CCSS↔TEKS crosswalk

STAAR follows the Texas Essential Knowledge and Skills (TEKS). Our missions are CCSS-aligned, and the elementary math TEKS overlap heavily with Common Core — the underlying math is the same. Each topic below shows both the TEKS readiness/supporting standard and the matching CCSS code so Texas families know exactly what's covered.

  1. 01

    Multiplication & Equal Groups

    TEKS 3.4K (Readiness) CCSS 3.OA.A.1

    Solve one-step and two-step multiplication problems within 100 using equal groups, arrays, and the commutative property.

    Key terms: Factor · Product · Array · Commutative · Equal Groups

  2. 02

    Division as Sharing

    TEKS 3.4K (Readiness) CCSS 3.OA.A.2

    Use partitive and quotative models to divide whole numbers within 100 — the inverse of the multiplication readiness standard.

    Key terms: Dividend · Divisor · Quotient · Remainder · Partition

  3. 03

    Fractions on a Number Line

    TEKS 3.3F / 3.3H (Readiness) CCSS 3.NF.A.2

    Represent and compare fractions with denominators of 2, 3, 4, 6, and 8 on a number line — the highest-weighted STAAR Grade 3 fraction strand.

    Key terms: Numerator · Denominator · Unit Fraction · Equal Parts · Whole

    Area of Rectangles

    TEKS 3.6C (Readiness) CCSS 3.MD.C.7

    Determine the area of rectangles by tiling and by multiplying side lengths — the geometry-measurement readiness standard.

    Key terms: Area · Square Unit · Tiling · Length · Width

  5. 05

    Perimeter & Missing Side Lengths

    TEKS 3.7B (Supporting) CCSS 3.MD.D.8

    Find the perimeter of polygons and solve for missing side lengths given the perimeter — frequently paired with area on STAAR.

    Key terms: Perimeter · Side Length · Polygon · Boundary

STAAR Grade 3 Math — FAQ

What's tested, how the CCSS↔TEKS overlap works, and how to print STAAR Grade 3 worksheets.

What does STAAR Grade 3 math cover?

The STAAR Grade 3 math test focuses on multiplicative reasoning (multiplication and division within 100), fractions on a number line with denominators 2, 3, 4, 6, and 8, area and perimeter of rectangles, and place value to 100,000. The five readiness/supporting standards above cover the highest-weighted reporting categories.

How do these CCSS-aligned missions help with STAAR (which is TEKS-based)?

Texas TEKS and Common Core overlap heavily for Grade 3 elementary math — the underlying mathematics is identical. Our missions use the array model, equal-groups model, and the number-line fraction model that both standards teach. Each topic above shows the TEKS readiness standard alongside the CCSS code our content cites.

Are the printable STAAR Grade 3 worksheets free?

Yes. Open the Grade 3 PDF Handbook below and use your browser's "Print → Save as PDF" on any topic guide to generate a free printable STAAR-aligned worksheet. No login or subscription required.

How long should my child practice for STAAR Grade 3?

15 minutes a day, four days a week, beats one long Saturday cram. Spaced retrieval is what keeps multiplication facts and fraction reasoning warm — start 8–10 weeks before the test for full coverage of all five readiness standards.

Is Inquiry AI Common Core aligned?

Yes. Every mission, handbook page, and topic hub is mapped to a specific CCSS code (visible in the page header). The curriculum follows the CCSS coherence map: Grade 1 number sense → Grade 3 multiplicative thinking → Grade 6 ratio reasoning, with each grade building strictly on the prior year's foundations.

What is inquiry-based learning, and how does Inquiry AI apply it?

Inquiry-based learning starts with a question, not a formula — students explore, hypothesize, and verify before being told the rule. In Inquiry AI, every mission opens with a "Discovery" step (manipulate the model), then "Abstraction" (write the equation), then "Reflect" (apply to a new case). The procedure is never given upfront; learners derive it from their own observations.

How is Guided Discovery Learning different from "just letting kids figure it out"?

Pure discovery is inefficient — kids hit a wall and quit. Guided Discovery scaffolds the path: a careful sequence of questions, models, and adaptive hints leads the learner toward the insight without revealing it. Inquiry AI's hint system fires automatically after ~15s of hesitation or on the first mistake, escalating from a Socratic nudge to a worked example only when needed. Mistakes are diagnosed via "misconception keys" so the hint matches the actual wrong-thinking pattern.

What does it mean for a math platform to be "Socratic"?

Socratic teaching answers a question with a better question. Instead of "the answer is 12", the system asks "if you had 3 groups of 4, how could you skip-count?" The goal is to externalize the learner's reasoning so they hear themselves think. Every Inquiry AI hint follows this pattern: nudge → reframe → analogy → only then a worked example, in that order.

What is the Concrete-Pictorial-Abstract (C-P-A) approach?

C-P-A is the Singapore Math sequence proven to deepen number sense: first manipulate physical objects (Concrete), then draw pictures of them (Pictorial), and only then write equations (Abstract). Inquiry AI structures every mission as exactly these three steps — a manipulative, a picture/grid model, and finally the equation. Skipping straight to symbols is the #1 cause of math anxiety; the platform refuses to do it.

Why does Inquiry AI let kids "struggle" before showing the answer?

Research on "productive struggle" shows that 20–60 seconds of focused effort BEFORE help dramatically improves long-term retention — the brain encodes the strategy more deeply. Inquiry AI's hint timing is calibrated to this window: short enough to prevent frustration, long enough to lock in the learning. Parents can adjust the threshold in settings if a learner needs faster scaffolding.
