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 use their division skill in solving word problem. This is a Pre-Algebra early exposure where the student learn the skill in extracting quantitative relationship from word problem. For example, the quantitative word clue for the problem below is Jim spends the same amount each day. It means the student must do division, which they know already.

Pre-Algebra and Algebra are higher grade level mathematics that teaches student to analyze the question(s) to be answered, look for word clues, number sequence pattern, organize given information, determine how to represent the problem, and identify implicit and explicit assumptions that have been made.

Number and Operation and Algebra skill 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.
