This activity is for children 3-6 who are learning what it means to estimate and take an educated guess.
1. Build a 3D shape (box, triangle, etc)
2. Pin the cloth around the shape, so that balloons can fit into the shape.
2. Blow up balloons in various sizes.
3. Have the children guess how many balloons they can fit into the shape. Talk about the...

Intersecting lines are lines that cross each other. Please illustrate intersecting lines.
This is is great.
It looks like you understand the concept, but we are working in three dimensions right now. Technically, those lines are on different planes and may not intersect.
We are not going to get into planes right now, but we will learn more about...

Build me a line
.
What is a line? Answer a line goes on forever in two directions.
We are going to use the yellow balls at the end to show an end to a line. Now build me a line.
What is a segment? A segment is a part of a line with two ends. Please build a segment.
What do you think a ray is? Please build a ray.
Practice...

You will need paper, pencil, and your notes or a resource such as your iPad.
Option 1: Please write a short essay explaining how geometry plays a roll in engineering and design. Explain how geometry can assist us in building stable structures.
Option 2: Discuss angles and describe whether angles would have the same impact on building and...

There are many many different types of polygons. Today we are going to work with many types of flat polygons. We are going to start out with building a triangle. I would like for you to build one triangle for me. In two previous lessons we already learned something about the triangle we have already built today. (See geometry-triangles and geometry-right...

Build a polygon and ask:
What type of polygon is it?
How many dimensions does it have?
Can we make it have volume?
How can we create volume?
What is volume?
Spend your time making three-dimensional polygons. Pay attention to the obstacles that you find has your building.
If you were a toy engineer what things would you consider...

We know we can absolutely make right triangles. Why do we know we can definitely make a right triangle?
The two forms of right triangles are isosceles right triangles and scalene right triangles. An isosceles right triangle has a right triangle into equal length sides. A scalene right triangle has one right angle and no same length sides.
Please...

In this triangles lesson, we’ll discuss the three different types of triangles. There are equilateral triangles, isosceles triangles, and right triangles.
Do you know what it is to be an isosceles, right, and equilateral triangle?
Your challenge is to build one isosceles triangle, one right triangle, and one equilateral triangle.
Your child should...

After learning all about polygons, polyhedrons and Sierpinski Triangles, we can move onto a new fun shape: PolyYurts!
Start with a polygon shape as the base (help as needed – great time to talk about what makes it a polygon!), and let the kids problem-solve how to build up from there.
For example, a HexaYurt would start with a hexagon as the...

Step 1: Depending on the level and interest, start with simple figures like a triangle, square, or pentagon, then move to a hexagon, heptagon, octagon, nonagon, decagon. Using the shorter rods may be easier as the polygons get more complex. Discuss what makes a polygon and what changes happen as they increase in complexity.
Here are some fun facts:
A...

This geometry activity is great because it can be used for various ages. This activity is great for counting, construction and geometry.
Objective:
Build and identify shapes
For a cube you’ll need:
8 spools and
12 green rods
Start by building 2 squares, the...
