Students explore multi-step equations. In this pre-algebra/algebra I instructional activity, students use the TI-nspire computer algebra system to check the steps they used to solve multi-step equations and equations with variables on...

Here is a set of lessons that explore conics in a number of different ways. Starting with modeling how a conic is produced by the way a plane cuts the cone, to solving complex word problems, algebra learners progress through a series of...

Students examine and chart data about safety hazards and unsafe situations. In this safety hazard lesson, students examine newspapers and web sites to investigate injuries from safety hazards. They make a spreadsheet using the data and...

Bar graphs are used as a way to study voting patterns in the United States. A variety of statistical data is presented in the graphs, and pupils must interpret the data in order to make a report to the class. Three excellent graphs,...

Simulate chariots and driver and practice rounding numbers with your class. In teams of three, they race to the finish line where the teachers asks the chariot driver to round a certain number. They take turns being the driver.

Fifth graders develop a questionnaire to investigate weather in different part of the US. They investigate how weather in one part of the country affects weather in another part. They predict the development of hurricanes.

Students read a letter from George Washington requesting them to identify on a map a location that would stop the advance of British warships. They choose a location and justify their choice.

Students use the internet to gather information on the Japanese Gardens. They discuss topics with a horticulturist and build a replica of the gardens at their school. They work together to identify different types of plants.

Students demonstrate whole numbers through one thousand using base ten blocks. They model and describe given numbers using ten blocks.

Seventh graders explore estimation, measurement, and probability. Students conduct surveys and create charts & graphs. They study the history of chocolate. Students design their own magazine advertisement or create a script for a...

Students convert volcano elevation from feet to meters.

Students, in groups, use longitude and latitude to locate various places on a map.

Pupils facilitate each student's comprehension of the different jobs on a ship and the job's evolutions over time. They compare/contrast certain jobs on a ship from history to today. Students work together in cooperative groups to...

Students investigate the concept of energy and focus upon the usage and the cost associated with it. They conduct research using a variety of resources while working in cooperative groups. Students graph the usage of energy as estimates...

Students investigate the Napoleon triangle theory. In this polygon lesson, students  differentiate between the boundary points, interior and lattice point of a polygon. They apply concepts of equilateral triangles to solve...

Students reinforce geometric concepts by playing "Guess My Solid." Through a process of elimination, they determine the shapes of mystery solids. Finally, students use various materials to construct their own geometric figures.

Students explore the concept of congruent triangles.  In this congruent triangles lesson, students use Cabri Jr. to construct two congruent triangles using circles.  Students determine if the two triangles are congruent by...

Students use the internet to research how biometrics is being used in the real world today. They work together to research hand geometry applications. They share their findings with the class.

Ninth graders discover what it means to "brainstorm." They explore a given simple number pattern and then, working in groups, brainstorm more complicated number patterns. They display them around the room and then solve the number...

Eighth graders practice using the LIST key on graphing calculators using the proper syntax. They work with the functions of mean, median, and mode in a teacher led instructional activity and then with a partner on a second data set. They...

Students create an original lesson plan about geometry and angles. In small groups they take pictures using a digital camera of obtuse, acute, right, and straight angles that they find at school. Students use the photos in a computer...

Eighth graders research, collect and interpret data about weather statistics. They record that data on spreadsheets. they create Powerpoint presentations on their individual or group research.

Fifth graders classify blocks according to their attributes. In this math lesson, 5th graders will identify attributes of blocks, sort them, then form the groups into a Venn Diagram, and write ratios using the attributes.

Fourth graders role play as contractors responsible for constructing a chain across the Hudson River. They apply math skills to determine the total weight, number of links, and cost of the project.
