Times Tables Practice

90 missions across Grades 3 and 4 covering the whole multiplication table — array model first, drill second, applied last. Three difficulty tiers per fact group.

Four classroom shapes

Map a tool to today's actual lesson.

Most edtech makes you bend your lesson around the product. We try to do the opposite — every surface above is a fit for at least one of these four classroom shapes.

Whole-class projector

Open a topic on the projector, walk through the array or fraction-bar model with the class, hand off to independent practice. Hint cues line up with the questions you are already asking.

Math centers / station rotation

Three different topic links → three stations. No printing, no usernames, no rotating logins. LocalStorage saves progress per device so kids resume mid-mission tomorrow.

Sub-day backup plan

Print the QR code that links to the topic hub. The substitute does not need an account, cannot enroll students in anything, and cannot affect tomorrow's lesson.

Mixed-level small groups

Each topic ships Seedling / Explorer / Challenger tiers. Same UI, different depth — differentiate within one group without students feeling tracked.

Teacher resource hub

Who this page helps, and where to go next.

Free K-6 math resources for teachers who need no-prep games, manipulatives, printable guides, and Chromebook-safe classroom links.

Best for

  • Elementary teachers planning a review block or math center.
  • Intervention teachers matching students to different difficulty tiers.
  • Homeschool and tutoring adults who need a standards-aligned path.

Problems solved

  • Teacher-facing resources are scattered across grade, topic, printable, and manipulative pages.
  • Classroom tools often require rosters before students can start.
  • Mixed-level groups need one topic with multiple difficulty tiers.

Second-round teacher intent expansion

Classroom use first, not another game catalog.

This hub is for teachers who need a usable path today: choose the classroom mode, open a grade or standard, then send students to a topic hub, guide, representative mission, or printable follow-up.

Search intent focus

Free math resources for teachers, no-prep math games, classroom math centers, Chromebook math practice, Common Core review games, and printable math worksheets for K-6 classrooms.

Best fit

Whole-class review

Project the topic guide or visual manipulative first, then move the class into the matching topic hub for independent practice.

Math centers and sub plans

Use a no-login route that works on classroom devices without roster setup, codes, or account recovery.

Intervention groups

Keep every student on the same standard while changing the depth through Seedling, Explorer, and Challenger missions.

Problems solved

  • Teacher-facing routes are scattered across grade pages, topic hubs, manipulatives, printables, and device notes.
  • Classroom tools often ask for rosters before students can start, which breaks a same-day lesson.
  • Mixed-readiness groups need one standard with different entry points, not a completely separate curriculum.
FAQ

For Teachers — FAQ

What teachers ask before adopting in their classroom.

01 What does "for teachers" actually unlock here?

Nothing locked, no upgrade. Every page on this site is free for teacher use, classroom display, and embedding in your school site or LMS. The /teachers/ hub exists because teachers asked for one place that maps each tool to a real classroom shape (whole-class lesson, math center, sub day, mixed-level group) instead of one giant alphabetical list.

02 Do I need a teacher account or class roster to use these?

No. There is no teacher dashboard to set up, no roster to import, and no PIN code to distribute. Hand students the link, they play. Progress saves to LocalStorage on the specific device — enough for the most common classroom shape (kids return to the same Chromebook each day).

03 How does this compare to TPT, Boom Cards, or IXL Classroom?

TPT and Boom Cards are marketplaces of teacher-made decks; we are a publisher with one consistent K-6 curriculum aligned to the Common Core. IXL Classroom has assignment workflows and parent reporting we do not (yet) have; the trade-off is IXL is $79+/year per family while we are free. Honest fit: same-day classroom resource with zero account overhead.

04 Can I embed individual games in my classroom website?

Yes. Every Fun Math manipulative ships with a one-click "Embed on your site" button that copies an iframe snippet. Drop it into Google Sites, Canvas, Schoology, Seesaw, WordPress, Notion, or any HTML-accepting LMS. See the [virtual manipulatives hub](/manipulatives/) for the full list of embeddable tools.

05 Will it work on our school Chromebooks behind GoGuardian / Lightspeed / Securly?

In almost every case, yes. We are a vanilla HTTPS web app — no extension, no Flash, no plugin — and content filters classify us as "education" by default. If your filter is unusually strict, ask IT to allowlist inquiryai.zogmath.com. Full IT details on the [Chromebook compatibility page](/chromebook/).

06 Is everything actually CCSS-aligned, or is that a marketing claim?

Every grade has a metadata file listing the CCSS codes covered (3.OA.A.1, 3.NF.A.1, etc.), every topic page surfaces those codes, and the [Common Core Review Games hub](/common-core-review-games/) lets you browse by standard. The alignment is in the JSON-LD schema too, so accessibility tools and standards-based grading systems can read it.

07 What about students with IEPs / 504s / English learners?

Two design choices help: (1) every problem starts with a visual model — no language-heavy word problems gate the math; (2) Socratic hints escalate slowly, so students with processing-speed accommodations are not penalized by a timer. We do not have specific dyslexia / ADHD-tagged content yet, but the visual-first design and zero-pressure pacing is friendly to most cognitive profiles.

08 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.

09 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.
