## What is Number Monster?

*“Amazing app that keeps my son practicing mental math for hours! ”
*“I initially downloaded this app for my 4-year-old to kill time, and I never would've thought it'd improve his math grades. Thank you.”
* “Thumbs up for understanding every kid is different! I downloaded Number Monster for my preschooler, and I love how it lets me adjust difficulty level for my child so that he could learn at his own pace.”

Looking for an engaging math game for your child? Number Monster will keep your kid playing for hours. It's great for kids aged 3-10. Play it once & they'll get the hang of it. Play it again & they'll grasp addition & subtraction within 20. Next thing you know, they've spent hours playing and they're killing it in math classes. 

Number Monster takes place on a board, filled with "monsters" valued 1 through 5. Move these monsters around the board to merge them. When kids make a ten with 2 monsters, the monsters will cancel each other. In the advanced difficulty level, kids will have to make a twenty or other targeted number to cancel the monsters. 

【What Number Monster Covers】
- 10-frame addition
- 20-frame addition
- 10-frame subtraction
- 20-frame subtraction

【Features】

- Custom mode available for you to set any target number according to your kid's math skills.

【How to Play】
The goal of the game is to swipe 2 monsters into a position to get a 10 (or other target numbers). This will result in the merger of the monsters. After the merger, the monsters will disappear and new monsters will fall onto the board. Keep repeating this until the board is filled and there is no more space for additional monsters.

My mom is always telling me to practice math.I thought it was boring until I got this app.I’m on the medium level of adding.I play math everyday all thanks to this particular game.

### 5/5 — Awesome

*2019-12-10*

My 6 year old loves it and learns a lot while doing so!

### 5/5 — Diverse presentation of concepts & no ads!

*2019-12-10, version 1.1.2*

We love this app. We use it in conjunction with homeschooling. It presents math concepts in various ways to ensure a child truly understands it. Wording, visuals, and approach are rotated through. I also love the weekly email report on the progress. You can always go back to practice something again. My daughter loves it. It isn't so \fun focused\ that learning time is wasted, but isn't so learning heavy that it loses her. She is rather advanced in math for her age so it was helpful that the program reads the questions and doesn't require writing to complete them.

### 5/5 — A good supplement

*2019-12-10, version 1.1.2*

My five years old daughter likes number monster very much. She answers thirty questions a day. She already finished kindergarten and first grade levels in three months. She is doing the 2nd grade level now. She also reviews the 1st grade questions everyday. This program is very organized. My daughter has great fun.
