1. Harvey Plotter
2. Discuss 3.1

OBJECTIVE: 1.3.1 Understand the concept of similarity. 1.2.1 Analyze how a change in a linear dimension affects other linear measurements (perimeter, circumference) and area measurements. 1.2.3 Understand how the unit of measure affects the precision of measurement 1.1.4 Understand the concept of direct proportion. ACTIVITIES/ASSESSMENT: Start a discussion of 3.1 - Nail down the requirements of similarity and scale factor. NOTES: Start on scale factors which are not whole numbers or simple fractions. HOMEWORK: P33 2-4

1. HOMEWORK Due today: P33 2-4
2. P29 Problem 3.2 Building with Rep-Tiles

OBJECTIVE: 1.3.1 Understand the concept of similarity. 1.2.1 Analyze how a change in a linear dimension affects other linear measurements (perimeter, circumference) and area measurements. 1.2.3 Understand how the unit of measure affects the precision of measurement 1.1.4 Understand the concept of direct proportion. ACTIVITIES/ASSESSMENT: Evaluate the shapes form the shape set (Labsheet 3.2) and determine which ones are rep-tiles - sketch the solutions for the ones so noted. NOTES: Draw and sketch are 2 different words. HOMEWORK: Labsheet 3.2 Draw lines of symmetry
