Give each child a large sheet of blank paper, a tub of craft paint and a brush. Place your large sheet of paper on an easel and draw a horizontal line and a vertical line. Tell the children the name for each line, and ask them to copy the lines. Let them practice drawing each line a few times, then start a clean sheet of paper. Draw a line, and ask the children to call out whether it is horizontal or vertical. Continue until you are sure they've learned the names and can associate them with the correct line. Repeat this lesson using a diagonal line and a curved line.
Place a sheet of paper on an easel at the front of the class, and paint circles of red, yellow and blue using thick acrylic paints. Squeeze the primary colors onto a large palette and show the children which colours you need to mix to make orange, green and purple. Give them their paper, brushes and paint palettes with the three primary colors. Call out two colors, and ask the children to call back what color they will mix to make. Let each child make that color. When you are satisfied they have learned the colors, show the children how to make lighter and darker shades by adding white and black paint.
Give children markers and sheets of paper. Place a large sheet of paper on an easel at the front of the class, and draw a triangle. Teach children its name, and ask them to copy it a few times. Using a new sheet of paper each time, repeat this identify and practice process with a square, a rectangle, a diamond, a circle and and an oval. When the children are familiar with all those shapes, start calling out the shapes' names in random order for the children to copy down as quickly as they can.
Place large prints of simple cartoon characters and scenes on an easel. Point to different parts of the pictures and get children to call out the names of the shapes, lines and colors they can see. Keep going with this exploration until the children demonstrate that they have learned that all pictures are created from different shapes, lines and colors.
Place a sheet of blank paper on the easel. Draw a large circle for the head, and ask children to name the shape and copy it onto a sheet of paper. Draw a straight line for the neck, which the children should name and copy. Repeat the name-and-copy process with an oval for the body, rectangles for the arms and legs, triangles for the hands and feet, small circles for the eyes and nose and a curved line for the mouth.
Take your drawing off the easel, and tell the children they are going to make their own person using the shapes you call out to them. Repeat the steps you used when drawing the person, but this time just call out the shapes and their associated body parts for the children to draw, but don't draw them yourself. When the children are finished, give them paints and ask them to color their people in with the color mixes you have taught them.
