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.

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 conduct their personal investigations into paper airplane flight. Cooperative teams are formed, with students choosing the paper airplane design that they are most interested in building.

Students make fudge after reading fractional values in recipes and finding equivalent fractions to those presented in the recipes. They study measurement abbreviations.

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,...

In addition to the catchy title, this lesson plan provides upper graders an opportunity to more closely scrutinize the attributes of plane figures. In particular, they focus on the similarity of different shapes. Both whole-class and...

Learners identify the stages of the water cycle. They listen to the book "Magic School Bus: Wet All Over," examine the Build Your Own Water Cycle website, predict and measure the amount of water in a jar for a week, and read a short play...

Estimate the value of one of the most famous irrational numbers. The hands-on instructional activity instructs classmates to measure the circumference and diameters of circles using yarn. The ratio of these quantities defines pi.

Middle schoolers discover the relationship between the circumference of a circle and its diameter. They find the length of an arc of a circle.Students use estimation strategies in real-world applications to predict results (i.e.,...

Elevate your fifth graders' understanding of math concepts with a series of vocabulary posters. Featuring terms concerning probability and statistics, measurement, algebra, and decimal place value (and many more), the posters are...

Begin seeing the world through the lens of geometry! Use the 19th installment in a 25-part module to apply the Pythagorean Theorem to solve real-world problems. Individuals sketch situations resulting in right triangles such as the...

Fourth graders swap local soil samples with another school and examine the differences. They research soil properties, identify organisms that live in soil, create and maintain a biome of soil decomposition and design a poster to present...

Students receive a copy of a "Spaghetti Measure" task sheet along with the scoring rubric. Students preview the task and the rubric prior to starting the task. tudeThey determine the circumference of a circle of spaghetti that will...

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...

Young scholars estimate and accurately measure the size of angles communicate with the appropriate geometric terms and symbols to describe and name angles, lines, line segments, rays

Second graders investigate rice or gohan as it's called in Japan in a couple of experiments. They tally the results.

Fifth graders create a reflection of a poygon using a Mira. They discover that a line connecting a vertiex of a polygon and the corresponding vertex of its reflection is perpendicular to the line of reflection. Students create a glide...

Students view a demonstration that simulates cloud formation. They read a poem about clouds, participate in a class demonstration using warm water and ice and write a paragraph summarizing their observations.

Students discuss situations when it is useful to know exact weight of object as opposed to estimated weight, estimate weight of various items, weigh them on scale using ounces and pounds, and compare their weights on Guess Your Best...

Pupils identify he proportion of a cereal box. In this algebra lesson, students define the relationship between patterns, functions and relations. They model their understanding using the cereal box.

Students use the Internet to answer lab questions about fractals, and then construct fractals using the initial stage and iteration rule. They complete tables and generate rules for the "nth" term and create their own fractals.

Second graders publish a class cookbook of their own recipes. They explore the nutritional value of foods, calculate the measurements, and prepare a healthy recipe for the class.

Fourth graders determine the value of ? by measuring the circumference and diameter of circular objects such as soup cans, Oreo cookies, etc..
