They will create their own Op Artwork by using markers, rulers, and geometric shapes. They will also learn about color contrast, and will choose colors that are either high or low contrast. (I might do take a chance to teach about complimentary colors)
Dinosaur week: Fun & Simple dinosaur activity for kids! Maybe for older kids give each shape a numerical value and have them add how much their dino is worth. Can use with class to compare/contrast amounts, etc.
