Math Coach's Corner Place Value 'I Can' Cards and Choice Board - can make one for kids to practice other skills - like make 13 using cubes/on 10 frames/write it etc. 3 in a row is a winning tic tac toe
Score sheets, a deck of cards, and pencils are all that are needed for this fun decimal place value game! Perhaps a modified score card (with just thousands, hundreds, tens and ones) could be made for students that haven't learned decimals yet.
