Qui a perdu une dent? is a way of tracking how many teeth your students lose throughout the year. This sheet could be posted beside your calendar and added to your morning calendar routine (in a Primary classroom). Each morning you could ask “Qui a perdu une dent?”. If a student has lost a tooth you can colour in a square. There is a section to track for boys and for girls. You can print off more than one sheet as needed and attach them together lengthwise. As the year progresses you can begin to incorporate math such as counting by ones, twos or by tens. This could also be a way of introducing bar graphs and discussing more than/less than.
