Artists use one triangle and chalk to create a five-pointed star. This is good for talk about, not only how you go about positioning the triangle five times to create the star, but also for the starting point of the chalk marks (on the triangle, brushing out) and conversation about the direction you "swipe" the chalk (from the triangle straight out as you work your way around the point of the triangle). It is a good idea to practice this on newspaper first! If you think the triangle method is too hard for you group, this can be done with a full star pattern instead.
After making the initial chalk mark, students swipe the mark again with their finger, smearing the chalk outward, so the star looks like it is shining.
Once the stars are done (I like the kids to make various sizes using small and large triangles), it is time for some stripes.
These were done by dipping the edge of a piece of cardboard (we use scraps of illustration board) in tempera (acrylic works, too) and "printing the stripes". I emphasize, "straight down, straight up" to avoid sideways smears!!
You can decide whether to have your kids stick with vertical/horizontal stripes like the one above, or let them print however they like, as in the example below.
The motivation for all of this was our local National Veteran's Cemetery (seen across the street from the Federal Building), which is adorned right now with thousands of American flags at the gravesites and along the inner roads. I love driving by this time of year. Hope you all have a meaningful holiday as summer nears!
