# Math Lesson - Introduction to Arrays, Grade 2

• ### Activity 2 / What's an Array? Worksheet

Before beginning this exercise, you must first explain to your children what an array is. Use this worksheet to teach them that an array is a group of objects, pictures, or numbers in columns and rows. A rectangular array is a group of objects that are arranged in equal rows and columns. Make sure your child understands and remembers this. Then, ask your child to look at the pictures in the printout and see if they can point out any that show rectangular arrays. Help them check the pictures.

• ### Activity 3 / Fruity Array Quest Worksheet

This worksheet requires that your child know the meanings of the words, “rows” and “columns”. If they do not, you must first explain to them what they are. Rows are objects that are arranged in a horizontal position. Columns, on the other hand, are arranged in straight lines. In the picture, there are arrows showing the directions the objects are facing. Armed with this knowledge, your kids should be able to easily answer the questions in this printout. Help them check the fruit arrays that match the descriptions.

• ### Activity 4 / Independence Day Arrays: Rows and Columns Worksheet

When is Independence Day? Does your child know? Maybe they are particularly fond of the holidays and look forward to the family picnics and fireworks. Or, they don’t yet understand the importance of the holiday yet. Whichever way, after this worksheet exercise, your little ones will be much more familiar with the holiday. Help your kids look through the pictures in the printout and check the correct number of rows and columns in each array.

• ### Activity 5 / Representing Arrays with Number Sentences Worksheet

An array is a group of objects, pictures, or numbers in columns and rows. An array can be interpreted in two ways, and you can teach your kids those two ways with this colorful, fun worksheet. First, you can represent an array in terms of rows as shown in the picture. Secondly, you can represent an array in terms of columns, also shown in the picture. Now, help your student draw a line to find the bee’s way to its beehive which shows the correct number sentence.

Daughter's favorite
Still a top favorite for our 7 year old. She loves earning her stars as she learns to trace letters and numbers. Coloring and the sounds are engaging and are on target for her age group and being Pre K.
