Fraction Framework: Visual Walkthrough

Section role: Supports the 'Building the Fraction Framework' section while the teacher formalizes concepts. Slides: (1) Title – 'Understanding Fractions'; (2) Unit Fractions and Decomposition – bullets: 3/8 as 1/8 + 1/8 + 1/8, definition of unit fraction, visual model of a chocolate bar divided into eight parts with three shaded; (3) Equivalent Fractions Visually – bullets: what happens when we multiply numerator and denominator by 'n', visual model showing 1/2 is the same as 2/4 (a rectangle divided into two, then re-divided into four); (4) Adding Tenths and Hundredths – bullets: why 3/10 becomes 30/100, example of adding 3/10 + 5/100 using a grid model; (5) Dividing by Unit Fractions – bullets: 2 divided by 1/2 as 'how many halves in two wholes', visual model of two whole circles divided into halves; (6) Summary – bullets: fractions are built from unit fractions, equivalent fractions represent the same value, operations require common denominators for addition. Concrete examples: 1/8, 3/8, 1/2, 2/4, 3/10, 30/100, 5/100, 2 divided by 1/2. Hooks back to the 'Great Fraction Trek' challenge by formalizing the discoveries made. Sets up the 'Fraction Proficiency Check' by reviewing foundational concepts. Closing slide: 'What is the most important idea about fractions you learned today?' — prompts student reflection.
