Fifth graders investigate the symmetry of pattern block shapes. Students, working in groups determine whether each shape has line symmetry, rotational symmetry or both kinds of symmetry. Students determine how many lines of symmetry the...

Eighth graders conduct a "Length of Day Symposium." They complete a variety of activities and explorations regarding the earth's rotation, its revolution around the sun and the cyclic changes in climate and energy distribution on the...

Groups of two to four work together to design, construct, and experiment with a boat. Each boat must include all of the major parts of a real ship, be less than 12 inches long, and be able to carry a load up twice its own weight in calm...

An online animation demonstrates how the lock system between Lake Superior and Lake Michigan works. Pupils then construct their own models of the lock system out of shoe boxes that they bring from home. This is an educational activity...

Students design and create a garden. They select flowers in small groups and research them. They draw a diagram of the landscape for their garden and plant flowers and observe them as they grow.

Students explore the value of land and the importance of conserving it as a limited resource. They observe a experiment where an apple represents the earth. From the demonstration, students visually see the fractions and percentages that...

Have a class discussion on diversity. With your class, explore the ideas of prejudice, fear, suspicion and individual rights. Discuss the benefits of uniqueness and how diversity contributes to strength and unity.

Fifth and sixth graders use food and candy to help them represent division of fractions and develop algorithms to solve fraction problems. They discuss dividing whole numbers by fractions. Pupils use sticks and chocolate bars to...

Students study the law of sine and cosine. In this pre-calculus lesson, students create a triangle and identify the different ratios of a non-right triangle. They use the properties of sine and cosine to solve.

Sixth and seventh graders study the concept of finding the percent of a number. They calculate the percent of any given number. Pupils describe ways to use calculating percents in their daily life, and change percents into decimals,...

Plug in this presentation for a quick start to your day. The class reviews the 6 times tables how they relate to division and then work through patterns to build logical reasoning and sequencing skills. A wonderful warm up or problem...

Students talk about mathematical language.  In this talking about your name lesson, students use the letters in their own name to review math vocabulary and concepts.  

Third graders observe angles in their classroom and create an angle finder to represent them.In this angles activity, 3rd graders classify angles as acute, obtuse, right or straight. Students find the differences and similarities in angles.

This lesson introduces students to the ideas involved in understanding fractals. They develop a sense of infinity, self-similarity and recursion and

Learners describe how the sun heats the Earth, explain the nature of infrared light, explain how thunderstorms are formed and use infrared maps to predict severe weather.

Students decide where to locate ice cream stands in a town so that no one has to travel too far to buy a treat. The problem-solving strategies for this problem give students a chance to decide what makes a solution satisfactory.
