Teach your class how to solve problems using the triangle sum theorem. In this geometry lesson, students identify the missing angles in a triangle using the sum theorem. They graph triangles on the TI and moves the sides around to create...

Learners slice cones and identify the different conics formed. They then derive the formula to solve problems involving cones. Pull out the TI calculators to visualize the slicing and the different parts and properties created.

Students explore air pollution. In this ecology and air pollution lesson, students perform an experiment in which a Vaseline coated lid is placed inside and outside the classroom. Students make predictions and then record what they see...

Learners solve equations using a given derivative. In this calculus lesson plan, students identify the rise of fall of each function. They use the calculator to find the derivative.

Find the length of an arc. Students relate central angles to the area and length of a sector and graph circles on the TI to make predictions.

Students factor polynomial equations. In this algebra lesson, students identify the zeros of the equations. They use algebra to rewrite word problems using symbols.

Students identify and use the commutative properties of addition and multiplication, associative properties of addition and multiplication, and the distributive property of multiplication over addition.

Pupils identify and define intersecting lines and vertical angles. They draw two intersecting lines and measure one pair of vertical angles. Learners will also move a line to change the angles of a figure and describe the changes in the...

Pupils investigate the properties of a rotation as they use technology (Cabri, Jr.) to observe the relationship between the pre-image and the image formed by the rotation. The lesson provides ample opportunity for learners to conjecture...

Spur a discussion of germs using this lesson. Learners conduct an experiment with potatoes to determine how germs are transmitted. They then discuss ways to prevent the spread of germs. The emphasis is on hand washing.

Students interpret information on a weather map in order to construct a graph, and discuss how the weather impacts their lives.

In this algebra worksheet, students identify the central tendencies as they solve a box and whisker plot graph. They identify the quartiles of the data. There are 4 questions with an answer key.

Second graders investigate dinosaurs. They explore various websites, submit questions to a paleontologist online, construct cut and paste model dinosaur skeletons, develop a graph to compare dinosaurs, and label pictures from online...

Students experiment to show rain drop splash and splash erosion. In this erosion lesson, students complete 3 experiments showing splash erosion and methods for controlling soil erosion. They complete a number of worksheets, learn...

Seventh graders are introduced to the concept of box-and-whisker plots. A step-by-step process for creating a box-and-whisker plot is provided. The goal of the lesson is that students study the components of a box-and-whisker plot and be...

Students develop procedures to explore the behavior of fish.  In this scientific experiment lesson students from a hypothesis, write a question, identify different variables and controls in their experiment. 

Students investigate the stages of succession in animal dung communities. They create a dung culture using fresh cow, goat or horse dung then record data on the fungal species that appear over a two week period.

Learners investigate vegetables. In this multi-subject lesson, students learn about vegetables and participate in several activities using vegetables. A list of 7 materials is included.

Students discover the types and amounts of particulate matter found in the air. They collect particulates using a Petri dish coated with Vaseline then classify and count the collection under a stereoscope.

Learners investigate how weather affects how plants grow. They collect data on weather and plant growth for a week and display the data on a graph. For a culminating experience they design a movie using software that shows plant growth...

Students test and identify soil and rock samples. In this rock and soil lesson, students video themselves gathering samples. Students test the samples and create graphs showing the results.

Students compare and evaluate the world's different seaweeds.  In this investigative lesson students study seaweed and the harvesting of it.  They then interpret the data collected and graph the seaweed production. 

Learners make a simple graph of labor supply and labor demand in the North and South in the early twentieth century. They conduct research to identify top contemporary African-American entrepreneurs.

Fourth graders investigate repeating and growing patterns. Models, graphs and words are used to describe, extend and represent patterns. Students use evidence from models and graphs to support the identification of patterns.
