Class roster by period on a lanyard; easy attendance in case of emergencies -- good to put in a sub folder for subs to wear all day, but make sure to keep the list updated! (check to see if you can write on clear plastic cover with a Sharpie and erase with a dry-erase marker; if so, you can use Sharpie to cross off names of anyone absent)
Contraction Surgery! Index cards with two words (like "she" and "will") and then the kids cut off the "wi-" and then use a band-aid to attach "-ll" to the other card. The band-aid is the apostrophe! So cute and memorable!
