One of the things that can make learning grammar challenging is not having enough sentences with which to practice. Constructor uses a database of hundreds of sentence structures that can generate millions of unique sentences based on the control options that are set. For example, the sentences may use different subjects, different tenses of verbs, different phrases or clauses, or may be reworded in the form of a question or an imperative sentence. Because of this, players have a nearly unlimited number of sentences on which to practice. And because they may never see the exact same sentence twice, they must answer the questions based on their knowledge of grammar rather than on their memory of having seen the same sentence before.

Identifying the parts of a sentence is like putting together the pieces of a puzzle and so Constructor allows you to play two games in one. First, players answer grammar questions to identify the elements of a sentence and for each correct answer, they win a puzzle piece. When they have acquired enough pieces, they get the chance to solve a puzzle with those pieces. The puzzle in each round gets a bit more challenging and requires more pieces to solve. Can you become a "Grammar Guru" by solving all fifteen puzzles?

Game Plans

• Game Plans are used to control the options for each game.
• Over 55 sentence options determine the types of sentences that are generated.
• Nearly 60 question types control the types of questions that are asked about the sentences.
• If the optional items question type is set, not only does the player have to identify the various elements, but must first also determine if an element exists in the sentence or not.

Game Play

• Constructor presents a sentence and asks various questions about that sentence.
• Players earn puzzle pieces for each correctly answered question.
• Extensive help is available at any time by tapping on the question icon.
• A maximum number of questions are allowed for each round. With those questions, players must win enough pieces to solve the puzzle for that round.

Solving the Puzzle

• Drag puzzle pieces into place to complete the puzzle.
• Pieces may not overlap and must be completely contained within the puzzle.
• If a player needs more pieces, he or she can continue to answer additional questions and possibly earn additional pieces.

Track Answers

• Constructor tracks each of a player's answers so they can later see how they are doing in particular areas.
• Track the answers for up to eight players.
