These math posters are a great way to add a little warmup/review to your daily calendar time/opening/circle time/morning math to enhance number sense and processes of your students with daily practice. Four different posters are included and can all be used at different times of the year or for different purposes. Skills included: ten frames, counting, numeral writing, number collection boxes, addition/subtraction, number patterns, tally marks, coins, and more!!! We like to "share the pen" and take turns completing them each morning. They also work well for center practice. Laminate and use with dry erase markers or create overheads from them!
