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 :-)
