Learners investigate the concept of how earthquakes occur and the after effects of how they effect landforms. They conduct research it using a variety of resources and measure the varying intensities of how earthquakes effect the...

Second graders explore geometric shapes. In this lesson about geometry, 2nd graders create their own vest using geometric shapes. Students work with a partner and fit their partner for the vest they design. Students understand geometric...

Seventh graders recognize the characteristics of isosceles triangles. In this isosceles triangle lesson, 7th graders use geoboards to create isosceles triangles. Students record results and explain why they have an isosceles triangle.

Just what does it take to show two rhombuses are similar? The assessment task asks pupils to develop an argument to show that given quadrilaterals are rhombuses. Class members also use their knowledge of similar triangles to show two...

Using their knowledge of right triangles, pupils find out how far a ship is from a light house. Class members determine how far around the world a ship would be sailing at a constant speed.

During this hands-on activity, young chemists build molecular models based on the Lewis dot structure before studying valence shell electron pair repulsion theory. 

Experiment with optical resolution using an inquiry-based lesson plan. Young researchers calculate fellow classmates' optical resolutions. They apply the information to understand the inner workings of optical instruments.

In this geometry worksheet, 10th graders measure different nets to figure out the shape they represent. They enlarge the nets, cut them out and create the shape to get their final answer. There are 10 nets with an answer key.

In this geometry worksheet, students use the correct units to measure distance, length, diameter and height. There are 8 questions with an answer key.

Young mathematicians identify different cases of intersecting secant lines. They then investigate the case where secant lines meet inside a circle.

Sew up your unit on operations with decimals using this assessment task. Young mathematicians use given rules to determine the amount of fabric they need to sew a pair of pants. They must also fill in a partially complete bill for...

Emergine space engineers discover the area of complex geometric shapes. They find that, just as a spacecraft is composed of many smaller parts, so can polygons be broken into smaller shapes.

Students study about our dependence on the earth's resources for materials. They practice their knowledge of geometric shapes by recognizing them in the context of the story.

There are many different ways to show a proof of the Pythagorean Theorem.  Here is a nice hands-on paper cutting activity that shows a graphic representation. You can even challenge your young Pythagoreans to come up with their own...

For this counting to ten worksheet, learners solve four problems in which objects in a set are counted. Students then draw more objects to make ten in all. Learners then write the number 10.

In this beginning fractions worksheet, students solve four problems in which the same geometric figure is divided in half two different ways.

Learners explore geometric concepts using technology. They manipulate the TI to find important math topics. This activity requires a TI-84 or higher.

Students explore the idea of having Benchmarks to estimate the length of given objects. Students demonstrate acquired knowledge of the basic units of length by making reasonable estimates. Students create a personal benchmark.

In this perimeter worksheet, students calculate the perimeter of rectangles.  This one-page worksheet contains 6 perimeter problems.

In this integers worksheet, students solve 16 addition problems by adding two integers together. There is no answer...

Young scholars determine the distance between two points.  In this distance formula lesson, groups of students determine the distance between points in real life situations.  They calculate the distance from one point in...

Learning how to define vocabulary words related to solving parallelograms will assist your learners in identifying different parallelograms. They use the navigator to view different shapes created by moving the parallelogram around.

In the second of two similar worksheets, anglers compute missing angles when given an alternate, supplementary, or complementary value. There are six problems to solve, but each of them requires two to four solutions. This is a nice...

In the first of two similar worksheets, geometers compute two to four unknown angles when given an alternate, supplementary, or complementary value. There are six multliple-step problems to solve. This is a nice challenge for your...
