Charles Ledger’s Descartes Medal citation sums up his unique approach to mathematics education: “Charles is an advocate of teaching methods somewhat at variance with current trends – using intensive drill and pressure-cooking problem solving.”  He is the creator and principal of Spirit of Math Schools in Toronto – a program for junior high school students which has proved both popular and successful in helping younger students tackle mathematics.
Charles taught at Beverley Heights Jr. H.S. and Zion Heights Jr. H.S. in North York, the Academy for Gifted Children in Richmond Hill, Bishop Tucker Theological College in Uganda, as well as two teacher training schools in that country.
His own education included elementary and high school in Winnipeg, the University of Manitoba, Wycliffe College at the University of Toronto, Union Seminary in New York, and teachers college at Columbia University.
Charles maintains a close affiliation with the Anglican Church and is involved in many aspects of church life.
