When our DS started primary, the school invited parents to help; I did one day a week supporting reading with Yr1, Yr2, for five years. Once I felt confident, I also did Yr6 gardening activities Friday afternoons, and ran an after-school keyboard club with Yr6.
Got a job as TA at an infant school, for ten years; worked mainly Yr1, Yr2, but also Nursery and Reception. Had a lunchtime recorder group for ten years; coached Yr2 on percussion to accompany the Christmas production each year; did computer and touch typing activities; trained other TAs on computers (twenty years ago, when computers were less common to most people.)
Then two years as TA in a tough comprehensive.
Retired, but continued voluntary work in primary and secondary. One of my very first 'readers' turned up again seventeen years later, on her final year of Teacher Training; our roles were reversed, as SHE needed to direct ME in the classroom! She is now a successful teacher.
