1. Hokey-pokey: Sing the "hokey-pokey' song ("You put your right hand in, you take your right hand out, you put your right hand in and you shake it all about..."), and put the correct body part inside the hula hoop. You can do this with the hula hoop on the ground, or hold it upright.
2. Ring Around the Rosies: Have everyone hold the hula hoop and spin around the circle as you sing "Ring around the rosies, a bucket full of posies, ashes, ashes we all fall down" (or a variation if you don't like singing about the plague). The girls really liked the falling down part.
3. Up and Down: Hold the hula hoop and recite a rhyme that has Up and Down in it. When you say 'Up', lift the hula hoop up, and for 'Down' lower it to the ground. Examples are "The Grand Old Duke of York" and "Dickory Dickory Dare, the Pig Flew Up in the Air".
4. Hula Hoop Jump: You could make up a variety of games involving jumping in and out of the hula hoops. If you have more than one hula hoop, line them up and jump from one to the other. Try placing them further and further apart to see how far you can jump.
5. Simon Says: Play traditional Simon Says, but using the hula hoop as a prop. "Simon says... jump in/out of the hula hoop, lift it over your head, put your hand in the hoop, balance it on your foot, etc.."
6. Bean bag / ball toss: Practice throwing balls or bean bags through the hula hoop. You can try holding it in different way - horizontal like a basketball hoop, vertical, or even placed on the ground.
7. Circus hoop dive: Have the kids dive through the hoop. Alternatively, they can teach their stuffed animals how to dive through the hoops. For extra fun, you can tape colored tissue paper around the edges and pretend the hoop is on fire.
8. Hula Hoop Spin/Roll: Let the kids experiment with spinning and rolling the hula hoop. Our hula hoops make a cool sound when they move, which adds to the fun.
9. Hula Hoop Catch: Spin or roll the hula hoop and challenge your children to catch it. This activity builds great hand-eye coordination and is sure to generate lots of giggles.
10. Horse-Drawn Carriage: This was the kids' favorite activity. Both girls went into the hula hoop and one pretended to be the horse while the other one was the passenger. They walked/ran all around the house like this. They even convinced Daddy to be the horse for a while.
There are definitely more involved hula hoop activity ideas out there, but these ten are just perfect for the active toddler thru kindergarten age group. Enjoy!
UPDATE: I was so inspired by how much my kids enjoyed early learning games that I created the La La Logic Critical Thinking Curriculum for 3-6 year olds, which includes online brain challenge games, printable worksheets, enrichment activities and more!
