A Different Kind of Mystery Picture [Part 2]

Part One of this article is here.

The next puzzle is going to be based on one of my favorite math concepts, symmetry. If you're a new reader of this blog, my most recent picture book is called Seeing Symmetry (see a video preview here.) Anyway, I wanted to use shapes with and without line symmetry for the clues. The kids find the symmetrical shapes to solve each clue. The squares (on the left) have the lines that will be drawn in the grid square.
The photo below shows the clues page with some of the symmetrical shapes circled in orange. The grid rows and columns are indicated by different symmetrical shapes. By the way, line symmetry is introduced in grade 4 of the Common Core State Standards (4.G.3), and it's also taught in 3rd grade in many states. Just a few of the squares have been drawn in so far (see below).
 Once all the clues have been solved and the lines drawn in, an owl with outstretched wings should appear.
As you can see, the owl is also symmetrical. Any glitches in the drawing will be obvious and the student can double-check that square again. Once it looks correct, they go over the lines with a black or dark marker. I like the Crayola® brand  SuperTips because they are a good thickness, are washable, and don't have that awful brain-melting smell that certain markers do (yes, Sharpie, I'm talking about you.)
One of the nice aspects of this different kind of mystery picture is that once the drawing is complete, each kiddo can color it with their choice of colors.
It'll be fun to see the whole flock of uniquely colored, symmetrical owls that will fly in, don't you think? Here is the cover and a link to this puzzle:
