In the first grade, you can use pattern blocks to help students explore the properties of different shapes. Ask them to sort shapes by how many sides or corners they have. Scoop out a handful of shapes and have a student sort them by type. Encourage your students to figure out which shapes fit inside each other. For example, six green triangles can make one pentagon. Allowing your students to explore and experiment with these shapes and how they fit together will help them to learn about the properties of different shapes in a hands-on way.
First grade is a time when children learn to identify a pattern and decide which shapes come next. Use pattern blocks to create and explore a variety of repeating patterns. You can begin with simple alternating patterns and have students determine which shapes come next. After this, move on to more complex patterns and have students create their own patterns. Pair up students and instruct them to take turns beginning and continuing patterns.
You and your students can use pattern blocks to make both pictures and abstract designs. To begin, allow children to choose from several pictures and have them use blocks to fill in their chosen picture. This will help them to see how the blocks fit together. After this, have children create their own pictures and designs or copy one from a picture that they see. As a cooperative activity, have children work together to create a large pattern or picture. Once students have completed their own picture, have them trace around the individual shapes or take a photograph of their design to share with parents.
Your students can play many different games with pattern blocks. For a whole group activity, display a picture or pattern on an overhead for 30 seconds then cover it. Have students use their observation skills to replicate the pattern as closely as they can. After a few minutes, uncover the model picture and allow students to adjust their work to match. The more frequently you do this, the more accurately they should be able to match your pattern. Alternatively, pair up your students and have one student secretly create a pattern, then describe it to his partner. Have the partner try and replicate the pattern based on the description.
