    Study Notes

    Unit 1: Describing Objects and Math Basics

    • Objectives:
      • Identify types of geometric objects.
      • Describe geometric objects in English, focusing on physical features, shapes, properties, and locations.
      • Use descriptive phrases, sentence structures, and verb phrases for descriptions.
      • Describe numbers and equations in English.

    1.2 Introduction

    • Students need English skills for various fields, including describing people, places, and objects.
    • This unit covers types of geometric objects, their properties, locations, and basic math.

    1.3 Vocabulary

    • Shapes (2D):
      • shape
      • rectangle
      • triangle
      • ellipse
      • circle
      • vertex
      • circumference
      • angle
      • locate
      • division
      • addition
    • Shapes (3D):
      • square
      • pyramid
      • sphere
      • edge
      • radius
      • diameter
      • situate
      • subtraction
      • multiplication
      • power

    1.4 Geometric Objects and Types

    • Geometric objects/shapes remain consistent even if moved, resized, rotated, or reflected.
    • 2D shapes: Defined by points (vertices) and lines (forming closed chains) which create polygons (e.g., triangles, squares, pentagons) or curves (e.g., circles, ellipses).
    • 3D shapes: Defined by vertices, connecting lines, faces (2D shapes), and interior points, forming polyhedrons (e.g., cubes, pyramids, and tetrahedrons). Some shapes have curved surfaces (e.g., ellipsoids, spheres).

    1.5 Properties of Geometric Objects for Measurement

    • 2D shapes: Properties include sides and angles.
    • 3D shapes: Properties include faces, edges, and vertices.

    1.7 Math Basics

    • 1.7.1 Reading Numbers: Examples of reading numbers in their full form are provided, including some different variations in English pronunciation within these forms.
    • 1.7.2 Equations: Examples and descriptions of basic mathematical operations such as addition, subtraction, multiplication, and division are given. Power, raise to the nth power and basic formula operations are also covered.

    1.6 Location

    • Location describes the position of an object relative to other objects or the whole area.
    • There are absolute (positions relative to a place such as "in the middle") and relative references (positions relative to other objects using prepositions, "above", "next to").

    Exercises

    • Exercises: Examples relating the content learned in the study material to apply these concepts. Examples demonstrating correct English usage are offered along with an explanation of the mathematical formulae shown. Exercises to practice vocabulary and concept mastery are presented.
