Decimal Drop: Decimals Game for Grades 4‑6
Steer falling crates into the right place-value lane before they land.
Numbered crates fall toward a row of lanes. Slide each crate into the correct lane (a place-value name, a number-line section, a comparison symbol, a rounded value or a sum) and drop it before time runs out. Five correct crates clear a row. Covers tenths, hundredths and thousandths, comparing, rounding and adding decimals.

What kids practise
Decimal Drop gives students repeated, low-pressure practice with decimals, place value, comparing decimals, rounding decimals, adding decimals, and number line. It is written for grades 4-6, with levels that let younger and older players start at the right difficulty. Every question is generated fresh, so a replay is never the same, and a wrong answer shows the correct one so the round teaches as well as tests.
How it plays
Controls: Left/Right arrows (or A/D, or keys 1-5) pick a lane. Down arrow or Space drops the crate. P pauses, M mutes. On touch: tap a lane to move, tap it again or press Drop to drop.
It works with a keyboard, a trackpad or a touch screen, so it runs on school Chromebooks, tablets and phones.
