Fifth graders apply the symmetry and angle properties of polygons and use fractions to express the relationships between the areas of rectangles, squares, and triangles. They analyze various country flags and develop mathematical...

Young scholars are asked to describe to a partner how he or she walks to school or the bus stop. They are shown on the overhead an one-inch grid paper, and at the intersection of two lines on the grid paper, students are shown a house...

Fourth graders identify and classify different triangles and quadrilaterals. Then they demonstrate an understanding of plane and solid geometric objects and use this knowledge to show relationships and solve specific problems. Students...

Tenth graders investigate the theorems of angles and lines to prove triagle sum theorem. In this geometry lesson plan, 10th graders discuss the theorems of triangles and how it is used to solve for missing sides or angles. They review...

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...

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. 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.

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.

In this counting to ten worksheet, students solve four problems in which objects in a set are counted. Kids then draw more objects to make ten in all. Students 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.

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.

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...

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

Students use triangulation method to locate meteorite landing site on the map. In this earth science lesson, students participate in a meteorite treasure hunt set up by the teacher. They explain how this method is used by scientists to...

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...

In this perimeter learning exercise, learners calculate the perimeter of rectangles.  This one-page learning exercise contains 6 perimeter problems.

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.

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

Students 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 the...

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...
