This is a Smartboard activity that allows students to practice working with tens and ones. All the numbers in this activity are 10 - 19. Each page has a full ten frame and a certain amount of dots left over. Students need to fill in on the lines provided the correct number of tens and ones. They will then add them to get the correct number (1 tens + 3 ones = 13). The preview file has thumbnail shots of many of the pages from this file.
