Math amplify fractions
This book provides international perspectives on the use of digital technologies in primary, lower secondary and upper secondary school mathematics. It gathers contributions by the members of three topic study groups from the 13th International Congress on Mathematical Education and covers a range of themes that will appeal to researchers and practitioners alike. The chapters include studies on technologies such as virtual manipulatives, apps, custom-built assessment tools, dynamic geometry, computer algebra systems and communication tools. The diverse technologies considered provide a broad overview of the potential that digital solutions hold in connection with teaching and learning. The chapters provide both a snapshot of the status quo of technologies in school mathematics, and outline how they might impact school mathematics ten to twenty years from now.

This paper discusses Freudenthal's didactical phenomenology for the mathematical structures related to measurement. Freudenthal starts with the set G of all objects having the attribute of weight, an attribute that is to be measured. Addition is interpreted in terms of the mental actions associated with measurement and, in the case of weights, it consists on the process of placing weights on one of the two dishes of a balance in order to balance them with a predetermined gauge, its fractions or multiples thereof, which are placed on the other.
Their total weight is obtained by comparison with a predetermined gauge. The second operation, between weights and positive integers, allow weights to be amplified by adding as many times as desired their weight measure.
A related operation to amplification is that of contraction by dividing the weight into as many equal parts as desired. Freudenthal then extends his definitions in order to assign a meaning to the multiplication of a measure by, first, any positive rational number, and, second, by completeness, to any real number.
Freudenthal's didactical phenomenology is based on the historical phenomenology of measurement, fractions, decimals and percentages. It is a central tenet of Realistic Mathematics Education RME that didactical phenomenologies of mathematical structures constitute proposals from which to make cognitively advantageous teaching sequences for the relevant mathematical structures. We discuss how Freudenthal's phenomenology of the mathematical structures for measurement gets translated into the mathematical models associated with the rational numbers.
Finally, we make reference to a paradigmatic teaching unit which incorporates coherently Freudenthal's didactical phenomenology. Mathematics Commons. Advanced Search. Privacy Copyright.

The purpose of this number talk is to elicit strategies and understandings students have for dividing a fraction by a fraction. Later in this lesson, students will need to be able to divide a fraction by a fraction to solve problems in contexts. Four problems are given. It may not be possible to share every strategy. Consider gathering only two or three different strategies per problem, saving most of the time for the final question.

The decimal module provides support for fast correctly-rounded decimal floating point arithmetic. It offers several advantages over the float datatype:. Decimal numbers can be represented exactly. In contrast, numbers like 1. End users typically would not expect 1. The exactness carries over into arithmetic.

Amplify is a US-focused educational publisher reimagining the way teachers teach and students learn. As part of our focus on Maths, we developed Mlob Rule, a game which sets out to make fractions less intimidating and easier to understand. Mlob Rule is a tactile, turn-based puzzle game set in the mythical world of Fractopia. Play takes place in a grid-based world in which the competing Mlob tribes face off in battle. As the player creates whole numbers from their Mlob fractions, they become charged attacking formations or defensive walls. The campaign modes takes the player on a journey across Fractopia, fighting one Mlob tribe after another. Battles begin simply, featuring fractions that share a common denominator on small battle grids.

Congratulations to the finalists and winners of The EdTech Awards and may their resolve inspire others! The innovators, leaders, and trendsetters represented here are dauntless, dedicated, and determined in their work. In this age of rapidly accelerating technological growth, it might be easy to lose sight of what moves everything forward: the indomitable power of the human spirit. But in no other field is the human spirit more alive than education, where educators and supporting technologists are literally shaping our future.

Children learn and use various strategies to solve math problems. One way children's math learning can be supported is through their use of and exposure to hand gestures. Children's self-produced gestures can reveal unique, math-relevant knowledge that is not contained in their speech. Additionally, these gestures can assist with their math learning and problem solving by supporting their cognitive processes, such as executive function.
