What's a "Vibble Puzzler?"
Eh, it's a name, like the name of Charlie Parker's original song "Klactoveedsedstene," it's a sound, man, it's just a sound.
This is a collection of 12 vibble puzzlers for your kids to practice addition and subtraction while engaging in problem solving. Just to make them really annoying (as if the fact there are 12 different ones, and they come in black/white/grey and color is not enough) I've also included 2 extras that can only be solved by using either negative numbers or double digit numbers. HA!
