When it comes to party planning, nobody does it better than One Charming Party. Here is the Valentine class party they shared on their blog - awesome!
This site shares party hat ideas from paper plates - for every holiday!
I know I shared Bingo the other day, but I had to include it here since Bingo is my go-to class party game if there is extra time!
For older classrooms, these Mad Libs are perfect!!
Make and Takes is a great blog with tons of good ideas - she pooled together these great Valentine class party ideas:
Letter Match - pair up upper and lower case letters - great for lower grades!
Heart Lei made with yarn, straws and hearts!
Giant Tic Tac Toe - use posterboard and handmade felt hearts for the playing pieces. Make a few and you can have 4-6 kids playing at a time!
Three pipe cleaners and each kid gets a new pair of glasses to take home!
Put these together and the kids can put theirs together and then trade with another student for even more fun!
