I have a kindergarten student who has come a long way and is not low enough to be considered for retaining. But, he is my lowest and really struggles because he cannot retain a lot of what I teach him unless I review with him everyday. I am really worried about the summer. I am afraid that he will forget everything. First grade is going to be tough on him as it is. Should I send anything home with him on that last day of school? His mom has three other kids and I don't know if she would even use it. Any advice is very much appreciated!
