Start with grid paper and mark the points of the chevron like this:
|Kids can use a ruler, or just a little pre-marked index card like above.|
Once the lines are drawn, the coloring begins! I like the idea of starting with 3 distinct areas to color -- that is 3 different values (light, medium, dark), but you could have students create a greater number of values if you like, but that can be trickier. I think this is a good time to talk to kids about controlling the pressure they put on their pencil (or crayon, if you like that media better).
When the chevrons are colored, cut them out.
Then the fun begins as students arrange the chevrons to make an endless number of designs. I like to share quilting examples at this point for inspiration. The first examples below are using the six primary/secondary colors.
|This one is a bit more intricate, using overlapping chevrons to create smaller triangles.|
|Of course, you can use fewer numbers of chevrons to make quicker designs. This 4-chevron one emphasizes warm and cool colors.|
