Abstract
A program that allows students to explore concepts of numeration and the operations of addition, subtraction, multiplication, and division in either of two representational systems for whole numbers and decimals (on Dienes’ blocks or on digits of numerals) and which reflects the student’s actions in the other representational system. Students can work in any base from two to ten.
