About Word Lab
Vocabulary work that goes past definitions: pick the synonym, flip to the antonym, choose the word that fits the sentence.
Ankhdase tracks 2 distinct skills in Word Lab, including Vocabulary and Synonyms & antonyms. Because mastery is estimated per skill rather than per game, the questions shift toward whatever a student is getting wrong — and away from what they have already proved they know.
How to play
- Read the word or sentence and pick the best match.
- Watch the instruction — sometimes it wants the opposite, not the synonym.
- Tap 🔊 to hear a word read aloud.
Skills Word Lab practices
- Vocabulary
- Synonyms & antonyms
Mastery is estimated separately for each of these, which is what lets the difficulty move independently — a student can be fluent on one and still be fed easier questions on another.
