Texas Essential Knowledge and Skills for Mathematics

Teacher's field guide

What Students Need to Do: Students show mathematical relationships and reasoning with tables, graphs, equations, diagrams, words, or physical models. They choose a useful format and connect it clearly to other formats.
What Mastery Looks Like: Students select a useful model, label it clearly, and use it to explain their reasoning. They can translate between a table, graph, equation, diagram, and written statement without changing the meaning.
Common Misconceptions: Students may leave axes, units, table columns, or diagram parts unlabeled. They may create several displays that do not match or copy numbers without showing the mathematical relationship.
How to Assess It: Give students a table showing x-values 0, 1, 2, 3 and y-values 5, 8, 11, 14, then ask for an equation, graph, and explanation.

Lesson moves

Build growing patterns with color tiles, then record each stage in a table, sketch a graph, and write an equation.
Display two models of the same relationship and ask students to write which communicates the pattern more clearly and why.
Give groups matching cards with tables, graphs, equations, and descriptions, then have them assemble and justify complete sets.
Compare two phone plans by organizing their monthly costs in tables, graphs, equations, and a written recommendation.
