An array is objects, pix, or numbers organized in rows and columns. Show kids two ways to interpret this: 3 rows in 4 places = 12 and 4 columns in 3 places = 12. Help your child trace the number sentences to the matching cars. All equations always add up to the same amount.
Explain to your child that an array is a group of objects, pictures, or numbers in columns and rows. Show them a rectangular array is a group of objects in equal rows and columns. Guide them to check the pictures in the worksheet to spot any rectangular arrays. Help them remember this concept.
