What I consistently end up keeping every month is the name tags and the journals. The reason I keep those types of things is because it makes it easy to actually see the changes in their thought patterns, gross and fine motor skills. You have writing, math, reading, letter recognition, number recognition and free drawing located in name tags and journals.
I know that some people do not like journals especially journals that have pictures and words inside of them, but I love the journals from Mother Goose Time. I do not use the suggestions at the front because I am using the journals as evidence. It CAN become bulky but the fact that the parents have something easy to look at and can easily see improvements from month to month without me having to show off my fancy education and vocabulary is the most important thing. Parents do not need fancy bells and whistles to understand if their children need extra help or if they are improving. They need a teacher who cares enough to sit down and explain how the work sent home can show the improvements in their child and can help explain what can be done at home to help the children advance forward in their education. Collecting the same type of work every month for the next year can be an accurate timeline in the progress being made by the child.
Let me know what you use for assessments through out the year.
