These Ten Frame Numbers 0-20 Cards are 6 inches X 6 inches and were designed to be displayed in a straight line to fit in a 12 foot long space above a dry erase board. They can be "stacked: in rows to fit smaller areas. There are 3 sets-one in a Traditional Handwriting font, one with Modern Manuscript Handwriting Font and one that is Editable so that you can choose the style and size of the font. The colors are in assorted primary colors- red, blue, green. yellow, orange and purple. They coordinate with my Alphabet card set in Primary Colors. Look for a word wall set soon! Please look at the Preview to see a photograph this set in Brights. You will need Powerpoint to edit the Math Cards.
