Yesterday in my 2nd grade math class, I introduced the concept of rounding to the nearsted ten. I was suprised how confused many of the students were, even while using a number line. I woke up at 4:45 this morning with an idea: a game to practice rounding. This is what I came up with:
The first student draws two cards from a deck, and makes a two digit number. They then write that number down, as well as the nearest decade number, ten, to practice their rounding skills. The students played with a partner, and I found that the peer support they received while practicing made a huge difference. Each student had their own worksheet, but they wrote down both player's numbers. The kids had fun and did not want to stop. I think I will use this for a math warm-up activiity once in a while to keep skills sharp. This game could also be played with dice, or by drawing three cards.
