Introduction Word length and phrase length influence the ease of reading and understanding of a given text. Short words are usually more common (Zipf's law). Short sentences require less abstraction ability to understand. The readability analysis could be useful to make a text better, augmenting its accessibility. Why have we developed this? The readability index tells us how easy a given text is to understand. A well-written text is effective, easy to understand and quick to read. This index helps us understand the text's complexity in order to better schedule the activities of translators and revisers. More than ever, written information, especially in the Internet, must be direct and well structured. This analysis can help achieve both goals.

Need a pentagonal pyramid that's six inches tall? Or a number line that goes from ‑18 to 32 by 5's? Or a set of pattern blocks where all shapes have one-inch sides? You can create all those things and more with the Dynamic Paper tool. Place the images you want, then export it as a PDF activity sheet for your students or as a JPEG image for use in other applications or on the web. Instructions   This applet allows you to create the following: Nets – two-dimensional outlines of three-dimensional shapes, including regular polyhedra, prisms, pyramids, cylinders and cones Graph Paper – coordinate graphs, polar coordinates, logarithmic graph paper Number Lines – including positive and negative coordinates Number Grids – hundreds boards and the like Tessellations – tiling patterns involving triangles, quadrilaterals, and hexagons Shapes – pattern blocks, attribute blocks, and color tiles Spinners – up to 16 sectors, with adjustable sizes

This could have happened at some point early in human evolution, when in order to survive, people were forced to cooperate in hunting game or gathering fruit. The path to obligatory cooperation — one that other primates did not take — led to social rules and their enforcement, to human altruism and to language. “Humans putting their heads together in shared cooperative activities are thus the originators of human culture,” Dr. Tomasello writes.
