remediation and enrichment

I've started helping at the new school, a creative school that gets the best results out of children, e.g. making music instruments from both professional (strings, plectrum) and waste material. What I'm doing is mindmapping with number theory and the result after one half hour is that all four children didn't want me to stop after half an hour. It remediates language, maths skills, creative thinking and memory at the same time. I can recommend it as enrichment, motivator, remediation and attention training at the same time in education. It seems to work. After I did a remediating math crossword puzzle and the attention of the children was very good. Of course it's fun to also include some history or funny examples.
