Discovering the Area of a Circle Activity
I give each student one half sheet with the instructions and 2 circles. The instructions advise the students to cut out the left circle into 8 sectors and shape their sectors into a parallelogram. Before the next step, we discuss as a class what the formula is for finding the area of a parallelogram and how we can use that to derive the formula for the area of a circle. My 7th graders usually spend about 20 minutes on this activity. They will need prior knowledge of the circumference formulas an

Scale Factor Perimeter Area Investigation
I no longer feel comfortable selling this resource. Teaching evolves and there's a better activity out there. Please check out Desmos Classroom. This is currently the activity that I created that I'm most proud of. My students get it after they have interacted with the shapes on screen. No more cutting and making envelopes.I'll leave this product up but available as a free resource. Please let me know in the comments what you think.---------This investigation helps students understand the relati

Our World of Circles: An Inquiry-Based Lab for Pi
In this activity, students "discover" what pi represents by measuring various circumferences and diameters of circular objects and identifying the pattern. This aims to provide deeper conceptual understanding of pi, and therefore assist students in understanding pi's many applications.

Measurement Lab: How Long Is It?
This is an outline of a lab used in a middle school math class.
Students work in groups to measure various items around the classroom and convert measurements both within customary and metric measures. Students then reflect upon their findings.

Proof of the Pythagorean Theorem
This is a hands on geometric proof of the Pythagorean Theorem. Students arrange four congruent right triangles two different ways on a large square to show that the sum of the areas of the squares formed by the legs equals the area of the square formed by the hypotenuse. The only required materials besides the handout are scissors for each student or team. Rulers are not required because the template already includes unit markings.

Quadrilaterals Possible or Impossible
Students will use the properties of quadrilaterals to decide if a figure with the given characteristics is possible or impossible to create. If it is possible, than they can use Geometer's Sketchpad or other software to create it.

Area with index cards
Have you ever wondered where the area formulas for triangles, trapezoids and parallelograms came from? In this activity, I walk you through how to derive these formulas using index cards. The activity is designed to build strong, conceptual understandings while creating a hands-on product that they can keep in their notebooks for years to come!

Polygon Angle Sum Lab
This lab has students apply their knowledge of the Triangle Angle Sum Theorem to derive the sum of the measures of the interior angles of a polygon (the Polygon Angle Sum Theorem). As opposed to having students memorize a formula, the lab approach requires students to be creative and synthesize multiple mathematical ideas from geometry and algebra.Pre-planning:30-60 minutesdecide how students will get into pairsPrerequisite Knowledge:the triangle angle sum theoremarithmetic sequencesmodelling u

8th grade Task Rotation for Fractions and Volume
This is a task rotation for my intro chapter to 8th grade math. I do a combination of fractions and geometry formulas. Give each station roughly 10 minutes to work on each problem. For station 3 it might help to pre tape the two cylinders to cut down on that time for students and to give them more time to work.
