While attending the Seminar of the Norwegian Storyline Network in Vestfold College of Education recently I met Arvid Undebakke, the managing director of a company called Percolo A/S. He showed me a new building material which he has designed withillustrations of how it had been used together with Storyline. Arvid explained: “The notches on the blocks also fit together mathematically. Two blocks with 3 notches make 1 block with 6 notches. In this way, mathematics is practiced on both a practical and theoretical level. This, in turn, helps a child’s understanding of mathematics. Two Storyline booklets written by Merethe Fagernaes have also been produced called “The Viking Farm” and “The Loghouse Village”. Percolo Playwood is used in both Storylines where mathematics is the leading subject for Ages 6-13.” Visualisation plays and important part in the methodology and it is obvious that this material is yet another creative option for teachers.
