A dawn canal lock, a wooden barge, and a verb painted on the canvas. Read the English sentence. Steer into letter crates to add letters, or graze the iron comb to strip one, until the verb agrees. A true form opens the lock. A mismatch slams the gates.
Pick a Lock
Arcade is ten hauls. Survival is three lives. Easy, Medium, and Hard change how many letter edits sit on the water.
Read the Plaque
The English sentence has a blank. The barge canvas shows the current verb. Decide if you need to add or strip letters.
Steer and Hit
Tap Raise or Lower, tap a lane, or use the arrow keys. Hit the crates you need. Dodge the decoys. The gates check the verb.
Chase the Best
Streaks add bonus points. A clean arcade run adds a perfect bonus. Beat your best on each mode and difficulty.
Steer the Sluice
Three water lanes sit in a brick lock. Raise or lower the barge to hit a crate or an iron comb.
Letters Change the Verb
A crate stamps a letter onto the canvas. A comb scrapes the last letter off. The sentence stays on the iron plaque above the water.
The Gate Judges
Reach the lock doors with a verb that agrees. A true form opens the gates and scores. A wrong form slams them.
Score That Moves
Useful hits pop +50. A clean lock awards hundreds plus a streak bonus. A labeled Score plate and a saved best stay on the chamber.
Lock Haul is a subject-verb agreement game. A wooden barge carries a verb through a dawn canal lock. The player steers among three sluice lanes to hit letter crates or iron combs, adding or stripping letters until the verb agrees with the subject. Correct forms open the lock gates. Wrong forms slam them. The goal is to finish the haul with a high score.
Agreement You Can Haul
Students change the verb on the barge instead of tapping a worksheet choice. The lock only opens when the form fits.
Sentences Stay English
Practice lines stay in English so the grammar examples stay intact. Buttons and labels follow the site locale.
Fast Feedback
A useful crate pops points. A slam resets the streak and shows the needed verb.
Touch First
Raise and Lower sit under the lock. Lanes are large enough to tap on a tablet.
Subject-verb agreement. Easy is add or drop -s. Medium adds -es, has/have, is/are, and do/does. Hard mixes compound subjects, indefinite pronouns, and was/were.
No. The practice sentences stay in English. Buttons, hints, and score labels follow the site locale.
The verb on the canvas changes the wrong way and the barge rocks. You can still try to fix it before the gates. A wrong form at the lock slams the doors. In Survival you lose a life.
How many letter edits sit on the water and how fast the current runs. Easy is one change, such as sit and sits. Hard uses longer hauls such as have to has.
Fourth through sixth grade, when students practice subject-verb agreement. Stay on Easy if adding or dropping -s is still new.
