Input-Output Tables

Input and output tables are diagrams used to teach the basic concepts of functions. They are based on the rule of the function. When the table is filled in, it produces the pairs of coordinates that are necessary to construct the graph. The input is the value of x that is applied to the function. The output is the f(x), or the answer that is received as a result of putting x into the function.

Here is a link to a clear explanation with examples.

Weathering, Erosion, and Deposition

We are studying the slow changes to the Earth's surface. These processes include weathering, erosion, and deposition.

Weathering is the process of natural forces breaking down rocks into smaller pieces. Some of the causes of weathering include: moving water, ice, wind, plant root growth, burrowing animals, and temperature changes.

Erosion is the process which the broken pieces are transported, or moved, from one place to another. Some of the causes of erosion include: moving water, wind, glaciers (ice), and gravity (avalanches).

Deposition is the process of moved particles being deposited, or dropped off, in a new location. This process creates new land forms such as flood plains, deltas, sand dunes, and beaches.

Although we talk about weathering, erosion, and deposition as three separate processes, they often occur together. Over time, rocks are generally broken into smaller pieces (weathering), carried downhill (erosion), and deposited in a new location (deposition).

Personal Financial Literacy

Personal financial literacy is mainly used in connection with personal finance matters. Financial literacy often entails the knowledge of properly making decisions pertaining to certain personal finance areas like real estate, insurance, investing, saving (especially for college), tax planning and retirement. We apply this daily with our classroom economic system.

We specifically learned a few areas of personal financial literacy. We focused on:

• calculating profit in a given situation 
• determining the relationship between income, expense, and profit
• describing the purpose of financial institutions
• determining fixed expenses and variable expenses

Financial Institutions

The basic purpose of financial institutions include keeping money safe, borrowing money, and lending money.

Fixed and Variable Expenses

Fixed expenses are expenses that occur regularly and the amount does not change.

• car payment
• mortgage payment or rent
• insurance (health and car)
• housekeeper

Variable expenses are expenses in which the amount does change based on need or choice/want.

• electric bill
• water bill
• groceries
• eating out
• movies/entertainment

Here is a video that shows the difference between the two expenses:

Here are a couple of games to play to practice these skills:

Profit

Profit is the money that is made in a business after all the costs and expenses are paid. Profit is calculated by subtracting expenses (cost or payment for goods and services) from income (money earned or received): 

income - expenses = profit 

The calculations that we do depend on what information the question is asking us to find. There are times we are looking to find: 

• the profit:
• income - expenses = profit
• the expenses:
• income - profit = expenses
• or the income (revenue):
• profit + expenses = income

Here is a strip diagram that we use when calculating profit:

This helps us determine which operation to use to find the missing piece.
