Upper graders practice their estimation skills by observing different objects then making their best guess without using measuring instruments. Students are asked to estimate mass, length, volume, and area.

Develop a new measure of the properties of an object. Scholars develop a definition and formula to measure the bumpy-ness of an object. They utilize their formulas to find the property for several spherical objects.

Pupils work on seven problems that use equations and expressions to solve geometry problems. The questions range from finding equivalent expressions to finding areas and volumes of figures. Learners apply their knowledge of angle...

Unlike a volcano, the lesson won't blow up in your face. Young mathematicians use dried beans to discover the relationship between the volumes of cones and cylinders and to write a formula for the volume of a cone. They then research...

Sixth graders investigate the area of polygons. In this geometry lesson, 6th graders calculate area of prisms using geometric formulas. They work with prisms and other rectangular shapes.

In this online math worksheet, students determine the radius, circumference, diameter and area of circles. This excellent resource allows the students to check their answers, and to get "hints" should they run into difficulties. A...

In this geometry activity, 10th graders calculate the area of circle give either the radius or the diameter. The one page interactive activity contains ten questions. Answers and  hints are included. 

Students calculate the area of figures using the formula: length x width = area. They solve area problems using paper squares, geoboards, and real-world problems.

Fifth graders identify the area and perimeter of a rectangle. In this perimeter lesson plan, 5th graders use geoboards and rubber bands to construct various rectangles. Students use the formula to calculate area and perimeter of the...

Students create a scale model to a castle using the dimensions they were given. They calculate the surface areas and volumes of each section of their castle.

Ninth and tenth graders calculate the length, width, height, perimeter, area, volume, surface area, angle measures or sums of angle measures of common geometric figures. They solve problems involving scale drawings, models, maps or...

How high will it bounce? Groups determine the height different balls bounce off of different surfaces. By performing the necessary calculations, they determine the initial and final momentum of the balls. The included worksheet provides...

Students name the area formula and describe how it works. They use area formula to calculate the surface area of various objects. They use the area formula to design a floor plan of an apartment.

For this finding the volume and surface area of rectangular prisms worksheet, students observe the figures with their dimensions in centimeters and apply the formulas to solve. Students solve 3 problems.

Students create identify properties of trapezoids. In this geometry instructional activity, students calculate the area of given trapezoids and review the area formula for parallelograms. They draw a correlation between the area of a...

In this linear and planar geometry worksheet, students use the Pythagorean Theorem, equation of a line, slope of a line and area formulas to solve problems. This three-page worksheet contains seven problems.

Young geometers and biologists investigate the math of nature in an activity that is just the bee's knees. Participants will study the tessellations of hexagons in a beehive, along with the natural rationale behind the specific shape....

Students measure prisms and determine their volume. In this measurement and reasoning lesson, students estimate the volume and area of prisms. They measure given boxes. Students use paper to create prisms and cylinders. They determine...

Scholars make a giant scale model of an object. They will take a regular item and enlarge it to five times its length and width. They attempt this same concepts with a 3D model.

Create a geometric playground. Pupils work through a performance task to demonstrate their ability to use geometric concepts to solve everyday problems. The accompanying engineering design lessons show teachers how the assessment works...

If your pupils think a catalyst is a list of their cats, then this might be the lesson for you! Young chemists study the effect of temperature, catalysts, concentration, and particle size on reaction rates during four different...

Youngsters review different geometric figures and shapes. In this geometry lesson, pupils use formulas to calculate area, perimeter, circumference and volume of geometric shapes. They calculate the surface area also.

Introduce the procedure needed to find the volume of a rectangular prism. Learners rank various prisms such as cereal boxes and tissue boxes from smallest to largest volume. They use an applet to find the volume and surface area of each...

Two students are blindfolded and each receives a cardboard square, one with pompoms glued around the edge and one with pompoms glued all over the surface. They identify what they feel. The class discusses perimeter and area of polygons....
