Research shows fluency in the foundation skills is critical to reading comprehension. Our apps are designed for and tested by typical and special needs children.

We collect NO private information in our app, and our apps do not allow unrestricted web access. Inferencing is a key component of reading comprehension. If you can't infer fluently, you can't understand the story. Help your child now by getting started with our Inference Ace app. While you're at it, check out our other apps that target WH questions, identifying inference clues and identifying the main idea of a sentence or paragraph. We take customer service very seriously! If you ever have a problem or find that we've missed something, contact us at our website and we will do our best to fix the problem. ** Note: Inference Ace and Inference Clues intentionally use similar data sets. However, different skills are targeted. Also, when working through this app, you will encounter different variants of the same examples many times as we teach our players to derive multiple inferences from a single sentence -- just like expert readers do. This is an intentional feature, not a bug :-)

This game is bursting with learning! Your little ones will pop their way into a whimsical world to learn letter sounds, phonics, and new words! Compatible with the Square Panda Playset, children love playtime as they use Square Panda smart letters to hear letter sounds and spell out new words. The more letters the child puts in the Playset, the more bubbles they get to pop! As your child pops bubbles they hear phonemic sounds and discover what real words are hiding behind the world of bubbles! Perfect for children learning: Concepts about print, the Alphabet, letter sounds, word construction, vocabulary comprehension, spelling and reading fluency Phonics Benefits: Children learn that symbols correspond with specific phonemic sounds and when placed individually or together, create brand new sounds. These sounds tied-together have meaning and this meaning is the construct for the entire English language. Features: Pictures of children’s first words Hundreds of phonemic sound reinforcements Surprises behind every bubble pop! The National Reading Panel recommends that children are taught phonemic awareness of individual sounds in words in this order: first, middle and last. When you find letters in Square Panda Bubbles, children learn the order letters are placed in words and important concepts about print language. For ages 2-5. Square Panda Playset required to play.
