In this algebra worksheet, students calculate the slope of a line. They graph a linear equation given the slope and y-intercept and identify the slope and y-intercept given a linear graph. There are 15 questions.

High schoolers define several vocabulary terms related to chemicals and toxicology. Students calculate chemical concentrations in water and explain the toxicological principles that govern safety of substances. High schoolers conduct an...

Students investigate the effect of a chemical (they choose) on the germination of seeds. They calculate % chemical concentrations in water, form a hypothesis, and discuss the ethics of using animals in biomedical research.

Pupils investigate the number of points needed to determine a unique circle in a plane. Using Cabri Jr., they apply construction techniques to generate a circle that passes through a given number of points.

Learners investigate the special properties of an altitude, a median, and an angle bisector and explore how these special segments divide the area of a triangle. The dynamic nature of Cabri Jr. allows pupils to form and verify conjectures.

High schoolers investigate the relationship between angle measures and sides of a triangle and the relationships among the three sides of a triangle. The use of technology (Cabri, Jr.) allows learners to make and test conjectures as they...

Learners use sliders to change the parameters of functions and examine how shifting parameters affects a graph. They identify the parameters of functions, find vertical and horizontal stretches, then calculate the scale factor and other...

Pupils write systems of equations in an augmented matrix and enter it into their calculator. They use the reduced row echelon function on the calculator to solve the system of equations.

Young scholars investigate the properties of quadrilaterals formed by angle bisectors of a given quadrilateral and quadrilaterals formed by the medians of quadrilaterals. This Cabri Jr. lesson provides opportunity for conjecture and...

Students investigate parabolas and their equations.  In this parabolas and their equations lesson plan, students graph quadratic equations on their graphing calculator.  Students find the axis of symmetry of a parabola. ...

Eleventh graders investigate the way credit cards work when collecting interest. For this algebra lesson, 11th graders investigate the growth of interest exponentially when using a credit card. They calculate what the cheapest rate is to...

Learners create an exercise and nutrition program. For this interdisciplinary lesson, students use calculations of exercises plus their corresponding effects on the body and nutritional values of food to derive a health plan. Learners...

In this measuring chemicals worksheet, high schoolers investigate measurements of an aluminum slab including the length, width, height, mass, volume and density. They do the same for a piece of aluminum foil and they compare their...
