Here is an activity that works great to encourage graphing skills around the winter holidays.
Mix together the Santa Mix
-Snowflakes (chex mix)
-Santa's Beard (marshmallow)
-Christmas Tree Bough (pretzel)
-Snowman Button's (raisins)
Pass out a small snack bag to each student and allow the students to graph their top ingredients. Be sure to check for labeling of axis and accuracy.
Then have students discuss their results and compare. Answer the questions for verification of understanding.
