Whys….. US students perform near the bottom by the end of high school. Singapore Math NCTM highlights the need for a well defined curriculum Movement toward Conceptual Math Catawba County is training every teacher in Math Foundations

Why? Number & Operations Geometry Algebra Data Analysis and Probability Measurement

Try for 100 Two players Take turns rolling a die Each must decide if the number will go in the ones or tens place The winner is the one that is closest to 100 without going over.

Try for 100 TensOnes 1. 2. 3. 4. 5. 6.
