This activity will use tuning forks and the CBR to gather sound wave data for students to use to write Sine (or Cosine) functions. In this activity we study waves of known musical notes before studying waves of unknown musical notes. I...

Students can use this LearningCheck item bank to prepare for the ITBS exam.

Different properties of the elements of the periodic table will be plotted and from this, a system of organization for the elements will be developed.

This lesson introduces students to Activity Center and is intended to help students interpret representations of functions of two variables. The Activity Center will be used to investigate equations that represent a company's income,...

In this activity the Students can use Cabri Jr. to investigate the Triangle Inequality Theorm and make conjectures about their findings.

Students study the distribution of sample proportions with a simulation. They find a small sample size leads to skewed distribution and as the sample size increases, the distribution becomes more normal.

Based off of the hit television show NUMB3RS, this activity shows students how money invested at different interest rates grow differently. The lesson focuses on aspects of interest such as compounding, length of time between...

Students take a numerical and tabular look at finding the maximum value of an open box constructed by folding a rectangular sheet of material with cutout square corners. They also understand the concepts of independent and dependent...

In this activity, students will develop and test rules for rounding whole numbers and decimal fractions. They will use the information to solve real-world problems.

Students will practice their knowledge of circle equations in the y= form by matching equations with pictures of various circles.

Since running a race car is VERY expensive, race engineers know a great deal about how speed, time and distance relate. In this activity, you will investigate the relationship between distance traveled, speed and elapsed time. You will...

The student will graph ordered pairs on a coordinate plane and use graphing to solve problems involving cartography.

This questions set tests the following knowledge and skills in parametrics: graphing parametric equations; projectile motion; conversions between parametric and nonparametric forms. Solutions are provided.

Students' use a motion detector to examine how different types of motion affect the shape of the distance versus time plot. They explore how changes in direction and other factors affect the shape of the plot.

Students can use the substitution method of solving systems of linear equations.

In this activity, students construct kites and investigate their properties. They also relate the properties to squares and rhombi.
