Equivalent Fractions
Different fractions naming the same amount (1/2 = 3/6); find/recognize equivalents via models + multiplying/dividing num & denom.
Practice / Learn →Comparing Fractions
Compare fractions — same denominator (more parts = bigger), and using benchmarks/common size; >, <, =.
Practice / Learn →Adding Fractions with the Same Denominator
Add (and subtract) fractions with like denominators — add numerators, keep the denominator.
Practice / Learn →Adding Fractions with Unlike Denominators
Find a common denominator (a "common floor"), rewrite, then add — incl. least common denominator.
Practice / Learn →Multiplying Fractions
Multiply two fractions (a/b × c/d = ac/bd) via the area/overlap model; "a part of a part."
Practice / Learn →Mixed Numbers & Improper Fractions
Convert between improper fractions and mixed numbers (wholes + leftover parts).
Practice / Learn →Ratios — Part-to-Part Sharing
Ratios as part-to-part comparisons; split a total by a ratio (e.g. 1:1 of 10 = 5 and 5).
Practice / Learn →Scaling Recipes & Ratios — Proportions
Scale a ratio/recipe by a factor (4→12 people = ×3; multiply each part); proportional reasoning.
