I started working on some Valentine's Day themed math centers today and I got one finished! It is pretty basic but a good review of rounding and has cute graphics! Students will work in pairs to round numbers from the tens place to the millions and find the card with the answer that matches! First person to comment gets a free copy otherwise you can check it out at my TPT store. I plan on making some fraction, decimal, measurement, geometry, multiplication, and division centers as well....I better get busy!
