Scientific+Notation

=Scientific Notation=

Powers of Ten-website that shows sizes of different objects that are the different powers of ten.

Borrowed from an Algebra One textbook- can't remember which one. I used to just print this out and have students examine the list. The past few years I have the "is" and "is not" examples written on sentence strips. I put them up one by one, and have additional examples for students to bring up and place when they think they have the idea. Then I ask students to write a definition for what it means for a number to be in scientific notation and we come up with a class consensus.

- I use this activity to have students explore what it means to multiply numbers by powers of 10 so that they can understand how to convert from scientific notation to standard.

- Includes converting to and from scientific notation. Goes beyond 7th grade assessment limits to include negative powers of ten, but can easily be modified.
 * [[file:Around the World Scientific Notation Questions only positive exponents.doc]]- This version has only positive exponents and numbers greater than one whole to match the assessment limits of 7th grade.

- Recording sheet for the activity described above.

- A Discovery/Notes sheet...First has students look at examples/non examples of scientific notation in order to develop a definition. Next, place for notes for converting between scientific notation and standard form. Extends to see how to take a number like 1400 x 10 to the fifth power could be written in scientific notation.

- basic list of "is" and "isn't" in scientific notation, followed by practice and a few real life examples.

- Connects operations with scientific notation to multiplying and dividing monomials...second page has practice problems just retyped from a practice Glencoe algebra book worksheet.

- Just some practice problems to be used in any number of activities.
