In this interactive activity, students review attributes of equilateral polygons. They are introduced to the concept of a tessellation. Using protractors and pre-cut shapes, students arrange a variety of tiles to create tessellations....

Students explore the concept of perimeter. In this perimeter lesson plan, students discuss how to find perimeter of various shapes. Students use the Perimeter Explorer applet to find the perimeter of various shapes.

Students examine the concept of standard deviation, calculating mean, and collecting data. They measure the standard deviation in a bag of M&M candy, record the data, and calculate the mean.

Students determine mean, median, and mode. In this problem solving lesson, students evaluate a set of data to determine the mean, median, and mode. Students work in small groups practicing cooperative learning skills as they problem solve.

Sixth and seventh graders construct a "metric machine" as a kinesthetic aide in converting from one unit to another in grams, liters, or meters. They complete a metric activity on the Internet and view about five minutes of a video on...

Students study the egg code to learn about sea ice. In this sea ice lesson, students discuss and view a diagram to learn about the egg code when describing sea ice and its thickness. Students work in groups to play a game using the egg...

Young scholars collect data on a robot and relate the behavior to prove there is an infinite minute set of numbers. In this algebra lesson plan, students verify that there is always a number between two numbers. They analyze and...

Students demonstrate proper scientific observation skills. For this investigative science lesson, students make observations, record their findings and form conclusions in order to improve their scientific documentation and writing skills.

Students study fractions by comparing rations using Cuisenaire rods. They make predictions, measure lengths using Cuisenaire rods and explain their answers. Next, they discuss the relationship of the different rods in terms of their...

Young scholars explore the concept of the golden ratio in nature and architectural design. They discuss examples such as petals on a sunflower and the Parthenon. In small groups they take turns measuring their body parts to find a...

Students find the area of polygons.  In this area of polygons lesson, students find the area of parallelograms, rectangles, squares, and other polygons.  They identify each given figure and determine the appropriate formula...

Students discuss the importance of scaling drawings. In this math lesson plan, students create a scaled drawing of circuit boards. They explain why accuracy is very important when scaling.

Young mathematicians define population, draw convenience sample from the population, draw quota sample from the population, and draw random probability sample from the population. They explain why a random probability sample usually...

Young geometers investigate and apply properties of quadrilaterals.  After a review and discussion of key terms, learners use a computer applet to explore four-sided figures and classify them according to their attributes. The...

In this globe learning exercise, students learn how longitude is measured on a globe. Students read the information before answering 5 questions. A globe will be required.

Students investigate modular arithmetic and how to use it to solve real world problems. In this modular arithmetic lesson, students use computers to work on modular arithmetic after a teacher guided lesson. They complete guided practice...

Students explore Newton's laws using CEENBoTs. In this physics lesson plan, students collect data and create tables and graphs. They calculate speed, acceleration and forces using mathematical formulas.

Young scholars compute and estimate using mental mathematics, paper-and-pencil methods, calculators, and computers. They measure and compare quantities using appropriate units, instruments and methods. They utilize worksheets imbedded in...

Sixth graders measure and investigate the densities of several objects. They, in teams, determine the mass and volume of each of the 5 objects and record the measurements in the data table.

Students calculate angle measure for triangles and complementary/supplementary angles. After a lecture/demo, students utilize a worksheet imbedded in this plan to gain practice.

Evaluate young mathematicians' understanding of area and perimeter with this series of three assessment tasks. Challenging students to not only calculate the area and perimeter of irregular shapes, but to explain in writing their...

Students explore geometry by participating in a class card game. In this triangle lesson, students utilize playing cards with shapes on them which they group up and discard, similar to "Old Maid." Students complete a worksheet and answer...

Students identify integers as rational and irrational numbers. For this algebra lesson, students measure and construct number lines using positive and negative integers. They convert between decimals and fractions.

Learners explore the concept of fractions. For this fractions lesson, students perform basic operations such as addition and subtraction with fractions. Learners play a game on the computer called 'Fraction Four' that gives students...
