Geometry 3rd Grade, Standard #3.1: Understand that shapes in different categories (for example, rhombuses, rectangles, and others) may share attributes (for example, having four sides), and that the shared attributes can define a larger category (for example quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories.
Educational Technology Standard #5: Use technology tools (e.g. Multimedia authorizing, presentation, web tools, digital cameras, scanners) for individual and collaborative writing, communication, and publishing activities to create knowledge products for audiences inside and outside the classroom.
I used Vidcast to teach about Geometry. I focused on quadrilaterals, taught about the four main quadrilaterals and gave examples of them. Vidcast is a great tool to use because you can add your own information, and you can record your voice and teach, and it also has a marker that you can use. I think that it is a fun way for students to learn as well because they aren't just watching a video of a teacher giving them a lecture. A few of the con's that I experienced is that when you add photos, you can't resize them, and if you mess up when recording your voice, you can't go back and fix it unless you want to start the whole video from scratch. But all in all I really enjoyed making a Vidcast video and will be using this in my classroom.
Students, here is a link to the Vidcast I created to teach you about quadrilaterals. Watch this video and familiarize yourself with the names of the quadrilaterals and the terms we use to describe them. We will be going more in depth learning about them this week, and it is important that you know them.
