Each workbook offered by Dot-t-Dot Math Worksheets has 36 pages. One book is for addition and subtraction, and one for multiplication and division. Students do 4 or 5 problems on each page. They do a problem, follow the dots for that problem, and see their lines make a letter. The letters make a word. At the top of each page art work suggests what the word might be. First guesses are not always right. It's fun! The worksheets are sequential and self-correcting.
