Direct linkYun, Jeong Oak; Flores, Alfinio – Mathematics Teaching in the Middle School, 2012
Students can use geometric representations of numbers as a way to explore algebraic ideas. With the help of these representations, students can think about the relations among the numbers, express them using their own words, and represent them with letters. The activities discussed here can stimulate students to try to find various ways of solving…
