The school supply thing is a bone of contention with me. When my little one started kindergarten we got a list and I bought everything (including tissues, hand sanitizer, ect) then found out except for the folders, everything went into a communal supply area. That meant that my hard earned money went to supply kids whose parents didn't (and I have noticed that the lower income families buy the supplies, the higher income families do not grrrrr)> Last year I bought the supplies on the list sent home a week before school started..then she comes home with a completely different list from her teacher so I had to go back out, again, and rebuy stuff but at least it wasn't communal (altho my sweetie will give her classmates the shirt off her back so I ended up replacing stuff often. Thank you Dollar Tree!). This year I sent her on the first day with some pencils, glue sticks, a sharpener, and a folder because I didn't trust the list they sent home..and that was the list to be used!! And I always have to buy the binders for her and they were never used last year..they got sent back in for this year. Some teachers are very SS with expecting the parents to supply the class with everything..no, I will make sure my child is well equipped but as I have been off work for a year I will not supply other kids with supplies. If the parents can't afford it, the school social worker has resources to help them out, and if parents are too lazy or don't want to well, their kids are not getting my kids supplies.
As far as the white boards and markers for them, my DD has been using them since K (she is in 2nd now) for math. Instead of practicing on paper where they erase alot and tear the paper and waste it they just use the white boards. I think it is a great idea and the dollar store has the boards and markers.
