• ### Activity 1 / Missing Number: Ferris Wheel Math Worksheet

Go up and down, and round and round while completing this exciting addition worksheet from Kids Academy! Hop on the Ferris wheel and complete each equation found in the baskets, solving for the missing number! Is the missing number 6? If so, draw a line from the basket to the number in the middle of the ride. Not only will your child be practicing important pre-algebra addition problems, but he or she will have fun with this upbeat and vividly illustrated PDF math page!

• ### Activity 3 / The Unknown Number with the Moon Phases Worksheet

Ask your kids to show you the moon in the night sky. The sometimes round shape in the night sky is the moon, and it is a source of light to the planet. Does your child know why the shape of the moon changes many times during the course of a month? Explain to them the wonders of moon phases with this simple worksheet. Then, help them solve some math. Find the equations which have ‘8’ as their missing number, and then help them trace on the dotted line to the correct answer.

Such a great app!
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.

So engaging
We love how we can focus on math with this app. It is engaging and we love how we are able to adjust and tailor the levels according to our son’s knowledge and skill levels!

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.
