Inside a kindergarten classroom with Augustana students

## Exciting Discoveries!

This week in Number Sense we incorporated the week’s math focus into our work with the students. The week’s focus was centered on the numbers 11-20 (writing and creating ten frames). For many weeks the students have been able to count past 20. I was a little surprised to discover that while the students knew the sequence of words, writing them introduced a whole new set of struggles. Once I picked up on the fact that students were having a difficult time producing the numbers on their own I decided to use the Line Em Up app to show them what the numbers looked like. Many of my students needed a little guidance in putting the numbers in order on the app from 1-20. Once they had the line complete I asked them to look at the numbers and see if they noticed any kind of pattern. I was extremely happy to witness several students point out that the numbers “started over” but with a 1 in front of them. We took this new discovery and tried to apply it to writing the numbers on a white board. It was great to see the students apply this knowledge and use it to write the numbers out. They still struggled a little but they were able to reproduce the numbers with a little prompting. One of the questions that I asked to help prompt students was: “What number comes after 12?” and “If 12 is a 1 and a 2 what do you think 13 would look like?”
I was also able to move forward with some of my students in regards to the dice patterns. I have noticed some students were getting bored with drawing the dice patterns on white boards so I introduced them to an app called Tric Trac. I have used this app before with my first grade clinical class and I thought it may be too advanced for the kindergarteners but figured it was worth trying. To my surprise (and delight) several of my students rose to the challenge. Tric Trac involves rolling two dice. You then count the dice (for example: 6 and 3) the total number (9) is the number you then have to choose to equal your sum. At first it is pretty basic because you simply select the number of your sum. However, after a couple of turns you must select several numbers to equal your sum. This was a roundabout way for me to reintroduce the concept of “making a number” and allowing students to recognize that different numbers can be added to create the same sum.
