### Lesson Plans

Below you will find a sample set of lesson plans aligned with the new N.S. Math 9 curriculum.
Each lesson is titled by Unit/Topic followed by a brief overview of the lesson objectives.

Unit 1
Square Roots and Surface Area
Lesson 1: Squares and Square Roots
Introduces students to the concept of squaring and taking the square root of a number. A direct connections with a square's area to its sides is developed to aid in the understanding of the operations of squaring and taking the square root. Students can access a screencast reviewing several of the core concepts at any point throughout the lesson.

Lesson 2: Square Roots of Non-Perfect Squares
Students will explore more closely the concept of square roots, but will specifically look at the square roots of non-perfect squares.

Lesson 3: Surface Area exploration
Students will explore the construction of a variety of 3D composite shapes through the 3D construction software program 3D Sketchup. Begin the lesson with a brief introduction to the sketchup program and work with students through an introductory activity, before setting them up on the task of building and analyzing a 3D model of a doghouse.

Unit 2 Powers and Exponent Laws Lesson 1: Powers & Exponents Introduction
Students will explore a fundamental application of exponents by exploring the measurement of 2 inches as the sole dimension for length, area, and volume.
Students will create and publish diagrams for lengths, areas, and volumes using the app ShowMe. Cube-a-links may be used as a supplemental resource, but are not a requirement.

#### Exponent Example

Lesson 2: Applications of Exponents
Students will congregate in pairs and select an application of exponents that exists in today's working world. Students are to prepare a presentation (with several necessary components) about their application of choice using Google Slides. Upon completion, each pairing will present their work to the class, thus exploring a variety of exponent applications.

Unit 3 Rational Numbers Lesson 1: Adding Fractions Introduction
Using Fraction Blocks and Sketchup 3D design software, students will learn about representing fractions visually/concretely, and the fundamentals of adding/subtracting fractions. Students will create a digital model of solving a fraction addition problem, and publish their results to the Sketchup 3D database.

#### SketchUp Frations

Lesson 2: Applications and Sport
Students will make connections between their favourite sport and the mathematics that goes into playing the game, keeping statistics, building the playing space, constructing the equipment, etc..
By analyzing the mathematics in basketball, students will see a variety of connections from measurement to statistics.

#### Math and BBall

Unit 4
Linear Relations
Introduction to Linear Relations
Students explore patterns in a variety of contexts and come to define a linear relationship between variables. Students are introduced into the multiple representations of relationships that we will be using throughout the unit.

#### Linear Relations

Linear and Non-Linear Relations
Students explore a variety of patterns and relationships, and learn to distinguish between linear and non-linear phenomena. Students further develop their ability to represent relationships in a variety of ways including tables of values, graphs, equations, and through the english language.

Linear Applications
Students explore the application of linear relations in a variety of contexts. Students will focus on a simple business that applies a linear model to determine its revenue. Students will use this model to help them project revenue for this business and begin to develop their own ideas for applying linear relationships to business analysis.

#### Linear Applications

Unit 5
Polynomials
Intro to Polynomials
Students will explore the basic mathematical skills which will be applied throughout Unit 5. Students will view a series of online tutorials through khan academy, before taking a self-assessment and moving on in preparation to apply their knowledge.

Polynomials Area Project
Using polynomial algebra and basic measurement mathematics, students will engage in a project whose goal is to determine the entire area of a (hypothetical) mall floor. Students will use this area to determine the total cost of buying/laying tile.

Unit 6
Linear Equations and Inequalities
English to Math
Students explore the relationship between the english language and the mathematics used to represent it. Students come to learn that there are often different interpretations in written or spoken word, however there can only be one interpretation of mathematical language.

Single Step Equations
Students will view a series of tutorial videos working through the steps to solve single-step equations. Students will use the app ShowMe to demonstrate their knowledge of solving single step equations to share with the class.

Solving Single-Step Equations 1 Screencast
Solving Single-Step Equations 2 Screencast
Solving Single-Step Equations 3 Screencast

Unit 7 Similarities and Transformations Indirect Measurement
Students will use their height and their shadow to solve for the height of unknown objects around the school-yard. Students will be engaged in the process of using similar triangles to solve indirect measurement problems. Be sure to do this activity on a nice sunny day!

Reflections
Students will explore the concept of reflections and lines of symmetry through the use of a variety of online interactive programs. A sufficient number of classroom/personal digital devices is required to run.

Scale model of School
Students will break into small groups and embark on a project to create a full scale model of their school. First, students sketch a scale model of a room they've been assigned. Secondly, they create a digital 3D model of their component using SketchUp 3D construction software. Thirdly, students piece together all of the different components created by the different groups in the class.

#### School Model

Symmetry
Students explore the concepts of reflective and rotational symmetry through a number of interactive online applets. Students engage in an activity analyzing symmetry of the letters of the alphabet before getting artistic and using rotational symmetry to create their own artwork.

Unit 8 Geometry Circle-Properties Guide
Students will use the online platform of Google Slides to create a Math guide that will include all of the circle geometry properties outlined for the Unit. Each entry in the guide must include well-labelled diagrams, written explanations, and an application.

Unit 9 Probability and Statistics Probability and Gaming
Students explore a number of games played at a typical casino or fair, and analyze the probabilities associated with 'winning' the game. Students come to the conclusion that the odds are not in the player's favour, and set out to create their own game with similar odds.

Statistical Argument
Students explore the 'use' of statistics to help prove an argument, from either side. Students will play the role of lawyer (mathematically inclined) and try to prove a difficult argument by selectively using statistics, and representing data in such a way as to prove the point on their agenda.

Online Polling
Students will using online polling software PollEverything to create and run a 10 question survey with their class. Students will analyze the pros and cons of surveying in such a manner, and will explore some different biases that could arise from such a survey style.
