create scaffold support for 7th grade math: adding and subtracting rational numbers in 1 page, add the law of signs and graphs

This resource provides an introduction to rational numbers, which include integers, fractions, and decimals that can be expressed as fractions. It explains fundamental operations with rational numbers, specifically addition and subtraction, based on the signs of the numbers involved. For numbers with the same signs, it instructs learners to add their absolute values and keep the same sign. For numbers with different signs, it teaches the method of subtracting the smaller absolute value from the larger one and taking the sign of the larger number. Additionally, it includes examples using a number line model for clarity and offers guided practice problems for learners to solve, reinforcing the concepts presented.
