Algebra Part 2

Students spent this week in math using what they learned about equations to make input/output tables and graph their data on coordinate grids!

Toothpick Challenge!
What's the pattern?  Students made tables showing how many toothpicks it takes to make 1 triangle..2,3,4...
They discovered the pattern could be described as 2x+1=y.
So how many toothpicks does it take to make 125 triangles?

Real World Algebra!
Students created real world situation problems, tables showing possible outcomes, and graphed their data.  What do you get when you graph any function table?
A straight line!

 Here are the winners of our 100s Chart Game where students made up equivalent equations for a number 1-100 that they selected.
