Story: While at Harvard, I applied to 8 school districts in the Chicago area for employment: the Chicago Public Schools, Evanston, Glenbrook, New Trier, Niles, Highland Park-Deerfield, Oak Park-River Forest, and the University of Chicago Laboratory Schools. I received five offers and so much liked my student teaching experience at Niles under Jim Martin that I accepted that offer.

1966-1967, University of Michigan Laboratory School – 8th grade mathematics

1967-1968, University of Michigan Laboratory School – geometry – writing Geometry – A Transformation Approach (GATA) with Art Coxford

1968-1969, Adrian H.S., Adrian MI – geometry honors – teaching GATA, trying out ideas for a 2nd-year algebra when students are familiar with transformations – department head, Pete Boudreau
