I added just enough water to make it crumbly and hold its shape when squeezed.
I poured the snow into our play tray, and gave Bo the penguin erasers. At first, she just played with the penguins in the snow, but after a bit, she came up with the hide and seek game.
She would bury a few penguins in the snow, then pretend that another penguin was finding them.
I turned this activity into a counting activity by having her hide and find a specific number of penguins.
We took turns hiding one, two, three, four, or five penguins (she is currently only counting up to five, but we had about 30 erasers, so you could count much higher than that if your preschooler is ready).
After counting to hide the penguins, we switched the game up a bit. I would hide the penguins secretly, then tell her how many I buried.
She would then count the penguins as she found them until she counted up to the number I had hidden.
We both thought this penguin sensory bin activity was a blast!
