Supplies you will need:
White acrylic paint
Toothbrushes and paintbrushes
Blue paper
House shapes out of cardstock
Round sponge dauber
White colored pencil
Using shapes cut out of cardstock stick them where you choose with masking tape.
You can just use squares and rectangles and paint the chimneys later.
Create the snow by pulling your finger across the bristles of the toothbrush with white paint on it.
Hold the brush close to the paper and put more splatters of snow where the houses are.
Create the moon in the sky with a sponge dauber.
Remove the taped down houses and add snow to the rooftops and chimney. Add any other details you want like trees etc...
Now add the windows and doors to all the houses using the white pencils.
Great lesson that is pretty much foolproof for any age!
