Pick's Theorem simply has us count up the number of points on the boundary of the polygon (where the rubber band touches a nail head) and divide this number in half. Then add the number of points in the interior of the polygon (inside and not touching the rubber band) and subtract 1. Area = Boundary points/2 + interior points -1

3. Introduction to Pick's Theorem
OBJECTIVE: 1.2.1 Understand how a change in one linear dimension affects surface area and volume of rectangular prisms and cylinders and how changes in two linear dimensions affect perimeter and area of rectangles. 1.2.5 Use formulas to determine measurements related to circles, triangles, and rectangular prisms.4.1.2 Extract numerical, measurement, geometric, probability, statistical, and/or algebraic information from multiple sources. ACTIVITIES/ASSESSMENT: Page 26 Prob 3.3 a - only fold paper into triangle, rectangle, pentagon and hexagon. on cm grid paper, determine area of the base.. NOTES: Pick's Theorem Area = (boundary points)/2+ interior points -1; HOMEWORK: Handout-Place it Right E

2. Warm-Ups: Circuference from radius and diameter
3. Model rectangular prism volumes to/from cylinders
OBJECTIVE: 1.2.1 Understand how a change in one linear dimension affects surface area and volume of rectangular prisms and cylinders and how changes in two linear dimensions affect perimeter and area of rectangles. 1.2.5 Use formulas to determine measurements related to circles, triangles, and rectangular prisms.4.1.2 Extract numerical, measurement, geometric, probability, statistical, and/or algebraic information from multiple sources. ACTIVITIES/ASSESSMENT: Warm-Ups: Circuference from radius and diameter. Model rectangular prism volumes to/from cylinders - this is a lead in to problem 4.3 - the juice boxes. NOTES: HOMEWORK: Find a l, w, and h for a volume of 200 cm³
