Texas Instruments activity where students will create equations with two or more variables to represent relationships between quantities. They will also graph equations on coordinate axes with labels and scales.
Lesson focuses on having students prove that dilations map an angle to an angle with equal measure.
Lesson exploring angle preservation in dilations.
Students prove that a dilation maps a ray to a ray, a line to a line, and a circle to a circle.
Lesson on dilating shapes and lines with centers of dilation at center and not at center.
Assessment item requiring students to use information in a two-way table to calculate a probability and a conditional probability.
This lesson will introduce hypothesis testing.
In this activity students will have the opportunity to collect and explore data. Students will perform an experiment in order to test The Psychic Staring Effect. The Psychic Staring Effect is the idea that people can sense that they are being stared at. The activity can be used to illustrate large-sample confidence intervals and hypothesis tests on proportions; two-way table analysis and the chi-square test; the binomial distribution and the binomial test.
This task has students explore the relationship between the three parameters a, h, and k in the equation f(x)=a(x−h)^2+k and the resulting graph.
The square root of -1 (i) is introduced in this lesson.
Students discover that the values of the adj/hyp and opp/hyp ratios in a right triangle depend solely on the measure of the acute angle by which the adjacent, opposite, and hypotenuse sides are identified.
Texas Instruments activity where students use a simulation to find the experimental probability of independent events.
This video goes over the multiplication rule for independent events using a test taking example.
Practice worksheet with independent and dependent events.
This Khan video explains independent versus dependent events.
Students will know an informal proof of the angle-angle (AA) criterion for similar triangles and students will present informal arguments as to whether or not triangles are similar based on the AA criterion.
This lesson is designed to introduce conditional probability by building on students' prior knowledge of probability. The lesson focuses on showing the entire sample space to find conditional probabilities. The lesson incorporates examples with Venn diagrams and two-way tables. It wraps up with a definition of independent events.
This video goes over fractions in exponents.
This video explains reflective symmetry and lines of symmetry.
This video explains what square-root equations are, and shows an example of solving such an equation and checking for extraneous solutions.
