Kids like rainbows because of their bright colors. Have the children color a rainbow to help them learn about coloring between the lines. Some children will find this more challenging than others. While they color the rainbows, explain that rainbows form when raindrops scatter sunlight. If you have access to a prism, darken the room lights and shine a light through the prism and project a rainbow on the walls. Teach the kids the names of the colors in the rainbow: red, orange, yellow, green, blue, indigo and violet.
Have the children fold a piece of construction paper in half. Place their hand, palm down, on the center of a second piece of the construction paper. Have them spread their fingers. Give them a pencil and show them how to draw around their hand. Have the kids cut around the outline they drew. Paste the outline of their hand inside the greeting card. Provide them with a circle and a petal cut out of construction paper. Tell them to make more petals and create a flower on the front of the card. While they are making their greeting cards, talk about the colors they are using and the parts of flowers like petals, leaves and stems.
Have the students cut out snowflakes by folding paper in half several times and then cutting around the edges of the paper. When they unfold the paper they will have a unique snowflake. Let the kids make several snowflakes so they can see how each one is different. While they cut out the snowflakes, tell them about the different kinds of weather -- rain, snow, hail and wind.
Make a simple face out of play dough. Give the face a name, like Jerry, to help personalize it, but not the name of a child in the class. Make the mouth out of a long roll of play dough. Place it in a smile and ask the class how Jerry feels. Have the children make their own faces reflect Jerry's face. Give the kids their own play dough and instruct them to make a face. Ask them what emotion their play dough face feels.
