Addition Table

From here on students can go in most any order they choose. They can start with addition or with multiplication. They should imagine themselves on an elevator able to go up or down anytime they want, to find interesting floors to explore. NOTE: The addition table, like the other tables, goes up and to the right to link their patterns with graphing and further work with functions. They thus have a horizontal and a vertical axis that they use to build their rules. The best rules needed to build this table requires the use of “absolute” addressing. Normal or “relative” addresses are patterns that copy from one area of a spreadsheet to another. Absolute or fixed addresses refer to a specific or fixed cells. You can fix an address by column in a rule by putting a $ sign in front of the letter or in a row by putting a $ sign in front of its number. For example: = $J15 or =J$15, or =$J$15.
