John Evans on 13 Aug 16"It's no secret that fractions are a very difficult concept for students to understand. But why is that? fractions are an extremely abstract concept, and without adequate concrete and representational experiences, students do not develop mental images of what the abstract symbols mean. In Texas, students begin formal fraction instruction in 2nd grade under our newly adopted TEKS, but the symbolic notation for fractions (1/4, 2/3, etc.) is not taught until 3rd grade. The 2nd grade standards include: partition objects into equal parts and name the parts, including halves, fourths, and eighths, using words explain that the more fractional parts used to make a whole, the smaller the part; and the fewer the fractional parts, the larger the part use concrete models to count fractional parts beyond one whole using words and recognize how many parts it takes to equal one whole Let's take a closer look at each."
