Finger Numbers vs Hands

Finger Numbers is a motivating learning app that builds rapid quantity recognition (quasi‑simultaneous subitizing) and a robust sense of number and operations for early math. This release is a complete technical rebuild with expanded content—designed for children, parents, and teachers. What children practice: - Recognizing quantities at a glance and matching them with finger touches - Automating number decompositions, complements to 10, and strategies like the “Power of 5” - Moving fluently between representations (fingers, dots, mixed) Game and practice modes: - Basics: Fingers, Dots, Mixed - Pattern Recognition: structured arrangements - Calculation Strategies: Power of 5, complements to 10, How many are missing?, decompositions - Two Hands: cooperative/competitive split‑screen number decomposition - Jump and Run: an action mini‑game controlled by finger numbers Adapt to each learner: - Flexible number range from 3 to 10 fingers (start with 3-5 Fingers for learning the input) - Time pressure can be enabled/disabled as needed - Visual aids and flash‑view controls - Multi‑user profiles with individual progress; Guest mode without recording For teachers - Diagnostic reports with solution times, success rates, and strategy insights - Protected area to review learning progress - AI‑powered summaries with didactic guidance Note: On iPad, system gestures (e.g., 4–5‑finger gestures) may interfere with multi‑finger input. Consider disabling multitasking gestures in system settings if needed. Languages: German, English, Spanish, French, Japanese, Chinese (Simplified)

Hands-On Math: Pentominoes creates a virtual math playground where students explore, investigate and discover mathematical concepts. Students use the classic 7-piece set of tangram pieces on an interactive playground to discover and explore, visual problem solving, geometry, fractions, angles, shapes, and much more. Using Hands-On Math: Pentominoes students can develop the following important mathematical concepts: • Shapes and Properties • Logical Patterns and Sequences • Meaning of Fractions • Classifying Figures and Measurement • Creativity and Design Features: • Open-ended Pentominoes Playground. • Supports Discovery and Directed Teaching Strategies. • Problem Solving Activities which Can Be Solved Using Virtual Manipulatives. • Helps to Build an Intuitive Understanding of Geometry. • On/Off Options and Controls for Various Features. Pentominoes Playground There are 12 permutations for geometric figures made up of 5 squares. The pieces collectively are known as pentominoes. In this app the pieces are provided for use on the Hands-On Math Playground. The Playground offers a snap-to grid function and pieces can be placed, moved, arranged, rotated and grouped in order to represent mathematical ideas. Topics: • The Properties of Geometric Shapes • Visual Problem Solving • Fractions (Shading Parts of a Whole) • Congruence and Similarity • Symmetry • Rotations and Translation Activities Students use a slider or buttons to select an activity. Here is a sample activity where the object is to move the correct pentomino pieces into the space in order to completely cover the congruent shapes.
