This instructional activity is all about systems of equations and their graphs. Algebra learners create and solve systems of equation using tables and graphing. They identify the point of intersection of a system of equation, and...

Eighth graders discover the relationship between speed, distance, and time. They calculate speed and represent their data graphically. They, in groups, design a ramp for their matchbox car. The goal is to see who's ramp produces the...

Fifth graders complete a series of graphs by gathering information and using Excel to graph the information.  In this graphing lesson, 5th graders graph favorite desserts of the class. Student put their results into the...

Building blocks have more uses than simply entertaining children. Young mathematicians calculate the volume of a given cube, and then calculate the volume and surface area of a prism formed from multiple cubes.

Sixth graders listen to "Sixteen Tons" by Tennessee Ernie Ford and discuss what it means to owe one's soul to a store. In this mathematics lesson plan, 6th graders determine what a miner's income was minus his expenses graphing findings...

To take the longest path, go around—or was that go over? Class members measure scale drawings of a cylindrical vase to find the height and diameter. They calculate the actual height and circumference and determine which is larger.  

Scholars identify and continue the numerical pattern for the number of wheels on a train. Using the established pattern and its inverse, they determine whether a number of wheels is possible. Pupils finish...

Math scholars identify four different rock types in that strata and use this identification and data to construct a two dimensional geologic cross-section. They use data tables to construct a three-dimensional geologic cross-section.

See how design and geometry go hand in hand. The activity asks learners to use geometry to design a backyard garden given dimensions of each feature. Scholars work with ratios and scale to develop an accurate scale drawing that includes...

Let's paint the town equal parts yellow and violet, or simply brown. Pupils calculate the amount of blue and red paint needed to make six quarts of brown paint. Individuals then explain how they determined the percentage of the brown...

Parallelograms are pairs of triangles all the way around. Pupils measure to determine the area and perimeter of a parallelogram. They then find the area of the tirangles formed by drawing a diagonal of the parallelogram and compare their...

Each student or student team creates a web page. Learners research and make decisions for content of the page. Each web page should contain at least six images and six links, as well as any necessary commentary. Students indicate on the...

Your task today: count all the trees on a tree farm. To complete the assignment, learners first estimate the number of trees on a tree farm using random sampling. To improve their own response they then evaluate provided...

Students work in collaborative groups researching topics such as nutrition, the benefits of exercise on the body, dental and personal hygiene. They conduct interviews, create charts and posters, and report their results with a written...

Students analyze data related to amusement parks and create a spreadsheet to display the data. They read the data and predict which amusement park they think is safer, create a spreadsheet and graph, and write a proposal based on their...

Middle schoolers examine and compare traits of humans and crocodiles.  In this crocodile instructional activity students use a ratio to estimate the height of a person and compare that to a crocodile. 

"What is the theme of this story?" The very question can spark fear in the minds of readers and incinerate confidence. Here you will discover an exercise that shows how writers use the tools of setting, plot, conflict, and...

These aren't models made of clay. Young mathematicians model given population data using exponential functions. They consider different models and choose the best one.

Designers in Prague are not diagonally challenged. The mini-assessment provides a complex pattern made from blocks. Individuals use the pattern to find the area and perimeter of the design. To find the perimeter, they use the Pythagorean...

Students discuss, summarize, and express alternative positions regarding a study on adolescent sleep. They examine arguments for and against changing the school start time for high-school students, based upon the findings of a scientific...

  Wake up, sleepy head! High schoolers craft a creative presentation that represents how they feel when they wake up on a school morning. After the presentations, a reading of Academic Sleep Times and Academic Performance launches a...

Once learners realize what direct variation is, they see it's just a type of linear function. The lesson poses a general question that leads to the creation of the y = kx formula. The resource includes discussion prompts and ideas for...

The objective of this activity is to find the percent of the area of a two squares overlapping. Mathematicians find the ratio of area for the part that overlaps to the rectangle formed. The final answer is a percent as a rate per 100....

Determine the better deal. Pupils write the equation for the cost of printing tickets from different printers. They compare the costs graphically and algebraicaly to determine which printer has the best deal based upon the quantity of...
