Alexandra began by reviewing two and three-dimensional shapes. I explained the difference between 2D and 3D shapes by using simple language and noting 3-D shapes have three dimensions: length, width, and depth, while 2D shapes are flat. She was encouraged to use subject-specific language such as "faces" and "edges." Alexandra used Magna Tiles and Jenga blocks to build shapes and to towers, and we went on a scavenger hunt to find objects around the school that matched the shapes described. This activity helps to facilitate a connection to Alexandra's surroundings and the world around her. Use blocks or other 3D shape manipulatives to have students build towers. These activities help create a dynamic learning environment to help concretize concepts and learning Alexandra has recently acquired. She also completed a 2D and 3D shape sorting activity requiring her to identify and color the 2D shapes blue and the 3D shapes yellow. We got stuck on one and had to research the answer - and by doing so we learned that even when the curved edge of a cone is not drawn in the picture, it's still classified as a 3-D shape. We finished up the session playing a game of Math Bingo and an activity called "Roll a Pumpkin," in which she rolled dice and colored pumpkins showing the correct sums rolled. Alexandra appears to have benefited from exposure and practice using several different activities to reinforce and consolidate her understanding and familiarity with number sense and concepts.
