What does "Check" mean on day 3 Spelling?

Day 3 of Week 1 of your Language Arts guide provides the following:

Make up a sentence or two with any misspelled words yesterday. Have your children write the sentence(s). Check for accuracy. If the spelling words were misspelled, then have them rewrite them again, accurately, five times each. If your children didn't miss any words yesterday, see if you can come up with "silly sentences" that include as many of the week's words as possible. Have them write these sentences.
