Reflection: Connection to Prior Knowledge Common Denominator Comparison - Section 3: Student Practice


During this conference, Doubling & Halving, I encouraged a student to rely on her understanding of doubling and halving (from a prior lesson during our addition and subtraction unit) to find equivalent fractions and fractions with common denominators. It is clear how important it is to continue building a solid understanding of number sense and fact fluency throughout a fraction unit.
