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.

###
Uncovering Tone in Poetry

Students will interpret the tone of a poem, cite text evidence to justify their response, and research a synonym for the word they chose to expand their understanding of Tier 2 vocabulary.

Texas Courses Update

Professional development courses for CPE credit are transitioning to a new course platform—TEALearn; professional development courses are no longer available through the Texas Gateway. As part of this process, TEA has reviewed courses that were previously offered through the Gateway. This resource provides an update on current status and availability of Classic Gateway courses.

New Resource Link to Test

Here's the new resource link to test. Let's hope this is a go!

###
Covalent Bonding: Electron Dot Diagrams

Given descriptions, diagrams, scenarios, or chemical symbols, students will model covalent bonds using electron dot formula (Lewis structures).

###
Demonstration and Analysis of Dihybrid Crosses

The students will review related vocabulary, watch the teacher model a dihybrid cross, and then perform a dihybrid cross and answer questions about the outcomes with a partner.

###
Summarizing as a Reading Strategy

Students work collaboratively using reading and comprehension skills to demonstrate their mastery of summarizing a text or piece of literature.

###
Exploring Identity and Diving Deep into the Complex Meaning of Poetry

This lesson is designed to teach students to make complex inferences, choose specific text evidence that strongly supports the inference, and develop a coherent explanation of how the evidence strongly supports the validity of the idea within the genre of poetry.

###
Working with Literal Equations

The lesson will provide a conceptual basis for illustrating the parallelism between solving multi-step equations and translating literal equations into solutions for specified variables.

###
Types of Science Investigations

Students will distinguish between descriptive, comparative, and experimental investigations.

###
Experimental Design

Given investigation scenarios and lab procedures, students will identify independent variables, dependent variables, constants, and control groups.

###
Interpreting Scatterplots

Given scatterplots that represent problem situations, the student will determine if the data has strong vs weak correlation as well as positive, negative, or no correlation.

###
Making Predictions and Critical Judgments (Table/Verbal)

Given verbal descriptions and tables that represent problem situations, the student will make predictions for real-world problems.

###
Collecting Data and Making Predictions

Given an experimental situation, the student will write linear functions that provide a reasonable fit to data to estimate the solutions and make predictions.

###
Writing Expressions to Model Patterns (Table/Pictorial → Symbolic)

Given a pictorial or tabular representation of a pattern and the value of several of their terms, the student will write a formula for the nth term of a sequences.

###
Analyzing the Effects of the Changes in m and b on the Graph of y = mx + b

Given algebraic, graphical, or verbal representations of linear functions, the student will determine the effects on the graph of the parent function *f(x) = x*.

###
Writing Equations of Lines

Given two points, the slope and a point, or the slope and the y-intercept, the student will write linear equations in two variables.

###
Determining the Domain and Range for Linear Functions

Given a real-world situation that can be modeled by a linear function or a graph of a linear function, the student will determine and represent the reasonable domain and range of the linear function using inequalities.

###
Investigating Methods for Solving Linear Equations and Inequalities

Given linear equations and inequalities, the student will investigate methods for solving the equations or inequalities.

###
Quadratics: Connecting Roots, Zeros, and x-Intercepts

Given a quadratic equation, the student will make connections among the solutions (roots) of the quadratic equation, the zeros of their related functions, and the horizontal intercepts (*x*-intercepts) of the graph of the function.
