Grade 3 Rotational Symmetry

Third graders included math integration during this lesson on ROTATIONAL SYMMETRY. When something can be rotated and still looks the same it has rotational symmetry. Some things we see around us that have this property are snowflakes, ferris wheels, flowers, and starfish.

 

The students used their name or initials to use as a design to repeat four times. It took a lot of precision and patience to transfer the design in pencil, then trace in sharpie, and finally color with COMPLEMENTARY COLORS. Colors that are complementary are opposites on the color wheel.

 Red and green, shown here, are complementary colors.

Here are some of the amazing examples that were on display for over a month in the hallways of school!

Some lessons have been taught to multiple grade levels. Not all schools participate in the same lessons due to budget, materials, student needs, etc. Please leave a comment with praise, questions, or ways to polish.
