1st Calc vs Hands

„1st Calc“ is an Abacus-style bead frame, that helps primary school children to discover numbers up to 100. It provides them with a visual tool to play with numbers and lets them solve addition and subtraction problems. It is based on the latest math-teaching knowledge and its use contributes significantly to avoid any mathematical disabilities at an early stage and counteract this. „1st Calc“ is an invaluable tool harvesting the children's motivation to use the iPad or iPhone and makes up with a more fun learning experience. FEATURES · Selectable range of numbers: 0 - 20 or 0 - 100 · Bead frame for children · Choose between 4 different colors · Optional live cam view as background We will provide you with further updates. "1st Calc" will then be able to generate addition and subtraction problems, to guide the child through the solution process and to control and diagnose the child's input.

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.
