What’s on grade 8 math

The STAAR reports grade 8 math in 4 categories. The practice set covers each of them:

Numerical Representations and Relationships

  • Rational and irrational numbers
  • Estimating square roots between whole numbers
  • The rules of exponents
  • Square roots and cube roots
  • Scientific notation

Computations and Algebraic Relationships

  • Slope from two points or a table
  • Equations with variables on both sides
  • Systems of two linear equations
  • What makes a relation a function
  • Linear functions as models: rate of change and starting value
  • Telling linear and nonlinear functions apart

Geometry and Measurement

  • Translations, reflections and rotations on the coordinate plane
  • Similar figures and dilations
  • Angles in triangles and where parallel lines are crossed
  • The Pythagorean theorem
  • Volume of cylinders, cones and spheres

Data Analysis and Personal Financial Literacy

  • Scatter plots: association and lines of fit
  • Two-way tables and relative frequencies
  • Money: simple and compound interest
  • The STAAR checks the TEKS (Texas Essential Knowledge and Skills).
  • Calculators: Not allowed in grades 3-7 unless the student qualifies for a calculator accommodation. Required in grade 8.

How to help at home

  1. Do one set, then talk

    After a set, look at the ones they missed together. Ask how they got their answer before saying what the right one is.

  2. Little and often

    A short set a few times a week does more than a long session the week before.

  3. Use real life

    Prices at the store, recipes, distances and times on a trip: grade-level math is everywhere.

  4. Keep it calm

    The test checks how the year went. A good night’s sleep helps more than cramming.

For the real test’s screens and tools, try the state’s official practice.
