This is a rounding with playing cards 1-9 station game great for place value and estimation units. I have the partner groups have this game board and a deck of cards. The students then deal out three cards and flip them over. They can make any number they want or have them make the biggest number one time and then the smallest number the next time. Then have them round it to the place value it says. One side is for 3 cards (up to hundreds) and the other side is four 4 cards (up to thousands).
Let me know your feedback and if there needs to be something done to correct any mistakes! :)
