A cool idea: Throughout the day I drew out a name and that student got to pick a balloon for us to pop. Inside each balloon was a different 100 activity for us to complete. Some examples of things we did are... 100 jumping jacks, draw 100 shapes, count by 2's to 100, do 100 sit-ups, touch our nose 100 times, clap our hands 100 times, blink our eyes 100 times, etc.
at back to school night put apples on a tree....bees..whatever your theme is write things you need. Parents are so generous and I always start the year with tons of extra supplies. They usually bring the items in and attach the bee/apple to bag.
