Coordinate plane examples:
Students will become familiar with the x/y coordinate plane, both from the perspective of plotting points and interpreting the placement of points on a plane.
Decimals and Fractions on a Number Line:
We're mixing it up by placing both fractions and decimals on the same number line. Great practice because you need to move effortlessly between the two.
The Cartesian Coordinate System:
The Cartesian Coordinate system, formed from the Cartesian product of the real number line with itself, allows algebraic equations to be visualized as geometric shapes in two or three dimensions.
Pre-Algebra - Fractions and Rational Numbers:
The first fractions used by ancient civilizations were "unit fractions." Later, numerators other than one were added, creating "vulgar fractions" which became our modern fractions. Together, fractions and integers form the "rational numbers."
Pre-Algebra - Whole Numbers, Integers, and the Number Line:
Number systems evolved from the natural "counting" numbers, to whole numbers (with the addition of zero), to integers (with the addition of negative numbers), and beyond. These number systems are easily understood using the number line.
Students will be able to see examples of addition of integers while watching a short video, and practice adding integers using an online quiz.
