Collect toilet paper tubes. If you would like you can spray paint them. Take a knife and make four slits in the toilet paper tubes as shown. Take craft sticks and have the children insert them into the slits to create a fence. These can be put together and taken apart to make fences.
Print a page for each child. Have the children roll a die and identify the number on the die. Have the child find the corresponding number on the cow and color it. The first one with all the cow colored is the winner.
