Fractions That Finally Make Sense

For grades 4–8, or anyone who never really got fractions. Every chapter follows the same path: a real mistake → why it happens → a picture that fixes it → practice that changes the situation → a re-check.

What's inside (draft outline)

Start here

15-question diagnostic with an answer map

Part 1 · What a fraction really is

"Equal parts" and why the whole matters · Bigger denominator, bigger fraction? · Equivalent fractions

Part 2 · Operations without memorized rules

Why 1/2 + 1/3 isn't 2/5 · Mixed numbers · Does multiplying always make bigger? · Why "flip and multiply" works

Part 3 · Fractions in word problems

"A fraction of what?" — finding the whole with bar models · "1/3 of the rest": multi-step problems

Part 4 · Bridge to ratios, percents and equations

Fractions ↔ decimals ↔ percents · Part-to-part vs part-to-whole · Percent of what? · From a bar model to x
