In this consumer mathematics activity, students explore a variety of topics in mathematics including simple interest, perimeter, area, volume, translating words into symbols, percentage problems and mortgage calculations. The fourteen...

Seventh graders review the process of finding the area of a rectangle and complete a couple of examples as a class. They discuss what a parallelogram is and what the formula would be for finding its area. They listen to an explanation...

Young scholars create and give oral proposals for the construction of a gazebo using a blueprint created with Geometer's Sketchpad. They then build a gazebo model using the blueprints created and provide evidence why it should be...

Junior geometers discover that polygons can be decomposed into triangles and that the number of triangles can be determined by a rule. Note that the Geometer’s Sketchpad® software is required to carry out all components of this...

Students examine a math worksheet and determine how to divide a single triangle into four of equal area. Using geometric principles, they sketch two additional ways to divide into into four equal triangles. To conclude, students...

Students work together to make figures out of tangram squares. In groups, they calculate the measurements they need and apply the Pythagorean Theorem. They complete a worksheet solving equations using the theorem and review their answers.

Middle schoolers construct a basic cylinder out of a piece of paper, then answer seven questions about their cylinder. Questions have to do with measurement, volume, radius, etc.

Math wizards learn the five-step plan to solve math word problems. They investigate the five-step process for solving word problems, and examine the use of code words for each of the operations and solve a problem using the strategies.

Fifth graders estimate perimeter, area, and volume. They measure perimeter and area using nonstandard units of measurement. Students add and subtract non-standard units of measurement. They add mixed numbers and simplify the sum.

Fourth graders work in a group of 4 to make rectangle with a 12m length of string. They discuss its perimeter and how they would calculate its area. Then another group of 4 make another rectangle and estimate if the area would be greater...

Students graph lines in a coordinate plane. In this geometry lesson, students graph lines on a coordinate plane, and identify the slope. They calculate the volume, area and perimeters of the shapes created on a coordinate plane.

Students identify the ratios of different triangles. In this geometry lesson plan, students identify the similarity and differences of triangles. They use the navigator to move the sides of the triangle around.

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.

Second graders explore how to incorporate a new type of technology, the cash register and/or a calculator, as a motivational tool for solving real life problems. They practice estimating money and counting back change from $20.00.

Students explore angles and their use in Geometry. Students investigate three different kinds of angles: obtuse, acute, and right angles through an online activity. They identify pairs of angles with special relationships: vertical,...

Fifth graders build models. In this measurement lesson, 5th graders build paper models to represent square centimeters, square inches, square feet, cubic centimeters, cubic inches, cubic feet, and perimeter.

Second graders measure surface area and perimeter using estimation. They complete a variety of measurement activities using Cheerios breakfast cereal.

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.

Third graders use nonstandard concrete methods to estimate and record measurements of their body.

Fifth graders use Geoboards to demonstrate how shapes can be made by looping the rubber bands over the nails. They make a triangle on their Geoboards. At least one side of the triangle should be either horizontal or vertical. The picture...

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...

In this care homework worksheet, students add, subtract, multiply and divide integers.  They multiply and divide fractions.  Students complete percent problems and determine the area of polygons.  This three-page...

 In this Integrated Algebra worksheet, students solve problems that reflect the topics covered during the course of work.  The answer key identifies each question by standard and topic.  The twenty-four page worksheet...

Students construct and maintain a school garden. In this gardening lesson, students plan the construction of the garden by writing letters to local businesses asking for supplies and materials; students build the garden using their math...
