Young mathematicians access a website that leads them through three activities that enable them to practice their rounding and estimation skills when it comes to numbers and math word problems. There is also a very good worksheet...

Young scholars learn about the kinds of fossils and what scientists can learn from them.  In this earth science instructional activity, students are told how engineers and paleontologists work together.  Then young scholars...

Students examine heat transfer using energy efficient houses.  In this heat transfer lesson students calculate the heat that is transferred between a system and its surroundings.

Students collect samples in the field, analyze them using various tools and instruments, then present their results and interpretations. They examine igneous and metamorphic rocks in detail and interpret petrologic data.

Students, after watchin the story What Does This Show, summarize everyday life in ancient Egypt by writing about a typical day in the life of an Egyptian man or woman

Ninth graders discuss the aspects of culture and what makes them unique. In small groups, 9th graders use digital cameras to take photos. Groups use their pictures to create a PowerPoint presentation storyboard of their culture.

Students, in groups, discuss questions about a protest in London, England. They examine the differences between living in the city and the country.

Young mathematicians represent a triangle with a matrix and use the determinant to find the area of three given triangles. Learners also verify the formula for area of a triangle. 

Young scholars explore the use of imagery in writing. In this writing lesson, students create a writing piece that features sensory images without resorting to the use of clichés.

Students create and analyze slope fields. In this calculus lesson, students create a visual of differential equations. They use the Ti Navigator to create slope fields.

High schoolers differentiate lines and angles using betweenness in this geometry lesson plan. They differentiate angles and lines using Cabri Jr. and analyze the data and make conjecture.

Young mathematicians solve and graph piecewise functions in this calculus lesson. They integrate linear functions containing restrictions and graph their answers using the TI.

Young scholars explore linear functions in a crime solving context. They collect and analyze data using linear equations, then interpret the slope and intercepts from a linear model.

Your mathematicians solve problems using geometric series in this pre-calculus lesson. They divide a unit square into very small pieces and identify the reasoning behind the sum of a series being less than one.

Learners explore the concept of evaporation rates in this evaporation rates lesson. They will try to identify the chemical that began a fire, perform an experiment where they use the evaporation rates to determine the unknown liquid, and...

Learners identify the critical points to a function. In this calculus lesson, students perform optimization of functions. They use the TI to create a visual of the graph.

Young mathematicians differentiate between logs and natural logs in this algebra lesson. They solve functions and logarithmic functions. Learners also graph and rewrite the exponential and log functions.

Scholars identify the domain of a rational function in this precalculus lesson. They identify the removable discontinuity and label what will make the denominator zero. Learners also describe properties of the graph as it relates to the...

Learners evaluate the relationship between rainfall and runoff of a small island for one year. In this rainfall vs. runoff lesson, students analyze the relationship between the rainfall and the runoff on Barro Colorado Island over a...

New skills are developed as young scholars use graphing calculators and ranger technology to capture and graph the sequence of bounces a ball makes when dropped. After recording the height of four or more bounces, they use the collected...

Students examine complex numbers. In this Algebra II lesson, students investigate two programs that involve complex numbers: the MANDELER Program and SYNDIV program.

Students construct the circumcenter of a triangle. In this constructing the circumcenter of a triangle lesson, students construct a triangle using Cabri Jr. Students draw perpendicular bisectors of the sides of the triangle. Students...

Learners revisit midpoint and segments by graphing on the TI or computer. This activity can be done with pencil and paper, but is more interactive if it is done on a TI-navigator.

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...
