Step into a shadowy tomb and sort glowing inscriptions into complete sentences, fragments, and run-ons. On harder chambers, forge broken lines into real sentences. Built for fourth and fifth graders who already know the basics and want a tougher grammar quest.
Pick a Mode and Difficulty
Choose Timed (75 seconds) or Survival (3 lives). Easy is complete vs fragment; Medium adds run-ons; Hard also asks you to finish broken sentences.
Read the Tablet
A carved inscription appears. Decide whether it is a complete sentence, a fragment, or two thoughts jammed together.
Drop It in a Jar
Tap a relic jar or drag the tablet onto it. On forge rounds, tap the ending that makes a real sentence.
Open the Next Chamber
Eight correct sorts light the vault seals. Keep going to raise your score before time or torches run out.
Tomb Vault Sorting
Drag or tap each inscription into a relic jar: Complete Sentence, Fragment, or Run-on. Instant gold-seal feedback tells you if the vault accepts the tablet.
Forge Broken Lines
Hard mode adds complete-the-sentence puzzles. Choose the shard that turns a dependent clause or bare subject into a full sentence.
Three Expedition Levels
Easy sorts complete vs fragment. Medium adds run-ons. Hard mixes trickier 5th-grade lines with sentence-forging challenges.
Seals, Chambers, and Streaks
Eight seals open a chamber. A 75-second timed run or a 3-torch survival trek tracks score, accuracy, and your best haul.
Inscription Vault is a fourth- and fifth-grade grammar adventure. Players read short tomb-themed lines and sort them as complete sentences, sentence fragments, or run-on sentences. A complete sentence has a subject and a predicate and can stand alone. A fragment is missing a complete thought. A run-on smashes two complete thoughts together without the right punctuation or a linking word. Harder chambers also ask players to finish a broken line so it becomes a complete sentence.
Steps Up After the Basics
Kids who can already spot easy sentences get a tougher mix: longer fragments, sneaky run-ons, and lines that need a finishing shard.
Built for Grades 4–5
The reading level and sentence types match upper-elementary writing, when students start producing more complex text.
Instant Grammar Feedback
A miss lights the correct jar and explains why — missing subject or predicate, two jammed thoughts, or an ending that still is not a sentence.
Replayable Expedition
Inscriptions shuffle every run. Timed and survival modes plus three difficulties keep practice from feeling like a worksheet.
A complete sentence has a subject (who or what) and a predicate (what happens) and expresses a full thought, such as “The bronze door groaned open.”
A fragment looks like a sentence but cannot stand alone. It may be only a phrase (“After the long climb.”) or a dependent clause (“Because the door was locked.”).
A run-on joins two complete thoughts without a period, semicolon, or conjunction — for example, “The torch flickered the shadows jumped.”
It is written for fourth and fifth graders. Easy works as review; Medium and Hard push students who already practiced complete sentences vs fragments.
No. Tap a jar, or press 1, 2, or 3. Drag-and-drop is optional and works on touch screens.
Yes. The grammar practice is English. Buttons and labels follow your site language, but the tablets stay in English so the skill stays authentic.
