Included in this file are the numbers 1 - 200 in 11 different colors. The cards are formatted to a 2" x 2" size. This will fit most 100 charts. Cards can be used so that each line of ten in the chart is a different color or build your growing class number line using the cards. When building a number line, each month will be a different color allowing you to see how many days the students have been in school each month as well as helping students identify numbers by saying something like, "The number 10 is yellow...or can you name a number that is on a blue card".
