FOR 4TH GRADE

NUMBER AND OPERATION is a common core content. Common core content means it touches K-12 students.

The State expected the 4th grade student to master how to write and read the coordinate of a point in a graph. The student must understand the Cartesian coordinate system. Which point is located at (3,5) ? First lesson to remember is to identify a point in the graph. The common practice is to give it a letter name small letter l or capital letter L. The second lesson to remember L(x, y) , every point follow the same rule ( x = 3, y = 5 ). It means the first number (3,5) is always your distance along x - axis in number line from origin 0. The second number (3, 5) is always your distance along y - axis in number line from origin 0. Finally the location of the point is the intersection of x = 3 and y = 5. Written in mathematical expression as L(3,5)

This is a Pre-Algebra, Measurement and Geometry early exposure .

Geometry, Measurement, and Algebra skills are needed in coding like in expert system supervised machine learning algorithm using software like MATLAB, Python, R, Javascript, C, and C++. This skill is most likely to be used in Excel spreadsheet or similar spreadsheet software in most business today.
