Abacus Deluxe vs Simplifying Complex Fractions

Abacus Deluxe is a simulation of a real Chinese abacus with many special additional features. The abacus is one of the first machines used for calculating. With this abacus students can learn to count and do basic arithmetic in a fun interactive way. Abacus Deluxe is a great tool for teaching place value concepts to elementary students. A typical abacus is made from a wooden frame, with either bamboo or metal rods, and wooden or ceramic beads. People who master the abacus spend a great deal of time practicing the use of the device. With Abacus Deluxe students can practice math in a fun and interactive way and just like an abacus master become faster with mental math than a person using an electronic calculator. In China and other parts of Asia the abacus is still used widely to count and calculate. We designed our abacus to be a fun way to learn counting, place value and calculating both small and large numbers.

The DOST Courseware is a locally-produced, all-original Filipino highly interactive multimedia educational application packages that are conceptualized, digitized and produced as spearheaded by the Science Education Institute (SEI-DOST) in partnership with the Advanced Science and Technology Institute (ASTI-DOST) and in cooperation with the Department of Education (DepEd), Philippine Normal University (PNU) and University of the Philippines-National Institute for Science and Mathematics Education (UP-NISMED), which aims to develop information and communication technology learning innovation to support the upgrading and improvement of science and mathematics education in the country. The DOST Courseware are provided for free to schools and are also made available online as supplemental resources for teachers and student as a fun and interactive approach to e-learning and blended learning. The Grade 7 DOST Courseware is composed of 120 lessons overall, 73 lessons in Science where it covered the domains on: Matter; Force, Motion and Energy, Living Things and Their Environment and Earth and Space while the 60 lessons in Mathematic covered the domains on: Numbers and Number Sense, Patterns and Algebra, and Geometry. The Grade 8 DOST Courseware is composed of 118 lessons overall, 61 lessons in Science where it covered the domains on: Parts and Functions, Ecosystems, Heredity: Inheritance and Variation of Traits, Structures and Functions, Biodiversity, and Evolution, while the 57 lessons in Mathematics covered the domains on: Linear Equations, Quadratic Equations, Rational Algebraic Equations, Integral Exponents, Radicals, Arithmetic Sequence and Geometric Sequence. The themes of the courseware for Grades 7 and 8, Magicademy, Freddy’s Lab and D’nayao will surely amuse the users as they explore these distinct worlds while learning at the same time.
