The Mathematics CKT subtest measures what elementary teachers need to know to solve, explain, diagnose, and represent math ideas.
HiraEdu tutors help candidates prepare for the 85 minute Praxis Elementary Mathematics CKT 7813 subtest with domain review, numeric-entry accuracy, four-function calculator practice, student-error analysis, and CKT-style explanations.
ETS lists Praxis Elementary Education: Mathematics CKT 7813 as a computer-delivered 85 minute subtest with 52 selected-response and numeric-entry questions and an on-screen four-function calculator.
ETS lists 85 minutes for Praxis Elementary Mathematics CKT 7813.
The subtest contains 52 selected-response and numeric-entry questions.
Counting and Operations with Whole Numbers is the largest category at about 16 questions, or 30%.
ETS states that an on-screen four-function calculator is provided.
Praxis 7813 asks candidates to apply elementary mathematics knowledge to teaching tasks. HiraEdu plans include not only solving problems, but also interpreting student strategies, identifying misconceptions, choosing representations, and evaluating explanations.
Counting and whole-number operations plus place value and decimals account for more than half of the subtest. Prep should include base-ten reasoning, operation meanings, algorithms, estimation, decimal structure, and student error patterns.
Fractions, ratios, early equations, measurement, and geometry require flexible representations. Candidates should practice number lines, area models, arrays, equations, diagrams, units, shapes, and explanations that make student thinking visible.

Praxis Elementary Education: Mathematics CKT 7813 is one of the Content Knowledge for Teaching subtests in the 7811 series. ETS lists an 85-minute computer-delivered subtest with 52 selected-response and numeric-entry questions, and an on-screen four-function calculator is provided.
HiraEdu prepares candidates around the official ETS category weights: Counting and Operations with Whole Numbers at about 30%, Place Value and Decimals at about 25%, Fractions, Operations with Fractions, and Ratios at about 25%, and Early Equations and Expressions, Measurement, and Geometry at about 20%. The CKT format emphasizes both student-curriculum knowledge and specialized teaching knowledge, such as interpreting a student's mathematical misunderstanding from a pattern of errors or choosing an example that supports a particular concept.
ETS lists 85 minutes for the Mathematics CKT subtest.
The official ETS Study Companion lists 52 questions.
Counting and Operations with Whole Numbers is the largest category, with about 16 questions or 30% of the subtest.
Yes. ETS lists selected-response and numeric-entry questions for the Mathematics CKT subtest.
The subtest measures content knowledge for teaching, including specialized knowledge used to interpret student thinking, choose examples, and support elementary math learning.
Verify whether the candidate needs standalone 7813 or the full Praxis 7811 CKT combined test.
Build review around 30% whole-number operations, 25% place value and decimals, 25% fractions and ratios, and 20% equations, measurement, and geometry.
Practice diagnosing incorrect algorithms, fraction misunderstandings, place-value confusions, measurement errors, and incomplete explanations.
Combine selected-response and numeric-entry practice so candidates can enter exact values accurately while preserving enough time for teaching-scenario items.
Use the guide to self-serve, or talk to a coordinator if you need help mapping timelines, official requirements, or troubleshooting day-of logistics.
