|Multi-‐ grade (3–6)||Halves, Thirds & Sixths (from illustrativemath.org)
Task (3-5): What fraction of the area of the rectangle is shaded blue. Name the fraction in as many ways as you can. Explain your answers.
Task (modified for 6): Find a fraction equivalent to 3/8. Use diagram, equations, and mathematical principles to prove the fractions are equivalent.
|Depending on grade Definitions of fractions. Equivalency of fractions: Explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using visual fraction models. Explaining equivalence … by reasoning about their size.||Packet Overview
|HSAlg I||DJ for the Prom
Task: In preparation for the Prom, students are researching the costs of two local DJ companies. Music Makers charges a fee of $200 and an additional $175 per hour. Dance Partners does not charge an initial fee, but charges $225 per hour. Which company would be more cost effective for the prom committee? Write a mathematical argument to support your decision.
|Depending on student approach: Understand the connection between proportional relationships and lines. Solve pairs of simultaneous linear equations.||Packet Overview|

Commentary on Student Work
Protocols to guide work sample sorting activity
Protocol designed for ARPs (33-40 mins)
Protocol shortened (23-28 mins)
Protocol followed by full group discussion (40-55 mins). This is useful for larger group PD.
