• ### Activity 1 / Addition and Subtraction: Equations Worksheet

One of the most common number equation solving mistakes young mathematicians make is not using the correct order of operations when solving equations. This cheery worksheet will give your child plenty of practice solving addition and subtraction problems using colorful pictures for one-to-one representation. They'll strengthen their visual processing skills as well as they decide whether they add or subtract, and use the traceable lines to identify the correct equation.

• ### Activity 2 / Drawing to Help Us Subtract Worksheet

Math is meaningful when it involves different solution strategies. This free worksheet uses engaging Arctic animal images to offer one-to-one representation for your child to solve basic subtraction word problems. They'll read the problem and then use the colorful pictures of the Arctic animals to decide which drawing represents the correct solution. They'll have so much fun with their new frosty friends, they won't even know they're practicing math!

• ### Activity 3 / Adding and Subtracting: Instruments Worksheet

This fun worksheet lets children help their friend Isla as she counts the musical instruments she has. The downloadable PDF will have them add or subtract with Isla, using the pictures for one-to-one number representation, and then using the traceable lines, they'll connect the pictures to the correct addition or subtraction equations. It's a fun and easy way for them to work on differentiating between orders of operations too!

Great for kids
Our 7 years old daughter loves reading activities and every off-line game Kids Academy offers. This is a very good app, I highly recommend it!

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.
