Aanya and two others — comparing by the top number only

Aanya, Veer, Mira

The rest are ordering three fractions well and are ready to slot a fourth one in.

Instruction

Same bottom, then compare

Whole class: turn 3/4 and 2/3 into twelfths, then compare. Show why you cannot trust the top number alone.

Builds straight on Tuesday's equal-fractions lesson, so it should feel familiar.

10min

1:1 Talk-buddy

Bigger or smaller, and why

Pairs sort six fraction cards into bigger-than-half and smaller-than-half, saying the reason each time.

Half is a friendly anchor; it catches the 'top number only' mix-up fast.

20min

Self-work

Order the fraction sets

Three levels of ordering sheets by name. Pull Aanya, Veer and Mira to a quick same-bottom drill.

Support sheet keeps the bottoms small (halves, quarters, eighths) on purpose.

10min

Activity

Human number line

Six children hold fraction cards and arrange themselves smallest to largest at the front. The class checks.

Movement close; no materials beyond the printed cards.

Every section lets you accept, edit, or reject. You decide. The AI does the checking work, never the teaching.
