This is a simple page I use with my students to teach them how to read the calendar as well as how to use tally marks, base ten blocks and learn about place value. After modeling for my students a couple of times and then guiding them through it they are now able to do it independently. I place the blank copies at the entrance of our class and right after lunch as they walk in they grab a sheet and begin to work on it while I prep our math lesson. It takes them about five to ten minutes to complete. The great thing about it is that by the time I start to teach place value or base ten blocks my students are already familiar with it. Just in case your wondering it is aligned to common core.
