- The identity properties of addition and multiplication, where adding/multiplying a number by the identity element (0 for addition, 1 for multiplication) does not change the number.
- The inverse properties of addition and multiplication, where adding/multiplying the inverse or opposite of a number results in the identity element.
- The distributive property, where a number outside parentheses distributes to each term inside.
- The zero property of multiplication, where any number multiplied by zero equals zero.

1i denseness of numbers lesson 2
This document provides instruction on demonstrating the denseness of rational numbers using decimals. It explains that denseness means there is always a number between any two other numbers. Students are guided to write numbers vertically in a chart with added zeros and identify all numbers between given values. Examples are provided of naming numbers between decimals like 2.4 and 2.39 or converting a mixed number like 4 1/2 to a decimal. Students are assigned a handout and enrichment activity to further explain denseness through drawings.
1i denseness of numbers lesson 1
Rational numbers are dense between any two rational numbers. There are an infinite number of rational numbers between any two rational numbers, no matter how close together they are. To demonstrate this, one can take any two rational numbers, like fractions or decimals, find their lowest common denominator, and then list all the rational numbers between their numerators using that denominator. This shows there are always more rational numbers that can be found between any two given rational numbers.
