Teacher tip
Project this page and tap Full screen. Tap a brick to shade from the left edge through that brick — the first half is 1/2, the third fourth is 3/4. Leave Equivalents on and tap 1/2, then 2/4, then 3/6; matching lengths are marked together. Compare sets two fractions and shows which bar is longer. Challenge asks for the same length on another row, such as a different way to show 3/4. One idea fits in five minutes.
Nothing selected. Tap a brick to shade that fraction from the left of its row.
Arrows move between bricks. Enter selects. Escape clears.
