This is a board game to help students practice rounding numbers up to the millions place. It is aligned to Common Core State Standard 4.NBT3. It includes a board, directions, 8 green snail cards, and 24 pink snail problem cards. The file is sized to print the board 8.5 X 11 in. paper for easy printing, but I would encourage enlarging it to ledger or legal size paper for easier playing. The directions encourage students to check each other so that all students are engaged during the game. This is great for a small group or center activity.
