                     SAME BUT DIFFERENT MATH


 6 - 2 and 6 - 1 - 1.

 A square and a diamond.

 The times of 6:46 and 12:46 on an analog clockface.

 Within each pair, what's different? What's the same?

 A website that juxtaposes such pairs launched Tuesday. With
 "Same But Different," creator Sue Looney aims to call attention
 to how two things can share commonalities and how they
 can differ.

 Categories include--

    - early numeracy;
    - addition/subtraction;
    - multiplication/division;
    - measurement;
    - place value;
    - fractions, ratios; 
    - geometry; and
    - algebra.

 Looney provides a six-step instructional routine for "Same But
 Different." Click her new site's "About" tab and then "How to
 Use" for more on the number talk that she recommends, along
 with talk moves by teachers to keep the dialogue going among
 and between students.

 different demographic groups' population sizes, median
 household incomes, and levels of education:
