Bears in a Cave

We have been learning our Friendly Tens in kindergarten (addition to ten - 1 and 9, 2 and 8 etc). A great way to practice these numbers is to play the game called Bears in a Cave. Bears in a  Cave is a simple game using a cup and ten objects.  The counters can be any smaller items that fit under the cup or bowl.  One player closes their eyes while the other one puts a number of objects under the cup.  The first player has to calculate how many items or objects are under the cup and says the corresponding math sentence.
