# Math Lesson - Addition with Arrays - Part 1, Grade 2

• ### Activity 2 / Arrays and Equations 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, an array can be represented in terms of rows, as shown in the picture. That is, 3 rows in 4 places make 12. Or, an array can be represented in terms of columns, as also shown in the picture. For example, 4 columns in 3 places make 12. Note that both cases always amount to the same sum. Now, help your child trace on the dotted lines from the number sentences to the cars that match.

• ### Activity 3 / Schoolbag Arrays Worksheet

An array can be represented in terms of rows or columns. Can your child easily differentiate between rows and columns? You can use this simple worksheet to see how well they understand the concept of arrays. In this printout, your child’s task is simple enough – check all the arrays that match the equation 5+5+5=15. Help your child count the objects in each group. Then, ask them which arrays have 15 objects in them. Tell them to check the boxes underneath the correct arrays.

• ### Activity 4 / Easter Arrays Worksheet

How much does your child look forward to the Easter holidays? Do they enjoy the activities and traditions that come up during the holiday? Perhaps they are especially fond of the Easter bunny and the Easter egg hunts. If they are, they would get a good kick out of this worksheet exercise. Look through the page with your child. Help them check the 2 equations for each array. Then, circle the correct sum.

Great app!
This app is wonderful for my 7 years old son! :) It focuses on basic reading, writing, and math skills. The reward system is great and consistent!

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.

This was a really fun way to get my kids to practice their math. I usually struggle to get them into it and Kids Academy makes it easy.
