Blogs are an excellent resource for teachers and parents where they can discover a multitude of math related activities that are easy to implement. Two blogs that are useful for teaching geometry in the early years will be discussed in this post.
This blog features a page (click above image) that chronicles a child’s discovery of a math invitation. A child is invited to use sticks and balls to recreated 3D shapes. Children benefit from having the opportunity to construct and deconstruct various structures, as they are able to see the smaller units and shapes that make up the structure. For example, when constructing a triangular prism, the child begins by creating the sides of the 3D figure, discovering that it consists of two triangles and three squares. This child is also discovering the relationship and similarities between various two and three dimensional shapes. Another page in this blog provides various images of math invitations. The first two images under the header “Building” present more wonderful examples of learning through play. The plastic shapes seen in the first image allow children to view the transformation of 2D structures into 3D structures and the light allows children to see through the shapes. The blocks in the second image are also translucent and colourful so as to engage children and promote geometric learning through play. Here are more examples of block play that promotes the learning of geometry and other math concepts!
This math blog provides age appropriate activities and games for various subjects and is categorized by grade. The blog outlines skills that children learn in each grade and has a corresponding game for each skill. This blog has lessons, such as Learning Shapes with Blocks (click above image), on a range of topics. Children benefit from learning through their senses and the Learning Shapes with Blocks lesson allows them to do so. Touching shapes without looking at them is an important exercise as it allows children to think about what various shapes feel like and encourages them to form a mental image of each shape. Furthermore, it helps children identify the various attributes of each shape, as they touch the sides, faces, and corners of different shapes. The site also has lessons on STEM (science, technology, engineering, and math) subjects. Geometry and spatial reasoning underlie the type of thinking that occurs in the STEM subjects, as well as many others. As is evident in this STEM activity, geometry and STEM are quite interconnected. The children learned about engineering as they built their own globes out of straw triangles. Click here to view the site’s homepage and explore what it has to offer!
