Speed 20 Mental Arithmetic Plan
Speed 20 is the recommended daily routine for most learners. A 20-question session is long enough to establish rhythm and track improvement, but short enough to fit into any schedule—usually 2 to 5 minutes depending on difficulty. This plan balances speed and accuracy: you aim for consistent pacing with fewer pauses, and your goal is to maintain accuracy while gradually reducing your total time. Use Speed 20 for 2-digit addition and subtraction, multiplication tables, or any skill where you want to build fluency without the endurance challenge of longer sets. Track your time and try to beat it by small margins each week.
How to Use This Plan
- 1Choose your operation and digit level. Speed 20 works best with 2-digit addition/subtraction or times tables. If you’re comfortable with Daily 10, this is your next step.
- 2Complete the set with consistent rhythm. Don’t rush—aim for fewer pauses. Your goal is steady pacing with high accuracy (18-20 correct).
- 3Track your time and repeat daily. Write down your time and accuracy. Each week, try to shave off 10-20 seconds while maintaining correctness.

Common Questions
Why is Speed 20 recommended?
It’s the sweet spot: long enough to build fluency, short enough to stay focused. Most learners see steady improvement with daily Speed 20 practice.
What’s a good target time?
For 2-digit addition, aim for 2-3 minutes. For times tables, 1-2 minutes. Your first session establishes your baseline—improvement comes with repetition.
Should I prioritize speed or accuracy?
Accuracy first, always. Aim for 18-20 correct. Once you hit that consistently, speed will naturally improve. Rushing causes mistakes and builds bad habits.
