1 Introduction - 10 minutes

This is an activity that I use as one of my math stations, so there is not a formal introduction to this lesson. The stations are very briefly discussed at the beginning of the week. This takes approximately 10 minutes. I am fortunate to have a para-pro and parent helper each day of the week during my station time, so  they are able to assist students, keep them on task, and work with them at stations. With 3 adults in the room, instructions are able to be brief, as anyone who is having difficulty will be noticed. My station activities always target skills that we have previously learned.

During station time, my students are broke into 2 groups (12 students in each group- totaling 24). On Mondays & Wednesdays, group 1 is working on stations, while group 2 is using technology. Technology includes i Pads, lap tops, and the smart board. On Tuesdays & Thursdays, group 2 is working on stations, while group 1 is using technology. Fridays are free choice. All students use technology and re-visit any of their favorite stations from the week. I have included a picture of my schedule that is displayed in my classroom.

2 Christmas Tree Ten Frame - 15 minutes

In this Christmas Tree Ten Frames Math Center activity, students are given a set of cards that consist of 2 ten frames. Children add the digits from each ten frame and put a clothespin on the correct sum. I found this station on Teachers Pay Teachers for free from Kamp Kindergarten. I print several sets, cut, and laminate for stations.

Understanding that numbers are composed of ones and tens is important to set the foundation for mathematical learning. Ten frames develop a strong number sense, and allow children to have a visual image of numbers.

I have included video of a student who is on the right track!

Something's Missing
Checks for Understanding

What I am looking and hoping for when my students use ten frames, is automatic recognition of 10. I want students to see a filled ten frame, and think "oh, that is 10", without having to count each individual space. When I see a student individually counting each space in a ten frame, I know that I need to work more with them on developing good number sense. I have included a video of this.
