ACE 1.4 In the Chips

LARGE GROUP
Today we worked on problem 1.4, In the Chips, and used a chip model for integers, in which red chips represent negative numbers and black chips represent positive numbers. Students also finished their conference preparations, reflecting on one strength and one challenge work. Sima met with a few students to go over their reflections. Class notes may be downloaded here.

SMALL GROUPS
Cory was out but MaryBeth taught today. We did more work visualizing number lines, and practiced positive and negative moves on the visualized number line. Students made cards for: Integers and Change - + change (to the right), - change (to the left). We learned that changes have both a quantity and a direction (positive or negative). We went over problem 1.2, #F and the ACE 1.2 homework yesterday, and started Problem 1.3, What's the Change?
