A randomizable worksheet aimed at helping children improve their understanding of basic addition. At the simplest level, the student is asked to draw 5 hats, and then another 2 hats, and then count up how many there are altogether. The sheet can also be adapted to support older students, who need to practise adding multiples of a 10, 100, 1000 etc. The worksheet prints a key (where one picture equals 10 units, say) and then asks the student to represent the sum 50 + 30. The webpage can randomize the worksheet, so you get a different worksheet every time, and it also comes with a design page, so you can tailor the problems to your exact requirements.
