These are blank charts to fill out. My charts start from 1-20, 1-30, 1-40, 1-50, 1-60, 1-70, 1-80, 1-90, 1-100, 1-110 and 1-120. The students will have a sample at the top in case they do not know their numbers or pattern yet. I hope your students enjoy this as much as mine have over the past years. These go well with a power point I sell. Enjoy!
