Comparing 3D Shapes

We used a Venn diagram to compare 3D shapes this week. We organized our shapes according to only stacking, only rolling, and stacking and rolling. We've also discovered that we can construct solid geoblocks by putting together 2 or three smaller 3D shapes.

Geometry and 3D Shapes

 We "hunt" for 3D shapes in Kindergarten Math. By hunting for the shapes, we notice that everything is made of different shapes!

 We also experiment with and categorize 3D shapes when we build with them. There are many questions to be answered!

More Geometry and 2-D Shapes

We created with shapes this week; using cut out representations of shapes the children glued, drew, and combined shapes to create new shapes.

 "Fill the hexagons" is a game wherein the children roll dice and combine different shapes to make a hexagon. There are many colorful ways to make a hexagon!

 We created a "shape mural" with a sky, beach, and water to fill up with shapes. The children created things that they would see at the beach with shapes. There were beach balls made from circles, sand castles made from squares and triangles, and suns and starfish made from hexagons and rhombus.

Geometry

Kindergarten students come to the study of geometry with a great deal of practical experience as they have been seeing and interacting with shapes in their environment all their lives. The Kindergarten geometry unit helps students observe shapes more carefully, focus on the characteristics of different shapes, and begin to describe the similarities and differences they see. The activities that we engage in capitalize on the knowledge of shapes that students bring to the classroom and provide opportunities for them to expand and build on what they already know.

To begin our geometry unit, we looked at various shapes and hunted around the room to find items that were made of that shape- for example, books are shaped like rectangles. We used pattern block shapes to fill in shape outlines, and made a book of shapes which included the sentence "A _______is a ____________until you add___________and then it's a ________________.  The student would cut out a shape, glue it to a page, and add details to complete their shape story. So, for example, "A circle is a circle until you add 2 circles and 4 ovals and then it's a bear."
