Mini Kagedekoration

The foam slices snap together so neatly that my kids figured out the fractions part on their own, and the air-dry clay piping nozzle actually works like the real thing. I was skeptical about mess, but it's all contained and dries solid. We've used it three times already this week.

Bought this for my 7-year-old and she's been obsessed with the foam cake slices—she finally gets why halves and quarters matter. The air-dry clay is surprisingly easy to pipe through the nozzle, and cleanup's a breeze since the foam doesn't crumble everywhere.

The piping nozzle actually works with the clay, so my kids can practice real techniques without the frosting mess. The foam slices are sturdy enough to rebuild over and over, and the fraction lesson is a sneaky bonus.
