Finally — Multiplication Practice for the 13s, 14s, and 15s.
If your child already knows the standard multiplication tables but needs practice beyond 12×12, you've probably discovered the same problem we did: almost every workbook, worksheet, and app stops at the 12s. Yet many advanced students are expected to master multiplication facts through 15×15. This workbook was created specifically to fill that gap with focused practice on the 13s, 14s, and 15s.
Why most multiplication resources stop at the 12s
Standard multiplication practice was built around the 12×12 table, so resources for multiplication facts beyond 12 can be surprisingly hard to find. Yet many students are expected to master multiplication through 15×15. Homeschool families—including many using Classical Conversations—often discover that once their child reaches the 13s, 14s, and 15s, the practice materials simply disappear. If you've been hunting for a workbook that picks up where the standard multiplication tables end, you're in the right place.
Why Most Multiplication Workbooks Fall Short
| Most Multiplication Workbooks | Nailed It! Math |
|---|---|
| Stop at 12×12 | Covers 13s, 14s & 15s |
| Assume students are done after the standard tables | Helps students master multiplication facts beyond 12 |
| Answer key only in the back of the book | Includes digital, printable, and in-book answer keys |
| Requires constant page flipping while grading | Check answers instantly from your phone |
| Long review sections | One focused page per day |
| Generic practice | Specifically targets the 13s, 14s, and 15s |
As homeschool parents, we designed this workbook around the frustrations we actually experience. Instead of constantly flipping to the back of the book, parents can use the answer key however they prefer: pull it up on a phone, print a separate grading copy, or use the traditional answer key included in the workbook. It's a small change that saves time every single day.
How to help your child master the 13s, 14s, and 15s
You don't need a new method — just consistency and a couple of patterns that make these tables far less intimidating.
Lean on what they already know. Each of these tables can be broken into facts your child has already mastered:
- 13 × n = (10 × n) + (3 × n). So 13 × 6 = 60 + 18 = 78.
- 14 × n = double the 7s. Since 14 is 7 twice, 14 × 6 = (7 × 6) doubled = 42 + 42 = 84.
- 15 × n = (10 × n) plus half of that. Because 5 × n is half of 10 × n, just take ten times the number and add half. So 15 × 6 = 60 + 30 = 90.
Keep practice short and daily. Five focused minutes a day beats a marathon session once a week. Spaced repetition is how facts move into long-term memory, which is exactly why a single page a day works so well.
Skip-count out loud. Counting by 13s, 14s, and 15s — in the car, on a walk — builds the same fluency from a different angle and breaks up the drilling.
Mix it up once the basics stick. Once your child can recite a table, switch to out-of-order and mixed-table problems so they're recalling facts, not reciting a song.

This workbook is intentionally focused on the 13s, 14s, and 15s. It's ideal for families who already have materials covering the standard multiplication tables and simply need help going beyond 12×12.
If you're looking for complete multiplication practice from the beginning, we're also creating a full multiplication workbook that covers every table from 1×1 through 15×15.

Nailed It! Learning started at our own kitchen table. We're a Classical Conversations family with three kids in Foundations — one of them also in Essentials — and like a lot of CC parents, we kept hitting the same wall: our kids needed to master the 13s, 14s, and 15s, but every workbook and app we found stopped at the 12s. So we built the practice we wished existed. Everything we make is the kind of clean, low-prep, open-and-go material we actually want to use with our own children. We're not a big publisher — we're parents in the same season you are.

Frequently asked questions
Why do Classical Conversations students learn the 13s, 14s, and 15s?
Classical Conversations Foundations students memorize the multiplication tables from 1×1 through 15×15 as part of their math memory work, and that work repeats every year — so practice through the 15s is a recurring need for CC families. (We’re an independent resource and aren’t affiliated with Classical Conversations.)
What's the easiest way to memorize the 15 times table?
Take ten times the number and add half of it. For 15 × 8, that’s 80 + 40 = 120. The "half of ten-times" trick makes the 15s one of the easier "hard" tables.
Is there a trick for the 14 times table?
Yes — the 14s are just the 7s doubled. If your child knows 7 × 9 = 63, then 14 × 9 is simply 63 + 63 = 126.
At what age should kids learn multiplication beyond the 12s?
It varies, but children typically tackle the 13s–15s once they’re fluent with the 0–12 tables, often around ages 8–11. Mastery of the lower tables matters more than age.
How long does it take to master the 13s, 14s, and 15s?
With five focused minutes of practice a day, many children build solid recall within a few weeks. Daily consistency matters far more than long sessions.
Who is this workbook for?
Any student moving beyond the standard 0–12 multiplication facts — including Classical Conversations Foundations families, classical and mastery-based homeschoolers, and any child working toward the 13–20 tables or who has simply outgrown ordinary times-table practice.
Does this work with curricula other than Classical Conversations?
Yes. It’s program-agnostic practice for any approach that takes multiplication past the 12s, so it slots in alongside whatever math program you’re already using.
What if my child needs the tables all the way to 20?
These books build solid fluency through the 15s, which is a strong foundation toward the full 1–20 range that many advanced and international programs expect.
