Dear Parents: Sept. 2004

I am looking forward to teaching math and science to your son/daughter this school year as well as being his/her homeroom teacher. The students will need the following things daily:

- a binder (with rings) only one or two subjects per binder please.

- a homework note book, a pencil, ruler, and eraser.

- their Science textbook

- At some point in the year they will also need a calculator, graph paper, and a compass set.

The evaluation scheme for math is as follows for each term:

Tests 30% Homework 15%

*P*roblem *O*f the *W*eek 15% Quizzes 35%

Organization (Preparation for class, organized scribbler) 5 %

Each Monday the students are given a challenging mathematical or logic problem. They may discuss the problem together but their final answer must be
their own. On Friday the students are to hand-in their *POW*.

Their evaluation form for organization will be a scale ranging from 1 for poor to five for excellent on the following criteria: class participation, effort, work habits, organized scribbler, preparation for class and organization. This mark will be mutually determined by the student and teacher.

Extra help time will be in the mornings or noon hour but the student should make an appointment one day in advance in order to plan a suitable time.

We will be using a variety of texts on a daily basis as well as handouts. We will have the opportunity to use the software Understanding Math and we will try to practice on a regular basis our mental math strategies. The concepts to be studied in math are as follows:

Number Theory

recognize square roots, perfect squares from1 to 144 and their pattens

understand approximations of square roots

show and explain the meaning of negative exponents

write numbers in scientific notation and vice versa

compare and order negative fractions, decimals and rational numbers

represent percents as fractions and decimals and vice versa

solve problems using ratios and equivalent rates

**Operation Sense**

understand the order of operations with rational numbers

solve proportion problems using different strategies

compose and solve problems using estimation for percent

use percent increase and decrease in solving problems

add, subtract, multiply, and divide fractions and decimals using various strategies

add, subtract, and multiply algebraic terms

Patterns

use patterns to find unknown values

interpret linear and non-linear relations

construct and analyse (x,y) values and graphs

discover the relationship between graphs and their corresponding slopes and y intercepts

solve problems using the intersection of two linear equations

solve algebraic equations

compose and solve word problems with linear equations

Measurement

use proportions to solve problems with different units of measurement

solve problems using the appropriate metric unit

estimate the area of a circle

develop and use the formula for the area of a circle

examine patterns with area and perimeter of quadrilaterals and circumferences of circles

calculate the area of combined shapes

estimate and calculate the volume and area of rectangular prisms and cylinders

understand the Pythagorean Theorem

Geometry

examine patterns with three dimensional objects and polygons

understand how to draw reflections, rotations, and translations

enlarge or reduce geometric using equivalent ratios

Data Management

Communicate the difference between biassed and unbiassed sampling

formulate questions for investigation from relevant contexts

Select, defend, and use appropriate data collection methods

Construct a histogram, circle graphs, and other appropriate data displays and make inferences from them

construct A best-fit@ line for distribution data

construct A box and whisker@ diagrams to represent data

Determine medians, means and modes.

form conclusions based on graphs

Probability

Identify situations for which the probability would be near 0, 1/4, 1/ 2 , 3/4 and 1.

Solve probability problems using simulations and experiments.

Identify all possible outcomes of two independent events.

Compare experimental results with theoretical results.

Use fractions, decimals and percents as numerical expressions to describe probability.

In Science, we will have the following evaluation guidelines:

assignments 20%

labs 20%

homework 10%

quizzes 25%

tests 20%

participation/organization 5%

The units that will be studied are:

The Cell

- the history and use of the microscope

-unicellular and multicellular organisms

- the size and parts of the cell

- the cellular membrane and its role

-how the cell obtains its energy

- cellular respiration and reproduction

-cellular organization in plants and animals

- systems of the body and health

Fluids

-viscosity

- density

- floating and sinking

- pressure including water and air pressure systems

Light

- what is light?

-the electromagnetic spectrum

- reflection and refraction

- concave and convex mirrors

-concave and convex lenses

- the camera and the eye

- color

Water Systems

- water on our planet

- where does rain water end up?

- permeability and porosity

- wells and sources of water

- the water cycle

- water distribution

- pollution and acid rain

-oceans

-waves

-tides

-water and the climate

- life in the water and its importance to humans and the environment

Work and Energy

- what is work?

-simple machines (pulleys, inclined planes, and levers)

- efficiency

- mechanical advantage

- work and energy

-human diet and energy requirements

I look forward to this school year and I invite you to contact me at any time if you have any questions, comments or concerns. Also, please check out my website for homework, problems of the week, etc at http://ssdsbstaff.ednet.ns.ca/george11.
