#1-10 dot cards with # formation. There are green and red dots on the cards for students to use the finger to make the numbers. I use this one on one with students. . The black dots are big enough for students to place small objects on. I mostly use the flat round rocks used in flower vases. This is also added to the math center with the flat round rocks so students can put the rocks on the dots and count them. For best results print on card stock Then laminate on small laminator.
