The Color Words Activity Set by iLoveK is a great resource for teaching and reviewing color words!
This set includes 11 colors: red, blue, green, yellow, purple, pink, brown, orange, white, black, and gray. Each worksheet allows the child to color the color word, trace the color word, and use the specific color crayon to color the pictures. There are several pictures on each page, which gives the students an opportunity to practice coloring within the lines.
The directions direct the students to trace the color word with a pencil first, and then to use that specific colored marker to trace over each word again. That offers double the handwriting practice!
