\n 30-minute plan\n

5 min — learn the idea

5 min — study examples

18 min — practise questions

2 min — check mistakes

\n \n Do one question at a time. Don’t aim to finish fast. Aim to get the next step right.\n \n

\n Parent / teacher note\n

\n This lesson uses short chunks, immediate feedback, retry options, and worked steps after mistakes. That structure usually works better for learners who lose focus when the page feels too crowded or when the correction comes too late.\n
