Apportionment Info and Calculators

An Introduction to Apportionment
 
Calculate apportionment using Hamilton's Method
The apportionment method suggested by Alexander Hamilton was approved by Congress in 1791, but was subsequently vetoed by president Washington - in the very first exercise of the veto power by President of the United States. Hamilton's method was adopted by the US Congress in 1852 and was in use through 1911 when it was replaced by Webster's method.
Video

Calculate apportionment using Jefferson's Method
The apportionment method suggested by future president Thomas Jefferson as a competitor to Hamilton's method. Jefferson's method was the first apportionment method used by the US Congress starting at 1791 through 1842 when it was replaced by Webster's method.   
Video

Calculate apportionment using Adam's Method
The apportionment method suggested in 1822 by former president John Quincy Adams as a remedy for the ills of Hamilton's method was never used by the US Congress.
Video

Calculate apportionment using Webster's Method 
Daniel Webster proposed his apportionment method in 1832.It was adopted by the Congress in 1842, and then replaced by Hamilton's in 1852. It was again adopted in 1911. Finally, it was replaced by Huntington-Hill's method in 1941.

Calculate apportionment using the Huntington-Hill Method
Huntington-Hill's method is the current method of seat apportionment used by the US Congress. It has been signed in law by President Roosevelt on November 15, 1941.

New this Spring

In an attempt to increase communication, I will be implementing a new texting system - Remind101 - that will allow me to send HW assignments and other announcements directly to your cellphone.

Remind101 provides a safe way for teachers to text students and stay in touch with parents.  All phone numbers are kept private, so no personal information or phone numbers will be shared with anyone else.

To sign up for this totally free option ...
- go to www.remind101.com
- click the "Sign up as student or parent" button
- use class code "mrsondg"
- follow the onscreen directions

On the initial sign in page, you will also see two buttons that will provide you (and your parents) with more detailed information on the development and safety of Remind101.  Please contact me via e-mail (masondg@ilstu.edu) if you or your parents have any additional questions or concerns.

Welcome Back!

It looks like we will finally get back to the classroom tomorrow, Jan.8.  Please bring your fully charged laptop to class with you, as we will continue our discussion of congruent triangles and begin to explore methods for proving triangles congruent.
