These are mats I created to assess my kids on their knowledge of their letters. The letters are out of order to ensure true understanding and are in Comic Sans Font to match what they are learning. I either laminate or put the mats into a sleeve. I then have the student read them across and identify them.
I use the corresponding letter tracking sheet to mark whether or not they mastered the letter. I write the date of assessing into the column, and record if they mastered the letter or not. I have one of each of these letter tracking sheets in my assessment folder and flip to it weekly
