I like to keep my tracking system very simple and I use 5 x 7 sized index cards. I keep one for literacy and one for math. When working with students and noticing where they are excelling or maybe having some trouble, I make a note on the note card to help me with future instruction. This way also allows me to see trends in the data because I can re-read previous notes and find out if a student is still having difficulty with a concept or if they are being more successful at it. I can also use different color highlighters to show how a student is progressing overtime. I often use a pink highlighter to highlight any words that I have written, indicating a student is struggling, a yellow highlighter to show that a student is making forward progress, and a green highlighter to show that they understand the concept. If I see lots of pink or yellow highlighter lines, I know that I need to design an activity or an intervention to help that student with that specific concept. When a note card gets full, I simply staple a new one to the back so that I have an entire years worth of growth written on those notecards.

I highly recommend notecards with lines on them both on front and back, and dating each of the entries that you make on the note card. This will help you see the growth overtime and not get your observations and notes jumbled up so that they do make sense to you, and you are able to use the data.

This is an example of a standards based recording sheet that we use in K-4. This is a Kindergarten example, but it looks the same in K-4. We have also used them with sheets at the bottom for the different math domains such as geometry, computation and algebraic reasoning, data and measurement, etc.

During preplanning I set up a binder of the different benchmarks and digital programs (STAR, FAST [state test], I-Ready) before hand. Since I have the forms saved they are easy to edit if needed. At the beginning it was time consuming, but as soon as I had the system down it gets easier and easier. The Key is to find what works for you.
