This is a 34 page Smartboard file teaching Geometric Series. The lesson starts with definitions and formulas. Students learn to find the sum of a series. For example find the sum of the first 8 numbers. They can see the first few numbers. From there they have to come up with the common ratio.
Geometric Series Project "The Sierpinski Triangle"
This is a mini-project where students apply the finite and infinite geometric series formulas and create the Sierpinski Triangle. At Christmas time we create Sierpinski Triangle Christmas Trees which are great to decorate the classroom.
