Presenting ... the gold standard for a lesson. Learners first investigate a task maximizing the area of a plot for gold prospecting. They then examine a set of sample student responses to evaluate their strengths and weaknesses.

How many different types of triangles can your class name? A discovery lesson guides learners through an exploration of the different triangle types and the relationships between their angles and sides. Using coordinate geometry,...

Students discover the value of Pi.  For this value of Pi lesson, students measure the circumference and diameter of various circles on their graphing calculator.  Students find the ratio of the circumference to the diameter and...

Graphing paper, pencil, ruler, protractor, and compass, all get replaced or supplemented with this dynamic geometry application. Here, you can create, move, and scale many different shapes, as well as, explore and change their properties...

Don't let your classes get stuck on area calculations—grab their attention with an inquiry-based lesson! Scholars must develop a plan to determine how may sticky notes it takes to cover the surface of a door. They decide on the...

Design and build a rover ... then eat it? This activity has groups of two design and build Mars rovers. The teams determine what instruments they want to include with their rover and plan a budget. They calculate the cost of the body of...

Introduce your math class to the perimeter of a circle. Teach them that pi describes the relationship between the circumference and the diameter. As a hands-on investigation, pairs or small groups use string to compare these two values...

Students, after reviewing the measuring of the lengths of sides of different shapes along with the calculation of their perimeters and areas, encounter what it means by the 'perimeter' of a polygon. They practice measuring units of...

In this drawing plans to scale worksheet, students examine how to convert small scale drawings to real life plans. They work with perimeters and areas when given the scale ratio. They complete 7 multi-step questions. They enter the...

Students find the factor of proportionality in similar polygons. In this similarity of polygons lesson plan, students measure the sides and angles of polygons and derive a factor of proportionality between corresponding pairs of sides...

For this math worksheet, young scholars will work with a coach to find the total area of a tree-house. Students will follow a step-by-step process and notes are provided for the coach.

Students measure the perimeter and area of their polygons. In this geometry lesson plan, students calculate the volume and area using the correct tools. They calculate the time and temperature and the perimeter and side lengths of...

Second graders distinguish between and use nonstandard and standard units of measurement, use appropriate tools and techniques to measure length and width, and record and interpret data using graphs.

In this geometric figures worksheet, 10th graders solve and complete 18 different types of problems that include various figures. First, they find the area of the figures shown if consecutive sides are perpendicular. Then, students find...

Students create a ruler for the purpose of measurement using the standard and metric systems. The rulers are of different lengths and are compared to one another. Then students make conversions of different lengths using both systems of...

Eighth graders measure in feet and inches and convert to explore the relationship between the converted measurements. In this measurement lesson, 8th graders use the whisker and box plot to represent the measurement of a cat. ...

Students determine length, width, perimeter, and surface area, and work with two-dimensional representations of three-dimension objects to design and write descriptions of their dream bedrooms.

Second graders participate in a series of hands-on, online and multimedia activities that examine the concept of area. They view clips from the animated series Math Monsters and discuss the purpose of area and how it is used in the real...
