Prime and Composite Animals

    Every week I try and add a creative challenge to the lesson plans to not only add a bit of excitement and motivation; but also give them an opportunity to stretch their imaginations.  
    We have used marshmallows and toothpicks for other games in the past; but I changed it up last week and had the students make prime and composite number animals out of marshmallows and toothpicks.  One animal had to be made from a "prime" number of marshmallows and one animal had to be made from a "composite" number of marshmallows.
    Here are a few pictures of the results.
