Third graders use a number of problem solving strategies in this unit of lessons. They determine how to draw and model three-dimensional objects, use co-ordinate systems, determine probability of events, and identify paths of simple...

High schoolers explore the concept of coordinate proofs. In this coordinate proofs lesson, students write coordinate proofs using properties of distance, slope, and midpoint. High schoolers discuss why it is sometimes beneficial to...

Tenth graders recognize, perform and derive rules for basic transformations including translation, reflection and rotation. They also consider compositions, a combination of two or more basic transformations. Students explore both...

In this algebra worksheet, students figure out the equation of the general vector, they find the orthogonal basis and apply the formula to solve the problems.

Students explore the concept of translations. In this translations lesson plan, students discuss similarities and differences between images and pre-images. Students apply translations to coordinates of figures. Students use patty paper...

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.

Students explore the concept of fractal patterns. In this fractal pattern lesson, students use an applet about the Hilbert Curve to answer questions about rectangles and other polygons. Students derive the fractal pattern when dividing...

Seventh graders identify a polygon and classify them using congruent sides and number of edges and vertices. Students transform two dimensional objects into three dimensional objects.

Students, after reading the explanation given below, use FoilSim to determine the weight of the aircraft that can be lifted by a pair of wings of each type. They also design a unique platform of a wing to lift a plane weighing 11500 pounds.

Students locate lines of symmetry in regular polygons and predict the number of lines of symmetry in an octagon. In three different polygons, they construct all lines of symmetry and after making their prediction about the octagon,...

Students use a ruler to determine length and then fit the unit to a scale in miles. This unit will also give a geological awareness of altitude and the difference it makes in travel time. The travel time with Mapquest will obviously be...

In this airplane instructional activity, students complete a crossword puzzle by figuring out the answers to 12 questions about the flying machines created by the Wright Brothers.

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.

Challenge math scholars with polygon word problems that require logical reasoning. They answer two word problems about geometric shapes and their arrangement in a column based on clues given. Next, learners draw a robot made of...

Young scholars identify the latitude and longitude of various locations and calculate the distance between two given coordinate points. They read an eBook, explore the City Zen program, and complete a worksheet.

Students determine an efficient layout of the pattern pieces needed to make a sports bag with given dimensions and specifications. Given a word problem, data set and a diagram, students evaluate the information they have available and...

Learners examine the relationship between circumference and diameter and how to use the formula to find the area of a circle.  In this circle lesson students divide into groups and complete an activity. 

When you engage learners in creating symmetrical objects you are also building their vocabulary and math sense. Kids discuss key words such as, asymmetrical, symmetrical, balance, tint, and shade. They use these elements of design to...

A set of 49 math vocabulary cards ranges from angle to irregular polygon to parallel lines. Each sheet contains two cards: one with the word printed in bold text and the other with the definition.

Where is the line of symmetry in these shapes? Review this concept using the visual guide at the top of the page, explaining how some shapes have multiples lines. Consider demonstrating this concept with large cut-outs, physically...

Explore the relationship between perimeter and area. Learners input the area and perimeter for shapes on the Shape Explorer website, solve problems using geoboards, complete a worksheet, create a PowerPoint presentation, and take an...
