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...

Students discover that side measurement is used in determining angle classification of a triangle. By squaring sides, they predict whether triangles be right, obtuse, or acute. They prove the Pythagorean Theorem and use it to solve...

Using the Twist™ application, elementary schoolers design their dream room. They follow the prescribed steps to calculate width, length, perimeter, and surface area in order to create a 2-dimensional representation of their dream room...

Students calculate the length of the classroom using non-standard units of measurement and estimation. Using a cracker box, they discuss measuring various objects in the room as a class, and independently estimate and measure the length...

Students practice estiminating and measuring angles. After watching a short video, they identify angles in objects in the classroom and their homes. In groups, they participate in activities in which they are given a scenerio and are...

Seventh graders measure the diameter, circumference and radius of a circle and find pi using the diameter and circumference. In this geometry lesson, 7th graders work in groups to find the diameter, radius, and circumference of circles....

Students solve problems using various strategies. In this problem solving lesson, students read the book Swimmy by Leo Lionni. Students make fish swimming patterns, measure how many goldfish crackers it takes to make a handprint and...

Students make fudge after reading fractional values in recipes and finding equivalent fractions to those presented in the recipes. They study measurement abbreviations.

In this real numbers worksheet, students perform the given operation with decimals, whole numbers, and fractions. They find the area and perimeter of circles. Students determine the volume of cylinders. This three-page worksheet contains...

Seventh graders determine whether two triangles are congruent and provide an explanation to why they are not. They apply concepts of measurement of angles and collect evidence of congruent angles in the world.

Students complete worksheets involving rotational symmetry. For this geometry lesson, students complete worksheets to identify rotational symmetry and rotations. They compare and contrast rotated figures. Students examine the...

Learners construct the formula for the area of a rectangle.

Students explore tessellations. In this shapes and geometry lesson, students describe the attributes of many of the shapes displayed on an Elmo. Students create examples of tessellations using pattern blocks.

Students construct using Cabri software. In this geometry lesson, students convert between units and apply the correct measurements to build objects. They create the room virtually and manipulate the shapes to the desired measurements.

Young scholars calculate the length, width, height, perimeter, area, volume, surface area, angle measures or sums of angle measures of common geometric figures. They create an equation of a line of best fit from a set of ordered...

Students decide what body measurements they need to make garments such as a pair of pants. They make a list, and work with a partner to take and record those measurements in centimeters. They discuss the use of centimeters.

Students solve the area for parallelograms,squares, rectangles, trapezoids, and triangles. In this geometry lesson, students compare and contrast two dimensional shapes and apply their properties to solving real life scenarios. This is a...

Third graders estimate and measure the length of a whole color-segmented, candy gummy worm. Then, as students bite off each segment, they estimate, measure and record findings in an activity log.

Pupils use fractals to analyze nature. In this geometry lesson, students work in groups using technology and math to communicate. They identify where in the real world fractal can be seen.

Students discuss how big is big. They compare the area and perimeter of an acre and a football field.

Upper graders represent multiplication of a two-digit number by a two-digit number as the area of a rectangle with dimensions of the two factors. They find patterns for the number of different base ten blocks in a rectangle representing...

Middle schoolers redesign their school to make it more energy efficient, and create a model of their design. Learners get together in groups of 5, and they take on the task of making their school more energy efficient. To do this, they...

Students are given the task of designing an apartment. In groups, they practice estimating the area and perimeter of different shapes. After designing their space, they apply the same formulas to solving real-world story problems.

Seventh graders examine the process of constructing a site plan map at archaeological sites. They discuss the process of mapping techniques and calculation of percentages, create a plan site map of a cellar at Jamestown, and calculate...
