What is happening here?
Reading an analog clock asks for several things at once: knowing the difference between the long and the short hand, reading the numbers up to 12 in a circle, and understanding what "quarter past" or "half past" means. For many children this takes time.
What helps at home
Talk about the time out loud in everyday life: "It is just after half past seven, we have to leave in 20 minutes." The child hears the language of time and links it to real situations.
Practice only the full hours first, then half hours, and only then "quarter past" and "quarter to". Small steps avoid overwhelming them.
Materials
A learning clock with movable hands works well. Let your child set the times you call out themselves. The reverse way, where you set a time and the child reads it off, is only the second step.
