In this quadrilaterals and polygons worksheet, students solve the problems using quadrilaterals and other polygons. Students solve six problems.

In this quadrilaterals and other polygons activity, students name various polygons and then decide if each polygon is a quadrilateral. Students also decide is certain polygons regular or irregular.

In this mystery numbers worksheet, students solve 4 different word problems that include guessing numbers described. First, they determine a two digit number that has the sum equal to 6. Then, students determine a two digit number that...

In this geometry worksheet, students examine 14 rectangles of different sizes which are shown with dotted lines. Students trace the rectangles and "colour" in the shapes.

In this mathematics worksheet, students circle the shape in each group that is different. there are six different groups to identify on the sheet.

In this graphing worksheet, students predict how a graph of given functions will work. Next, they check their work using a graphing calculator. Students use algebra to complete the graph of a square and determine transformations.

Students practice calculating the perimeter of different sized rectangles. Individually, they identify the derivations of a function that can show the perimeter and determine how to minimize the perimeter within a fixed area. They use...

Middle schoolers are introduced to the concept of perimeter. As a class, they listen to a lecture describing the derivations of a function that describes perimeter. They calculate the minimum perimeter of a rectangle and determine the...

Students will construct a golden section and a golden rectangle and study their characteristics and connections with the Fibonacci series. They import pictures from the internet and download them into the Sketchpad. Using their "golden"...

Students examine the rhombi or diamond shape and compare it to the square. Students are challenged to create as many flat rhombus shapes as possible and develop a definition for the rhombus shape in 20 minutes while working in teams of...

Fourth graders engage in and explore to develop mathematical, specifically algebraic, ideas. Although the tasks are built around measurement, they are algebraic to the extent that they require 'formulae' to be derived form the geometric...

Second graders explore shapes and create a Silly Shape book. Students recognize that shapes have certain properties and be able to define them. Example, a triangle is any three-sided shape. Students' job is to make a picture on...

Ninth graders explore a variety of geometry and science concept while making an origami frog. The fold paper into the shape of a frog and conduct measurement activities including frog leaps.

Students examine a variety of real life situations in which they must access information, select an appropriate formula, and calculate an answer. A rectangular piece of grass provides an opportunity for the exploration of this lesson.

Students handle geometric shape puppets and answer specific questions about dimension. They write from the shape's point of view comparing themselves to everyday objects.

In this activity, students construct kites and investigate their properties. They also relate the properties to squares and rhombi.

Midpoint Quadrilaterals are quadrilaterals that are formed when consecutive midpoints of a quadrilateral are connected. This activity will use Cabri Jr. to investigate what properties an exterior quadrilateral has if its midpoint...
