The Internet Archive discovers and captures web pages through many different web crawls.
At any given time several distinct crawls are running, some for months, and some every day or longer.
View the web archive through the Wayback Machine.
Content crawled via the Wayback Machine Live Proxy mostly by the Save Page Now feature on web.archive.org.
Liveweb proxy is a component of Internet Archive?s wayback machine project. The liveweb proxy captures the content of a web page in real time, archives it into a ARC or WARC file and returns the ARC/WARC record back to the wayback machine to process. The recorded ARC/WARC file becomes part of the wayback machine in due course of time.
Elementary Math is a skill that allows children in grades 1 through 4 to practice basic math questions. The skill will ask what kind of math should be practiced in a session. The choices are addition, subtraction, multiplication, or division. Once a choice is made, the skill generates 5 questions on that type of problem. Each response is marked correct or incorrect and instant feedback is given. The results of a session are stored so that the user is reminded what he or she worked on last time. To start the skill, or a new session, say "Open Elementary Math". After that, the skill will guide the user on what kind of math questions to practice. You can set the difficulty level to easy (default), medium, or hard.
