Sidewalk Art

Today we did a really fun activity we found on pinterest.  The first step was to make an outline of a heart on the sidewalk using tape. You can use painter's tape or masking tape.  The challenge for the kiddos here was, "Can we make a heart out of all straight lines?" Once you have made the outline have the kids fill in the heart with different lines.  This is a great way to look at different shapes.
Polygons are closed shapes with straight sides.
Polygons with:
3 sides=triangle                 6 sides=hexagon              9 sides=nonagon
4 sides=quadrilateral       7 sides=heptagon            10 sides=decagon
5 sides=pentagon             8 sides=octagon

Next we made the sidewalk paint and added food colouring.  This was a great way to remind the kids about the primary colours (red, yellow and blue) and secondary colours (green, violet & orange).

You can have the kids write out the recipe for their recipe book:
Sidewalk Paint:
I cup corn starch
1 cup water
Food colouring

Finally comes the best part....painting.  This entertained the kids independently for half an hour.  It was nice having something they had to work on as a team as well.
