Here is one of my recent Pinterest finds http://www.teachingblogaddict.com/2012/05/fun-way-to-assess-students-learning.html
As you can see it is a versatile activity that can be used to work on a variety of skills. Students can play on a dry erase board or you can use cards so students remove cards instead of erasing problem. One student calls out an answer while another erases the problem. You could play this same game with addition, subtraction, multiplication or division. One student calls out the answer while another takes the card away. This will also work for numeral recognition. One person says the numeral and other person erases. Combinations to 5, 10, 20, or 100? One person says a number and the other person erases the number that will make the target number.
