Start by discussing primary and secondary colors and ask students to distinguish between the two. You can also talk about color families and have them practice drawing spirals before starting on their project.
Let’s look at circles today. Do you see anything in this classroom that is a circle? Do you know the different ways circles are measured (circumference, radius, diameter, area)? You can also delve into art history and discuss Kandinsky’s Squares with Concentric Circles.
Ask students to name different kinds of flowers: daisies, roses, sunflowers, tulips, lilies, dandelions, etc. To include a science element into the lesson, discuss with students how insects use flowers.
