The Crack the Code activity has students using a map and latitude/longitude to track down some theives.
   3. Taxicab Treasure Hunt
      A treasure is hidden in the city. Students are given a map which shows the streets of the city. After picking an intersection, the computer will state how far it is to the treasure by using the shortest distance in blocks. Students need to use this new information, along with the old information, to determine where the treasure is. Students are then asked to write an explanation of the process that they used to locate the treasure. Although this explanation cannot be submitted to the creators of the site, the teacher could informally assess students' problem-solving skills by reading their explanations. Student can also read what other students have written in the past.

   3. Grap Mole Game
   Introduction to Coordinate plane. Learn about the X and Y axis and how to plot points on the graph. Game comes in different levels of difficulty. The game is a good review, students will have fun while learning coordinate plane.
   4. Linear Inequalities
      Manipulate and visualize the solution sets of linear inequalities in slope-intercept form.
   5. Slope Intercept Form
      Interactive tool to experiment with the slope and intercept of a line. See how the slope of a line is calculated.
   6. Using Algebra and Discrete Mathematics to Investigate Population Changes in a Trout Pond
      This investigation illustrates the use of iteration, recursion and algebra to model and analyze a changing fish population. Graphs, equations, tables, and technological tools are used to investigate the effect of varying parameters on the long-term population. Students will complete a numerical analysis, a graphical analysis, and a symbolic analysis from the data.
3. A.FO.06.13 Understand that multiplying or dividing both sides of an equation by the same non-zero number creates a new equation that has the same solutions.
   1. Addition Properties
      Students play an interactive game consisting of commutative, associative, additive identity, and distributive properties. Students are given a problem with one of the properties demonstrated and the student must choose the correct property. The game immediately says if the student is correct or not and gives a running total of their score.
   2. Algebra Help
      This site gives students a step by step description of description of distributive property, order of operations solving equations, combining like terms, F.O.I.L method, simplifying exponents, and substitution method of solving equations. Students have an opportunity to work on problemns after the short lessons. This site has many different calculators available that will show all work on a problem typed in by the student just like a student would do the work.
   3. E-Lab : Two Step Equations
      Students will apply the additive inverse and multiplicative inverse properties  to solve two-step equations.
   4. Molecular Expressions, Science, Optics, and You
   This site takes you through a step by step lesson to teach powers of 10 and has an interactive applet that allows you to view several things under a micrsoscope!
   5. The Derivation of Pi
   This site contains lesson plans and resources for a student investigation of Pi. Directions are clear, directions for creating student tools for use on a computer are included as well as hyperlinks to other sites containing more information about the history of Pi. Very informativve site and useful site.
   6. The National Science Center
   This site gives a lesson plan for an activity to discover the value of pi. Students will use measuring and averaging, and hopefully discover the value of pi.
4. A.FO.06.14 Solve equations of the form ax + b = c, e.g., 3x + 8 = 15 by hand for positive
   integer coefficients less than 20, use calculators otherwise, and interpret the results.
   1. Algebra - Fun with Calendars
      A fun mathematical puzzle that shows students a use for algebra. By using a simple linear equation students can determine what four days on a calendar someone has chosen.
   2. California Here We Come!
      This site allows teams of students to choose any state capital on the east coast as their starting point. They travel west stopping at each state capital along the way and record miles traveled. Each student group will create a chart or table showing the number of miles traveled from state capital to state capital and then total numbers of miles driven. Lesson plan, evaluation, extensions, and student activity sheets are included. Skills used will involve solving linear equations and inequalities over the rational numbers, as well as solving multistep problems involving rate, average speed, distance and time, or direct variation. This includes a teacher lesson plan and is a student activity.
