Patterns, Functions, and Algebra
Assignment for Friday June 26, 2009
LAB WARM-UP: Use the Library of Virtual Manipulatives
(http://nlvm.usu.edu/en/nav/vlibrary.html then click the Algebra 6-8 cell and
the manipulative called Balance Scales Negative to solve 10-12 equations.
For a balance beam that is more developmentally appropriate for elementary
students go to
http://www.mste.uiuc.edu/users/pavel/java/balance/index.html#sim (Be
patient for the different beams to load after clicking the links for 2 weights, 3
weights, etc.)
HOMEWORK:
1. Use the Library of Virtual Manipulatives
(http://nlvm.usu.edu/en/nav/vlibrary.html Click the Algebra 6-8 cell and
the virtual manipulative Grapher (or a graphing calculator if you do not
have internet at home) to graph a variety of functions.
2. McGlean!
Here are some basic guidelines to get you started, but venture out from these
to enhance your learning.
1. Graph function families such as x+7, 2x+7, 3x+7 … 10x+7
2. Graph several related families such as those generated by x-7
3. Look at families of functions with x2 and x3 (Standard form for
families of quadratic equations is ax2+bx+c) and similarly for cubic
equations ax3+bx2+cx+d; the brave can look at other exponential
functions.
When you have finished your exploration. Write a summary of what
you have learned. (If you did not learn anything or if the learning has
no application to your classroom, continue exploring and
investigating!) A format for your writing is given on the following
page.
