Here are three different versions of a place value game. This game involves practicing tens and ones with ten frames and with base ten blocks. There is also a blank version to alter however you deem fit. I used a triangle to help students see that the digit in the tens and ones place are "pushed together" or funneled closer to create the number. Then by building, showing, and expanding it they gain knowledge in what that number is truly representing and why that triangle strategy works. Before you know it students won't be counting each object or skip counting but rather going straight from digits to numbers with full understanding of what that means and why.
When building a deep understanding of number sense it is best to start with ten frames over base ten blocks as younger children can make more sense of a ten frame prior to making sense of a base ten rod. Playing similar games with different tools is also very helpful in building multiple representations....
