This is a great way to build a sense of community in the beginning of the year and encourage reflection throughout the year.
Use the fall leaves to create a Leaf Pile for each table, giving students a chance to introduce themselves to their classmates and share some fun information about themselves.
Use the winter snowflakes to create a Snow Fall where students reflect on their year so far.
Use the summer trees to create a Classroom Forest where students reflect on their time in your class, how much they've grown (see what I did there?) and look forward to the grade to come.
