Take your class to the farm to learn from agricultural professionals firsthand. Talk with a local farmer to find a facility that specializes in providing educational opportunities for young children. Many family-run businesses assign a knowledgeable member of their staff to host these field trips. Children can ask questions about livestock and crops or simply enjoy a tour. Be sure to enlist adequate parental support for a trip of this nature; it can be difficult to monitor young children outdoors.
Have students make paper bag puppets of their favorite animals. Provide each student with two paper sandwich bags; you may opt to use plain brown bags or splurge for a variety of colors. Use crayon, felt, feathers, buttons and googly eyes to decorate the bags. Host a special story time event featuring these farm critters. Students can participate in the reading by making all of the required animal sounds. This requires them to pay attention to the story and listen closely for a special cue from the reader.
Have students make informational flyers about their favorite farm character. They may choose the farmer, an animal, a plant or a place. Provide each student with a piece of white tag paper. They may use stencils to draw the outline of their favorite thing, paste a picture from a magazine, print a picture from the computer or draw it themselves. Help each child form a sentence about their object -- for example, "My favorite animal is the cow because..."
Draw the outline of a barn on a piece of paper. Cut out the doors of the barn so they swing open. Glue the barn to a sheet of tag paper or recycled cardboard. Have students fill the barn with drawings of the things that are found in a real barn, like cows, horses, farmers, pitchforks or hay. This craft may be modified for other farm structures, such as the silo, farmhouse or chicken coop.
