This is a whole group or partner number sort. Students will decide if a card is a way to represent a certain number, or is not a way to represent that number.
There are 6 ways to represent each number (including tens frames, dominoes, the number word, the numeral, tally marks, and a picture), and 6 incorrect ways for each number.
Each number set is color coded so the pieces do not get mixed up. Numbers 11-20 are included.
