What should you review before the quiz?
Reread the key facts of the lesson and the worked example. If a question is hard, go back to the matching part of the lesson, then try the quiz again. Write your work on scrap paper: most mistakes come from skipping a step, not from the idea itself.
Remember:
Rows go across and columns go up and down.
Every row in an array has the same number of objects.
A repeated addition equation adds the same number once for each row.
Adding rows and adding columns give the same total.
Second grade arrays have up to 5 rows and 5 columns.
