11 OnTRACK Grade 8 Math: Proportionality

Students learn to to use proportional relationships to describe dilation; explain proportional and non-proportional relationships involving slope; and use proportional and non-proportional relationships to develop foundational concepts of functions.

###
6 OnTRACK Algebra I: Properties and Attributes of Functions

Students will learn how to use the properties and attributes of functions.

###
Study Edge Chemistry

In Chemistry, students will conduct laboratory and field investigations and make informed decisions using critical thinking and scientific problem solving. Students will study a variety of topics that include characteristics of matter, use of the Periodic Table, development of atomic theory and chemical bonding, chemical stoichiometry, gas laws, solution chemistry, thermochemistry, and nuclear chemistry. Students will investigate how chemistry is an integral part of our daily lives (TAC §112.35(b)(1)).

###
Covalent Bonding: Electron Dot Diagrams

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

###
Taxonomy Standards

Given examples, students will recognize the importance of taxonomy to the scientific community.

###
Taxonomy: Major Groups

Given illustrations or descriptions, students will determine the classification of organisms into domains and kingdoms.

###
Homeostasis: Ecological Systems

Given images, videos, or scenarios, identify and describe the responses of organisms, populations, and communities to various changes in their external environment.

###
Biological Systems: Homeostasis

Identify and describe internal feedback mechanisms involved in maintaining homeostasis given scenarios, illustrations, or descriptions.

###
Relationships Between Organisms: Food Chains, Webs, and Pyramids

Given illustrations, students will analyze the flow of matter and energy in food chains, food webs, and ecological pyramids.

###
Organisms' Adaptations

Given scenarios, illustrations. or descriptions, the student will compare variations and adaptations of organisms in different ecosystems.

###
Cell Homeostasis: Osmosis

The focus of this resource is cell homeostasis and, more specifically, osmosis. Students investigate the concept through a virtual lab, recording and analyzing data, creating sketches to represent vocabulary, and discovering the role of aquaporins in water transport through the cell membrane.

###
What’s Trending with the Elements?

This resource, aligned with Chemistry TEKS (5)(C), provides alternative or additional tier-one learning options for students using the periodic table to identify and explain trends.

###
Writing Verbal Descriptions of Functional Relationships

Given a problem situation containing a functional relationship, the student will verbally describe the functional relationship that exists.

###
Writing Inequalities to Describe Relationships (Graph → Symbolic)

Given the graph of an inequality, students will write the symbolic representation of the inequality.

###
Writing Inequalities to Describe Relationships (Symbolic → Graph)

Describe functional relationships for given problem situations, and write equations or inequalities to answer questions arising from the situations.

###
Connecting Multiple Representations of Functions

The student will consider multiple representations of linear functions, including tables, mapping diagrams, graphs, and verbal descriptions.

###
Writing the Symbolic Representation of a Function (Graph → Symbolic)

Given the graph of a linear or quadratic function, the student will write the symbolic representation of the function.

###
Determining Parent Functions (Verbal/Graph)

Given a graph or verbal description of a function, the student will determine the parent function.

###
Determining Reasonable Domains and Ranges (Verbal/Graph)

Given a graph and/or verbal description of a situation (both continuous and discrete), the student will identify mathematical domains and ranges and determine reasonable domain and range values for the given situations.

###
Interpreting Graphs

Given a graph, the student will analyze, interpret, and communcate the mathematical relationship represented and its characteristics.
