# 2D and 3D Shapes

I didn’t spend too much time on geometric shapes for grade 1. My daughter grasped the concept fairly quickly while she was still in first grade. However, I still think geometry for kids is a very important part of the math curriculum.   In first grade, she learned two-dimensional shapes like a circle, triangle, square, and rectangle.  Actually, her class also included pentagon, hexagon, and octagon.  She also learned 3 dimensional shapes like spheres, cylinders, cones, cubes, rectangular prisms, and pyramids.

At this age, the most important thing to know about geometric shapes for grade 1, is where they are in their everyday lives.  It’s much easier to teach about circles by showing things that are circles or showing things that are rectangles.  It’s even better still if all of the association is in the form of a song.  This is probably their best chance of remembering the names of the shapes.

## Two Dimensional Shapes

I created a little song that is loosely based on a pre-school rhyme that teaches the finger family. I got the idea for this song from the TeacherTipsters.com.

Circle, Circle
Circle, Circle
What are you?
I am round like a cookie and a pizza too.

Triangle
Triangle
What are you?
I have three sides like a caution sign.

Square, Square
Square, Square
What are you?
I have 4 equal sides like a checker board.

Rectangle
Rectangle
What are you?
I have 4 sides like my favorite book.

## Three Dimensional Shapes

Teacher Tipster has a rhyme for 3D shapes. If follows the pre-school rhyme for the finger family. It also does a nice job of connecting real world objects with new mathematical terms. My daughter already knew her shapes and did not seem to need this review. However, she loves songs, and she sung right along with me when I introduced the printables to her. If I had needed to enhance her learning of this terms, I would have also brought out the real world objects so that she could touch them and play with them.
