Being fluent means you do not stop to count on fingers or skip-count from the start. You just know the answer, fast. Aim to answer facts like 6 × 8 or 56 ÷ 8 in under three seconds. *(drawing: See it, do not count it: 7 × 9 = 63.)* **Example.** Mia forgets 9 × 7 for a second. She knows 10 × 7 = 70. Since 9 is one less than 10, she takes away one 7: 70 − 7 = 63. So 9 × 7 = 63, without counting from zero. **Tip.** Every multiplication fact comes with two division facts for free. If you know 8 × 6 = 48, you also know 48 ÷ 8 = 6 and 48 ÷ 6 = 8. Learn one fact, get three. **Recap.** Fast recall or a quick known-fact trick both count as fluent. Either way, you get to the answer in seconds. ## Practice 20 questions on this page, each with its working shown. ## Needs first - [Division as Unknown Factor](https://lightmysky.com/learn/mathematics/division-as-unknown-factor-mt_GDG9_SZmsO) - [Times tables (age 7+)](https://lightmysky.com/learn/mathematics/times-tables-age-7-mt_wQ89AEXhz3) ## Opens up - [Multiplying by Tens](https://lightmysky.com/learn/mathematics/multiplying-by-tens-mt_isojCL9yy-) - [Short division](https://lightmysky.com/learn/mathematics/short-division-mt_MCu_SNg_OW) - [Patterns in addition and multiplication tables](https://lightmysky.com/learn/mathematics/patterns-in-addition-and-multiplication-tables-mt_w6MxaaoMXZ) - [Unknown in Multiplication & Division](https://lightmysky.com/learn/mathematics/unknown-in-multiplication-and-division-mt_xZvDCYA5Ae)
