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

Learners perform translation and reflection. They identify the coordinate points of the new graph and create a formula for the movement. They identify the pre-image the and after image.

Young scholars perform transformations on their graphs. In this algebra lesson, students identify the pre-image and image. They find and identify congruent shapes and isometry.

Young mathematicians solve composition of functions. They add, subtract, multiply and divide functions and then identify the domain and range of each function. An embedded animation shows three different applications of function...

Pupils solve polynomial functions by graphing. They factor rational expressions to find the roots of the equation and apply the rational zero theorem to find the zeros of a polynomial.

Pupils solve problems using integration by parts in this calculus lesson. Learners apply the product rule and integration by parts. They graph the equation and use the TI to observe the integration process.

Young mathematicians solve problems of logs and natural logs. They graph functions of natural logs on the TI and relate integrals to natural logarithms.

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.

Using elimination to find the point of intersection of two lines, students learn to solve systems of equation. They graph their solutions and use the TI to verify the solution.

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 define and graph properties of linear equations. In this algebra lesson plan, students write systems of equations to represent functions. They relate linear equations to the real world.

High schoolers write the equation of a circle. In this geometry lesson plan, students check the solution of a coordinate pair by evaluating them. They graph the circle given the equation and radius.

Students experiment with locating oil reserves. In this conservation lesson, students use a cardboard box to create sand, rocks, and an oil reserve (water balloon). They use a probe to dig around in the box to find the oil reserve and...

Young statisticians use and interpret measures of center and spread such as mean, median, and mode as well as range. They use box plots to represent their data and answer questions regarding the correspondence between data sets and the...

Take a functional approach to the national debt. Learners collect information about the national debt by decade and plot the data. They determine whether an exponential curve is a good fit for the data by comparing the percent changes...

Math rocks! Cavern design teams determine the rankings of rock types based upon desirability points. The points are connected to the properties of the rocks and their usefulness in building a cavern. 

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.

In this exploring slope worksheet, students solve and complete 4 different problems. First, they compare an object's weight on Earth to an object's weight on another planet using the information given. Then, students compare this...

Students read about the changes in the "new money" and then create a graph to represent various combinations of currency produced.

If you dropped a needle on a lined sheet of paper what is the probability that the needle will cross one of the lines on the page?  Surprise your class with how calculating this probability can approximate pi. This question is known...

Searching for a relatively interesting way to demonstrate Charles' Law? Here is a lesson in which pupils heat air inside a flask and then cool the flask to quickly cool the air. They make observations about what occurs during the...

Young scholars enter information about their heartbeats into a spreadsheet. They construct data displays and calculate statistics. They describe and justify their conclusions from the data collected.

Students study how to track seismic activity of the Montserrat volcano. They create graphs of the data, study the observation logs that accompany the data, and interpret the graphs in relationship to the logs.

High schoolers investigate linear, quadratic and exponential equations using the TI calculator. They identify relation and functions using ordered pairs, graph the data, analyze the data, and relate it to real-world situations.
