Build stronger vocabulary, comprehension, and critical thinking through interactive categorization practice. Developed by certified Speech-Language Pathologists, Categories Learning Center is a multi-level, multi-player app designed to strengthen language comprehension and organization skills for learners of all ages. Categorization is a foundational cognitive and linguistic skill that supports word retrieval, memory, and reading comprehension. Rooted in research on language development and processing, Categories Learning Center provides fun, structured practice in identifying, grouping, and labeling objects based on shared features. These skills are essential for forming semantic networks that aid expressive language, reading, and writing. Children and adults alike can benefit—whether developing new vocabulary or improving word-finding and comprehension skills. Why Categorization Matters Being able to identify how words and objects relate helps learners store and retrieve information more effectively. Research shows that poor categorization skills can impact comprehension, vocabulary, and communication (Partyka & Kresheck, 1983; Semel, Wiig, & Secord, 2003; Richard & Hanner, 2005). Categories Learning Center helps strengthen these essential connections through engaging, evidence-based activities. Use Categories Learning Center to: • Teach how to sort objects that belong to the same category • Expand receptive and expressive vocabulary through visual learning • Improve word-finding and semantic organization • Reinforce reading comprehension through category-based learning • Track and measure progress with session-by-session performance reports Activities Include: • Receptive (Non-Verbal) Activities • Level 1: Sorting dissimilar objects • Level 2: Sorting similar objects • Where Does It Go?: Placing an object into one of three category options • Expressive Activities • Category Naming: Provide the correct category name for a group of objects • Category Selection: Identify which of four category names fits a group of objects • Extended Practice: Name additional items within each category to strengthen recall App Features: • Multi-player mode – up to 4 users at once • Multiple levels of difficulty to support skill progression • Customizable receptive activities with 2 or 3 category choices • Automatic progress tracking and data reporting • Reports that can be emailed, printed, or stored for future reference Categories Learning Center combines clinical expertise with engaging technology to make therapy and learning both effective and enjoyable. Whether used in schools, therapy sessions, or at home, this app provides a powerful tool for improving comprehension, organization, and expressive language skills.

Feature Function Class is a powerful visual teaching tool designed for educators, therapists, and parents working on receptive language and categorization skills. Built specifically for Feature-Function-Class (FFC) training, this app streamlines the process of presenting images and testing identification skills. WHAT IS FEATURE-FUNCTION-CLASS? Feature-Function-Class is a proven teaching methodology used in Applied Behavior Analysis (ABA) therapy and early childhood education. It helps learners identify and categorize objects by: - Features — What you SEE (color, shape, parts) - Functions — What it DOES or how you USE it - Classes — What CATEGORY it belongs to HOW IT WORKS Select any Feature, Function, or Class filter and the app instantly displays a set of images — with one image always matching your selected criteria. This creates natural teaching opportunities and quick identification trials. KEY FEATURES ◆ 300+ Pre-Tagged Images Start immediately with a library of high-quality, royalty-free images professionally tagged with features, functions, and classes. ◆ Smart Filtering Filter by Feature (spots, red, round), Function (cuts, you sit on it), or Class (animals, furniture, food). Combine filters to narrow results. ◆ Shuffle Mode Keep training fresh — Shuffle loads new images while always maintaining one that matches your filter. Cycle through your entire library without losing focus on the training target. ◆ Reorder Mode Test true recognition — Reorder keeps the same images but shuffles their positions. Perfect for confirming the learner recognizes the target, not just its location on screen. ◆ Adjustable Grid Size Scale difficulty from 2 to 8 images. Start simple and increase complexity as skills improve. ◆ Save & Load Sets Working with a client over multiple sessions? Save your image set once and reload it instantly. Maintain consistency across training sessions. ◆ Import Your Own Photos Add personal photos and tag them with custom features, functions, and classes. Include familiar objects, family members, or items specific to your learner's environment. ◆ Custom Tags Create your own feature, function, and class tags to extend the built-in library and personalize training. DESIGNED FOR - ABA Therapists & BCBAs - Speech-Language Pathologists - Special Education Teachers - Early Intervention Specialists - Parents supporting skill development at home Whether you're running discrete trials, building receptive vocabulary, or working on categorization skills, Feature Function Class gives you the tools to create effective, engaging training sessions.
