Number magnitude estimation has been investigated over the last decades using different tasks including non-symbolic numerosity but also number line estimation tasks. Recently, a bi-directional mapping process was suggested for numerosity estimation accounting for underestimation in a perception version of the task i. In the present study, we evaluated the generalizability of these estimation biases in perception and production tasks to bounded and unbounded number line estimation.
One of my favorite quotes about mathematics is from John von Neumann:. You just get used to them. On one level, this runs against everything I believe as a teacher.

The NumberLine tool is a palette for students to input solutions to exercises that require the use of a number line. There are two modes: one is used to locate points, graph intervals, and graph inequalities on a number line; the other to indicate point positions on a number line graph. The key icon is displayed at the bottom of the question next to the numerical portion of the answer key.
Pandoc is a Haskell library for converting from one markup format to another, and a command-line tool that uses this library. For the full lists of input and output formats, see the --from and --to options below. Pandoc has a modular design: it consists of a set of readers, which parse text in a given format and produce a native representation of the document an abstract syntax tree or ASTand a set of writers, which convert this native representation into a target format.
These new elements are not real numbers. It is useful in describing various limiting behaviors in calculus and mathematical analysisespecially in the theory of measure and integration. For example, consider the function.
There is a really nice package, linenowhich provides line-numbering and various options for customization, some of which I will discuss further below. The most common use is continuous line numbering throughout the document. The following two lines in the preamble will do the trick:. If you do not leave an empty line between the previous and the actual paragraph, the previous may also get numbered.
