I love the idea of using dry erase markers on the desk to practice rounding. What a great way to get kids engaged. This site also includes a couple of good rounding rhymes to help students remember the rules.
I have my students underline the place value being rounded too, but I also make them box the number that tells them if the number rounds up or stays the same. 5 or more, raise the score. 4 or less, let it rest.
