Students learn to use manipulatives and calculators to explore what happens when they change one number at a time in an addition number sentence. They record and develop the pattern that develops.
This investigation uses Cabri Jr. and a cleaver rotation of a triangle to "prove" that the angles in a triangle add up to 180. This could be used to reinforce triangles and paralled lines as well as introduce the concept of rotating an object.
In this activity, students will investigate properties of angles and arcs formed when chords, secants, and tangents intersect and intercept arcs in a circle. They discover several important theorems concerning circles and arc sizes. They make use of the Central Angle theorem, which ensures that the measure of a central angle of a circle is equal to the measure of its intercepted arc.
This StudyCard stack teaches and tests on the exponential function. Shows connection between the function parameters and the resulting geometric behaviors of the exponential function. Use with Foundations for College Mathematics, ch. 6.1.
This StudyCard set teaches and tests on the quadratic function. Shows connection between the function parameters and the resulting geometric behaviors of the quadratic function. Use with Foundations for College Mathematics, ch. 2.5, 9.1.
Questions cover the binomial distribution. Students identify characteristics of a binomial distribution and calculate probabilities for different ranges. Binomial mean and variance are covered in the link between the binomial and normal distribution.
This set of questions pertains to the binomial formula and Pascal's triangle. Students will find terms of an expansion and investigate combinations. Questions are short answer, true/false, and multiple-choice; solutions are included.
This set contains statistics questions regarding bivariate data: scatter plots, the least-squares regression line, and their interpretation. The student is asked about the meaning of the various strengths and directions of linear correlation.
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 variables.
In this activity, students will make their own finger signs for the numbers from zero to ten. Students will relate each finger sign to its numeral and then explore number sentences using the calculator.
This StudyCards stack enables students to review information about the organelles of eukaryotic plant cell. They are tested on their ability to describe the structure, location, and function of different cell organelles.
In this activity, students observe the centripetal acceleration of an object in uniform circular motion. Relate the changes in velocity and radius to the centripetal acceleration.
