Most adults remember learning about the Pythagorean theorem, but they don't all remember how to use it. The emphasis here is on developing an intuitive understanding of how and when to use the theorem. Young mathematicians explore...

Using the Pythagorean Theorem to solve for missing angles, students evaluate right triangles and their properties.

Linear or not linear — that is the question. The lesson plan has class members translate descriptions into algebraic expressions. They take the written expressions and determine whether they are linear or nonlinear based upon the...

Students participate in a series of hand-on, online, and multimedia activities to examine 2 dimensional and 3 dimensional shapes. They describe common geometric solids. They construct rectangular prisms using straws and ribbon.

High schoolers analyze the vertex form of a parabola and find an approximate fit of a model. They explain the quadratic parabola function and its properties by developing quadratic models. They use translation and dilation to change the...

Students build a solar oven. In this Science lesson, students construct a functional solar oven. Students design the oven and explain the energy concepts involved.

Seventh graders build their own Clinometer and using the tangent of angles, estimate the height of trees. Then these students develop and lesson to show whole class and determine the tallest tree on school property.

Discover an interesting mathematical object that your algebra learners will enjoy investigating. Their adventure will lead them to the generation of a finite geometric series.

Here is a great instructional activity on constructing line graphs. Learners identify common characteristics of birds, ants common needs of all living things. They also write a story from the perspective of an ant or a bird that has lost...

A series of independent learning activities teaches learners about global warming as it relates to economics and industrialization. The culminating project requires them to create a multimedia presentation identifying the problems,...

Learners use the Frayer model during problem solving. In this problem solving lesson, they examine multiple methods of data collection to solve real world problems. Resources are provided.

Assist your class with each angle of geometry as they use exterior angles to form linear pairs with adjacent interior angles. They cover multiple vocabulary terms and work practice problems, complete with justifications, before...

Great real-world math application! Have the class compare and contrast their estimated home price and income data with actual data. In groups, they participate in simulations to discover how the housing market and mortgages operate....

Multiplying fractions by whole numbers is the focus of the math instructional activity presented here. There are three activities outlined in the instructional activity along with a nifty game learners play on the computer that...

Two lessons for the price of one! Learners use algebra tiles to multiply binomials in the first instructional activity, Next, they use their knowledge from the first instructional activity to factor trinomials into two binomials.

Youngsters sort M & M's by color. They graph the M&M's by color on a graph. This classic lesson is a wonderful way to introduce the concept and technique of graphing to young mathematicians. Pairs of kids can make up their own...

Learners examine concept of time, and explore difference between analog and digital clocks; students make art project to represent time and create a time-story problem and solution.

Learners explore elements by analyzing everyday objects and materials in class. In this carbon lesson, students define several vocabulary terms such as carbon dioxide, hydrocarbon, and carbonate. Learners view a group of items,...

High schoolers attempt an assessment task requiring them to find the radii of inscribed and circumscribed circles of a right triangle with given dimensions. They then evaluate provided sample responses to consider how to improve...

What middle schooler does not enjoy an occasional online game? In this lesson play, you will find embedded links to an online probability game, and informative pages about how division is used in probability, the concept of tree models,...

Young mathematicians draw, create, and describe different shapes using triangles. They discuss attributes of the original and created shapes. Pupils classify the created shapes and draw and write in mathematics journals to communicate...

Mathematicians practice communicating why the sum of two multiples of a number results in another multiple of that number. Encourage learners to construct a viable argument by applying the distributive property or by drawing a diagram....

During a three-part lesson, learners make a cabbage juice pH indicator and use it to analyze the waste products of yeast after feeding them with sugar. The intent is to demonstrate how living organisms produce carbon dioxide, which is...
