About States of Matter at Upper KS2
At Upper KS2, children aged 9–11 are ready to tackle States of Matter with confidence. Dailulu's daily tests use short, focused sessions — just a few minutes a day — to build fluency and retention over time. Rather than cramming, consistent daily practice is the most effective way for children to master States of Matter.
Every question on Dailulu is checked, calibrated for age, and rotated daily so children never see the same test twice. Parents can track streaks and scores from the dashboard.
