Hands vs Environmental Engineering PRO

Hands-On Math: Tangrams creates a virtual math playground where students explore, investigate and discover mathematical concepts. Students use the classic 7-piece tangram on an interactive playground to discover and explore, puzzles, designs, geometry, fractions, angles, shapes, and much more. Using Hands-On Math: Tangrams students can develop the following important mathematical concepts: Shapes and Properties Logical Patterns and Sequences Meaning of Fractions Classifying Angles and Measurement Creativity and Design Key Features: Open-ended Tangram 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. Tangrams Playground The classic 7 tangram pieces are provided for use on the Hands-On Math Playground. Pieces can be placed, moved, arranged, rotated and grouped in order to represent mathematical ideas. Topics: The Properties of Geometric Shapes Visual Puzzle Problem Solving Fractions (Shading Parts of a Whole) Acute, Right and Obtuse Angles Symmetry Rotations and Translation

Environmental Engineering Practice is an educational application designed to help students understand and practice key concepts related to environmental protection, water and wastewater treatment, pollution control, and sustainable development. The app focuses on structured learning through chapter-wise quizzes, mock tests, and daily quizzes aligned with standard environmental engineering curricula. Users can practice questions from individual topics, attempt mock tests for overall assessment, and monitor their performance using statistics. The app supports self-study, classroom learning, and examination preparation for engineering students. Topics Included 1. Introduction to Environmental Engineering Scope of environmental engineering, environmental pollution, sustainable development, environmental laws, and environmental impact assessment. 2. Water Supply Engineering Water demand, sources of water, intake structures, treatment processes, distribution systems, and water quality standards. 3. Water Treatment Methods Screening, sedimentation, coagulation and flocculation, filtration, disinfection, and softening. 4. Wastewater Engineering Sewerage systems, wastewater characteristics, treatment processes, and effluent disposal. 5.
