What’s on grade 8 math
The CAASPP reports grade 8 math in 2 categories. The practice set covers each of them:
Concepts and Procedures
- Estimating square roots between whole numbers
- The rules of exponents
- Square roots and cube roots
- Scientific notation
- Slope from two points or a table
- Equations with variables on both sides
- Translations, reflections and rotations on the coordinate plane
- Angles in triangles and where parallel lines are crossed
- Volume of cylinders, cones and spheres
Mathematical Practices
problem solving, modeling and data analysis, communicating reasoning
- Rational and irrational numbers
- 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
- Similar figures and dilations
- The Pythagorean theorem
- Scatter plots: association and lines of fit
- Two-way tables and relative frequencies
- The CAASPP checks the California Common Core State Standards.
- Calculators: No calculator in grades 3-5. Grades 6-8 mix calculator and non-calculator items, with an embedded Desmos calculator on calculator items.
How to help at home
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.
Little and often
A short set a few times a week does more than a long session the week before.
Use real life
Prices at the store, recipes, distances and times on a trip: grade-level math is everywhere.
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.

See Thena explain the ones they missed
With an account, Thena goes over every question your child gets wrong: she puts it back on her board, finds the slip and works it through out loud, then gives them one like it to do alone.
