The Sentence Factory · Grades 1-8

Our town's #1 export: complete sentences.

The characters work the stations; the Mayor inspects every finished sentence. Learn a concept, quiz it, build it, and earn your certificate.

    Put it to work until it sticks.

  4. 4 Create

    Use it in the student's own writing.

  5. 5 Certified

    The character signs off on what was earned.

No lesson, just the machines
