Geometry
Point of Intersection
Horizontal Line
Vertical Line
When I was eight, I got a geometry kit as a gift, and I’ve loved it ever since!
I’m still learning about geometry, design, and drawing. They all work together, but geometry is the most important one to learn first. It’s been around for a long time, and the best way to learn it is to explore it yourself.
Geometry can seem tricky, but when you build a cube, you really only need to focus on two things: where lines cross and how to make a grid of squares.
Try making six square decimeters and connecting them to make Cubee "D" with cardboard. You will have a lot of fun!

The Square
Look at the yellow side of Cubee “D.” Do you see all those crossing lines? They make up a grid.
When two lines cross at one spot, we call that an intersection. On this grid, the lines go straight up-and-down and side-to-side. Every time they cross, they form a perfect "L" shape, which is a 90-degree angle.
Tip: If you add up the four angles where two lines cross, they make 360 degrees. Remember that number—it’s super important in math!
The lines are all spaced exactly one centimeter apart.
This creates a pattern of small squares. There are 10 squares going across and 10 squares going down. If you multiply them (10 x 10), you get 100 square centimeters.
When you put all 100 small squares together, they form one big shape called a square decimeter.
