Document Summary
You should have achieved the following learning outcomes: --identify the "big ideas" associated with learning fraction concepts. --distinguish between the different models for representing fractions and name their affordances. --solve challenging tasks related to different fraction representations. --engage in fraction activities and be able to identify how they support the development of the fraction "big ideas" --identify difficulties and misconceptions held by students about fractions. Van de walle et al (2013) presents a number of big ideas" for developing fraction concepts that are also referred to in the lecture and readings: --fractions must be experienced across different constructs, including fractions as part of a whole, fractions as measurements, fractions as division, and fractions as ratios. --there are categories of models for representing and working with fractions, such as area, length and set models (helen chick"s lecture particularly focuses on this)
