Start with Grade 4 Math Practice
Use this general Grade 4 math practice test to check your skills, then review the missed topics below. It is independent practice, not an official state assessment or a replica of its timing, scoring, or question types.

Use the topic directory below for grade-level skills and linked standards. The general practice test is an independent learning tool, not an official state test. Timing and calculator rules depend on your school or testing program.
California Grade 4: connect practice to a classroom target
Use California curriculum source to check the expectation your class is studying. The topic directory provides general lessons; it is not a complete state alignment. These selected learning references give you more precise ideas to compare with an assignment. Common Core-style codes are Common Core references, and other codes come from the existing planning reference. Confirm current state wording and placement before treating either as an official local requirement.
- 4.OA.1
- Interpret a multiplication equation as a comparison,
- 4.NBT.1
- Recognize that in a multi-digit whole number, a digit in one place represents ten times what it represents in the place to its right
- 4.NF.1
- Explain why a fraction a/b is equivalent to a fraction (n×a)/(n×b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions
- 4.MD.1
- Know relative sizes of measurement units within one system of units including km, m, cm; kg, g; lb, oz.; l, ml; hr, min, sec. Within a single system of measurement, express measurements in a larger unit in terms of a smaller unit. Record measurement equivalents in a two-column table
- 4.G.1
- Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures
Choose practice from the explanation
Ask the student to explain one of the ideas above with a drawing, model, table, or short calculation. If the explanation is unclear, open the related lesson before assigning a mixed test. If the idea is understood but the calculation is unreliable, choose a focused worksheet and review the strategy afterward.
Keep the classroom target, the resource used, and the next step together in a study note. A topic quiz can guide review; its score is not an official state performance level. Revisit the skill in a new context after a few days.

California CAASPP Grade 4 Math FAQ
What is the CAASPP Grade 4 math test?
The CAASPP (California Assessment of Student Performance and Progress) is California’s Grade 4 mathematics assessment. The linked activities are independent Grade 4 practice. Their question count, timer, scoring, and item types may differ from the official assessment. Use the directions inside each activity.
Can I use a calculator?
A calculator is not a standard tool on Smarter Balanced mathematics in grades 3–5. Individual accommodations are handled by the school. Check the official accessibility guidance before the assessment.
How long is each practice test?
Read the timer and question count shown in the practice activity you open. These are practice settings, not a statement of the official assessment’s duration or scoring.
Is it free?
The linked general practice and topic resources are available separately from optional books. Check each activity’s directions and access requirements. The study guide and bundle are optional next steps.

Make This Your California CAASPP Starting Point
Take a timed practice test, find your weakest topic, and study it with the linked lessons, worksheets, and the CAASPP study guide.
Start a practice testUse California’s domains to organize review
The directory uses Common Core domain labels: 4.OA for operations, 4.NBT for base-ten numbers, 4.NF for fractions, 4.MD for measurement and data, and 4.G for geometry. These are broad groups, not a full standard-by-standard alignment. Use California’s mathematics resources and your classroom assignments to choose the next skill. Independent practice scores are not official CAASPP results.

California Grade 4 Math: study questions
How should I choose a Grade 4 math study target?
Choose a current classroom target, find the matching learning reference, and use a lesson or available practice resource to check understanding. State documents control local wording and placement; shared reference codes are not a certified crosswalk.
Official source ↗Are these activities official state assessments?
These are independently published learning resources. A practice score does not predict or replace an official state score. Use the directions in each activity and consult your school for official testing and accommodation rules.
