I bought two sets of these super cute magnetic wooden
numbers for less than $1.00 on Amazon
I then buried them in a plastic shoe bin filled with rice:
The girls had a great time digging through the rice finding numbers
to match to their identical counterpart on the table.
My 4 year old said that next time it would be better if we had groups of items
set out on the table and she would find the number that matched how many were in each group.
I then set out a bunch of different measuring cups and spoons on a sheet on the floor.
We explored how many scoops of the various cups it would take to fill one whole cup with rice.
