallway! Teachers like to multi task and why not at the restroom? As the kids wait for the restroom we review tasks that we’ve covered in class. With teen numbers I have the students simply state the number or have the students use the following prompt, “13 is __group of ten and __ ones.” Click below for a freebie teen number flashcard set!
I have a few versions of Prove It! practice sheets. This is the place value version- a simple but effective way to get the keep to go “deeper” with their thinking. The packet comes with 2 versions of practice sheets.
Version #1: The student must draw the teen number using a ten stick & ones.
Version #2: The student must represent the teen number using the ten stick and ones displayed for them.

these are great ! we are starting place value week after next and since i'm in charge of mapping out our math lessons for K i'm excited to get these ideas! thanks for sharing! love ya!
LOVE the interactive games…can't wait to share with my teachers. Thank you!
