45-45-90 Triangles

To learn the pattern of the side lengths of a 45-45-90 triangle, students complete a gallery walk, a card sort activity starting with using the Pythagorean theorem, and activity to locate if there is an error in a presented problem and if so to identify what the error is.

TEA AP^{®} Biology

^{®}Biology

*AP ^{®} Biology* covers the scope and sequence requirements of a typical two-semester biology course for AP

^{®}students. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. AP

^{®}Biology was designed to meet and exceed the requirements of the College Board’s AP

^{®}Biology Framework, while allowing significant flexibility for instructors. Each section of the book includes an introduction based on the AP

^{®}curriculum as well as rich features that engage students in scientific practice and AP

^{®}test preparation. It also highlights careers and research opportunities in the biological sciences. Content requirements for AP

^{®}Biology are prescribed in the College Board Publication Advanced Placement Course Description: Biology, published by The College Board (http://ritter.tea.state.tx.us/rules/tac/chapter112/ch112d.html#112.62).

###
Can We Get There?

Students will calculate the rate of change and *y*-intercept from a real-world problem represented in a graph, a table, and/or an equation. They will then display and present their findings to the class.

###
Approximating the Value of Irrational Numbers

Given problem situations that include pictorial representations of irrational numbers, the student will find the approximate value of the irrational numbers.

###
Expressing Numbers in Scientific Notation

Given problem situations, the student will express numbers in scientific notation.

###
Drawing Conclusions about Three-Dimensional Figures from Nets

Given a net for a three-dimensional figure, the student will make conjectures and draw conclusions about the three-dimensional figure formed by the given net.

###
Converting Between Measurement Systems

Given a real-world situation with measurements in either metric/SI or customary units, the student will solve a problem requiring them to convert from one system to the other.

###
Determining if a Relationship is a Functional Relationship

The student is expected to gather and record data & use data sets to determine functional relationships between quantities.

###
Graphing Dilations, Reflections, and Translations

Given a coordinate plane, the student will graph dilations, reflections, and translations, and use those graphs to solve problems.

###
Graphing and Applying Coordinate Dilations

Given a coordinate plane or coordinate representations of a dilation, the student will graph dilations and use those graphs to solve problems.

###
Developing the Concept of Slope

Given multiple representations of linear functions, the student will develop the concept of slope as a rate of change.

###
Recognizing Misuses of Graphical or Numerical Information

Given a problem situation, the student will analyze data presented in graphical or tabular form by evaluating the predictions and conclusions based on the information given.

###
Evaluating Methods of Sampling from a Set of Data

Given a problem situation, the student will evaluate a method of sampling to determine the validity of an inference made from the set of data.
