Buffon's Needle (Activity)
Experiment with a simulation to get an approximation of Pi by dropping a needle on a lined sheet of paper.
Looks at the history of tessellations, why they are important and examines some patterns in nature and art.
Shape Explorer (Discussion)
Introduces students to finding areas and perimeters of irregular shapes on a grid.
Factorize 2 (Activity)
Visualize factors through building rectangular areas on a grid. As you draw each factor set on the grid, the factors will be listed. Factorize 2 is one of the Interactivate assessment explorers.
This worksheet is for use with the Ideas for Working with Fractions lesson plan (http://www.shodor.org/interactivate/lessons/WorkWithFractions/).
Shape Explorer (Activity)
Learn the relationship between perimeter and area. A random shape will be automatically generated. Calculate the area and perimeter of this shape. Shape Explorer is one of the Interactivate assessment explorers.
This worksheet is for use with the Factorize activity (http://www.shodor.org/interactivate/activities/Factorize/).
Discusses the relationship between geometry and probability.
Students learn to identify a variety of patterns using sequences and tessellations.
