Marshmallows make everything more fun. We pulled out the marshmallows and toothpicks to explore our shapes and figures.
We talked about the edges, vertices, area and volume. The kids made the basic figures (pyramid, triangular prism, rectangle, square) and then they started building more elaborate figures.
Other activities that we did along this theme:
Guess the Polygon–one person draws a polygon, keeps it hidden, and then tries to describe it for the rest of us to draw, using explanations like, “Draw a line perpendicular to the first line, starting from the right end of the line going up.” We tried using words like perpendicular, parallel, horizontal, vertical, and 90 degree angles.
Diagram the Shapes–We drew a Venn diagram to explain the relationship between quadrilaterals, trapezoid, parallelograms, rectangles, and squares. This was really fun for Bean because she’s always liked coming up with statements like, “All busses are cars but not all cars are busses.” (Not even sure that busses count as a car, but her statements aren’t actually always true and you get the idea.)
Everyday Shapes–we walked around one day finding shapes and figures in our house. The kids took pictures and then I let them draw over them in Photoshop. We had to learn a little about how to draw in Photoshop (I really need to find a class for myself so I can learn everything PSE does), but the kids had fun with this and picked up on the computer stuff really quickly.
