Performance Drivers
Age 11 13 typically need to emphasize:
- Introducing memory strategies
- Academic test preparation support
Benchmarks & Interpretation
Compare your number memory scores against cohort averages to spot strengths or risks. Track both best-case and consistency metrics to ensure progress translates into competition.
Lifestyle Levers
Off-game habits move the needle. Start with these levers:
- Sleep schedule consistency
- Managing screen time
- Extracurricular balance
Training Playbook
Run focused BrainGames blocks 3-4 times per week. Pair drills with immediate application—scrims, study, or high-stakes work—to lock in gains.
- Chunking introduction (groups of 3-4)
- Competitive memory games with peers
Integration & Review
Review metrics weekly with teammates or coaches. Tag lifestyle variables (sleep, travel, caffeine) so you can correlate them with performance swings.
