I've finally added this game to TpT! The reason why it wouldn't load was because the file was over 50MB! I've split the file into 2 - buy the game here and download the rules and monster counters here.
The game focuses on rounding 3-digit numbers to the nearest ten and hundred. It is tabloid/A3 size so I get them printed off at school. Or you can print them to A4/letter size (over 2 pages) and make a file folder game. These are great for centers or math work stations.
It comes with a 2 versions of a 3-digit board for students to check answers if there are disputes. This one shows the 1 hundreds, students just replace the 1 hundred with the hundred they landed on and use it to work out whether they round to the 10 or hundred the number has, or the next one. The other version has a '_' where the 1 hundred is - students just insert with the hundred they landed on.
Students have to collect 5 green and 5 yellow counters (or monster cards below) to win the game. They collect 1 yellow counter for rounding to the nearest 10, a green one for rounding to the nearest hundred.
