Year 6 Word Problems - individual cards
A selection of illustrated word problems (the text for them taken from the Leics site) that can be printed off, cut up and then used. My class used them laminated and had a competition - 1 point for the correct calculation(s), 1 for the correct answer. In theory they get harder on each page, but that is not a hard and fast rule. Doing the problems this way seemed to motivate them more than a worksheet or book.
