I use these in my classroom for our daily calendar work. For the Time page, we use a dry erase marker to practice making times on the analog clock, and writing the digital time. On the Ten Frames page, we use a dry erase marker to color in a "counter" each day (the ten frames go up to 100 days). We also use a dry erase marker to find the days we have been in school on the Find Me! hundred’s chart page, and cross out the day before (up to 100 days). For the Money and Build It sections, we use magnetic coins and magnetic base ten blocks to build the number of the day. Finally, on the Tallies page, we practice making tallies with a dry erase marker for the day in school.
