Lee proposes to replace the Seguin Teens Board with a tray containing numeral cards, written numbers and plastic 10-base decimal counters. He says, “The layout for this new material is similar to the old Seguin Teens Board, except that the numerals are placed two on a card, instead of five on each wooden board as before. This new design is more uniform and compact, allowing children to easily carry the entire set of materials from the shelf to the work-space in a single tray. In format, this follows closely such protocols as take out everything and enhance independence”.

The new place value math work also includes written words to match each number as well. For example, the word “eleven” matches with the “11” numeral and its respective quantity of one plastic ten rod and unit. Lee says, “Field tests with these materials at the New Way School show that children use them precisely as intended, with very good results”.

Lee is also designing other math materials using the same compact, uniform approach. He says, “These new designs provide more order, clarity, and economy of space in the presentation of various math concepts to children. Hopefully, others may find them useful as well, once they are more fully developed and field tested at the New Way School.”
