Have students decorate the mug for someone special for Father's Day, Mother's Day, x-mas, birthday etc.
Project idea: use cotton balls for marshmallows and have student's fill their mug with marshmallows for someone special. Fill the box with a drawing or a photo. Great x-mas presents too!
Project idea: The letter "M" mug, marshmallows, me! Have students work on their letter M.
Project idea: Have older students write a poem with the letter M, mugs or about warm things.
