During calendar time we record one tally mark for each day we've been at school on a monthly tally. At the end of each month we add up the tally marks and record the total number of days we were at school. We also have a tooth chart. When someone loses a tooth, they print their name on sticky note and put it on our tooth chart. At the end of the month we save the names as a record of how many teeth were lost that particular month. This week, we pulled out the monthly tallies from the year and recorded the data on a graph.
