## What is Letter Recognition?

Recognising and remembering the different forms that a letter can take increases children’s awareness as they see them in other contexts and begin to use them in their early writing. The simple game play of this visually-engaging app follows the rules of pelmanism. Select a pair of letter pebbles, hear their name and sound and watch to see if they match. If a pair is found, they remain face up. If not, they turn over. Try to remember what you saw though as you might need some of those pebbles later! When a game is over, a new set of pebbles appears with letters selected randomly.

Teacher options allow you to choose what matching takes place: lowercase to lowercase, uppercase to uppercase or uppercase to lowercase.

FEATURES

- Learn the name and sound of each letter and its lowercase/uppercase shape
- Turn a pair of pebbles to find matching letters
- Use settings to choose matching options: UC-UC, lc-lc or lc-UC
- Use settings to reduce/increase the number of pebbles used in a game
- A Read Me file with guidance on other ways to support letter recognition in children
- No third-party advertising
- No in-app purchases.

### 1/5 — Super Glitchy  - would not recommend

*2024-02-01*

Volume cuts out regularly and for long periods of time.

You can select certain settings, but they change on their own to different settings.

It’s not possible to adjust the difficulty level (number of tiles in game)

### 1/5 — Activate?

*2019-01-21*

Absolutely no instructions on what to do, just a blank screen that says activate and no way to do so.

### 1/5 — Looks three but it's not

*2017-08-22*

I had to go online and sign up. Then I try to get the app and realize that I had to pay over $10 for the cheaper apps and most of them were over $20. I'm just trying to find an app that I can use for student in my class that is having difficulty with letter sound. It is misleading because it doesn't tell you that you have to purchase this up it just says get. It also doesn't tell you that you have to go to the website to purchase it.
