Using individual photos/leaf shapes from the Fandex field guide, give individual children opportunity to sort them into the following categories: Compare the number and variety of leaf shapes and trees in each location. ![]() Observe leaves at our new building site in the Hort Woods. Use simplified vocabulary to differentiate these shapes-entire=whole, lobed=curved, serrate=pointed, and dentate=teeth-bites.Īdditional Activities to Extend Student Learning For children who can easily sort by these categories, introduce the idea of observing, describing and categorizing leaf edges (margins). Model use of vocabulary from previous activity-needles, flat leaves, simple and compound leaves. See if the children can recognize the attributes discussed in the previous activity and find the trees/leaves on our playground that match the examples from the field guide. Observe leaves on our current playground which has 5 species of trees. This guide is colorful, with individual photos that are die-cut to retain the leaf shapes, and are on cards that may be separated from one another for easy sorting.Īctivity 3. Show children examples of each of these leaf types and shapes, as well as simple and compound leaves, using "Fandex Family Field Guides: North American Trees Identified by Leaf Bark & Seed". Read "The World's Largest Plants: A Book About Trees", emphasizing the ideas listed above. Explain that we can also sort leaves by their shapes in several different ways.Īctivity 2. Have children assist in sorting a basket of familiar materials such as blocks by one or more attributes-such as color, size and shape. (5 minutes)Īsk the children to identify simple shapes. Teaching Model: Hands on learning and student inquiry MethodsĪctivity 1. Use the five senses as tools with which to observe, classify, collect information and describe observations.Group objects according to common properties.PA Learning Standards for Early Childhood - Pre-Kindergarten (2009) ![]() * Fandex Family Field Guide: "Trees Identified by Leaf, Bark & Seed" by Steven M.L. * "Summer Key for Pennsylvania Trees" by Sanford, Smith et. * "The World's Largest Plants A Book About Trees" by Susan Blackaby. * Magnifiers, binoculars, and digital cameras. compound leaf shapes shapes of leaf margins. * Children will sort leaves by a variety of attributes-needles vs. * Children will understand that it is important to observe leaves without picking them because trees need leaves to make food. ![]() * Children will use simple tools to observe leaves that have fallen (with magnifying lenses) and those still growing on trees (using binoculars and digital cameras). * Children will observe leaves from trees growing on our CDL school playground, and at the site of our new facility currently under construction in the Hort Woods. * Trees use their leaves to make food to help them grow. * The edges of leaves also have different shapes. * Leaves can also be described as simple (one whole leaf) or compound (made up of smaller leaflets) in shape. * Leaves that are broad and flat come from trees that lose their leaves in the fall (hard wood trees). * Needle shaped leaves come from trees that have cones (soft wood).
