This was such an easy activity to set up, but it was really fun to play. I cut out a mouth shape for all three of us, drew some circles where the teeth should go, and printed off a dice pattern. I figured out that if you just type 'dice printable' into Google, you'll find several options. I chose to stick to numbers 0-3 because my little guy is still working with basic counting. Surprisingly, no one every rolled a 0. I wonder what the odds of that are. I'm sure I could figure it out, but I'll save that math lesson for when they get a little bit older. Anyway, we each took turns rolling the dice, and whatever number came up, we glued that many marshmallows on our 'mouths'. Both kids were dying to sneak a few marshmallows, but I told them they had to fill up their whole mouth first, and then they could keep rolling for marshmallows for their real mouth. That made it all the more thrilling when they finally filled up their whole mouth.
I didn't snap any pictures of the mouths folded, but we all three got the giggles chomping our mouths and shouting, "om nom nom nom nom!".
