Common Core and school curriculums began emphasizing non-standard algorithms over the traditional methods. The purpose of theareamodel is the mathematical development of students. The purpose of developing methods is to gain a lasting understanding of the mechanics of math rather than finding an answe...
Area Model - Multiplication and DivisionArea Model - Multiplication and Division is an app designed to develop the skills elementary students need to understand and illustrate multiplication and division problems in adherence to the common core state standards. Students benefit from a visual example of ...

A spot space orientation system by using double area CCD was introduced.The math-model was established.Using center of gravity method,the system make the precise orientation of laser spot come true.Through the measure to different rectangle,circle and triangle,the precision of center orientation can...
In the above cases, we can prove that for α > 3/2, condition (5) is satisfied (see Lemma 2 in Supplementary Note 1). For V = 0, this model is integrable and exactly solvable. For example, the Kitaev chain with long-range hopping corresponds to this class. Interestingly, ...
The first sign of change in the LIA emerged during the spring of 2018, when a large polynya formed in response to anomalous northward winds which drove sea ice away from the coast9,10. These winds were so strong that model simulations indicated that the polynya would have developed even with...
In order to make a scientific and objective evaluation for urban residential area environmental quality,the article proposed an improved fuzzy comprehensive evaluation model,used fuzzy math theory in the evaluation of environmental quality,made a multi-target index structure according to the features of ...
Early Childhood Teachers' Professional Learning in Early Algebraic Thinking: A Model that Supports New Knowledge and Pedagogy. The implementation of a new mathematics syllabus in the elementary context is problematic, especially if it contains a new content area. A professional dev... E Warren - ...
We used a multiple regression quadratic assignment procedure (MRQAP) to assess how social associations (using the simple ratio index, or SRI49) affect similarity in female PA-use (Pearson’s pairwise correlation in BSI; see “Methods”). This model showed a significant relationship (p < ...
