Have all the kids line up in an open area. Designate one person to be Cupid and stand facing the group. The kids are supposed to do whatever Cupid tells them to -- "Jump on one foot," for example, or "Wiggle your ears" -- but only when he starts out by saying, "Cupid says." If he tricks them by not saying the phrase at the beginning and someone accidentally starts to do the accompanying action, that person is out. Speed up the directions and continue playing until you have one winner.
Test your student's memories by showing them a tray with a variety of Valentine's Day related items such as candy, paper hearts, a flower or a stuffed animal. Allow them to look at the tray for 15 seconds and then cover it up. Have each student write down as many items as he can remember. The student who has the most correct answers wins.
Tell your students about the history behind Valentine's Day. After the lesson, split them into groups and give each one a crossword puzzle with questions and answers that reflect what you just told them. The group that finishes first wins a prize.
Place a bowl of candy hearts in the middle of groups of three or four. Give each student a pair of chopsticks, show them how to hold them and allow them to practice for a few minutes. Set a timer for one minute and tell the students they can keep all the candy hearts they are able to remove from the bowl in that time using only their chopsticks.
Create bingo cards with the names of the students in place of numbers, and use candy instead of bingo chips. Place each child's name on an individual card and shake them all up in a bag. Draw the names one by one and have the students put a candy on the corresponding name on their cards. The first person to get a full row wins.
