In this 7th grade math lesson, we first use the number line to solve some fraction addition subtraction problems that involve negative fractions. • Then, we solve decimal additions subtractions, again, involving negative decimals. They are solved using the same principles as in integer addition and subtraction. • Lastly, I explain a money-related problem that involves positive and negative decimals (money amounts), in the context of a bank account balance. • The focus of the lesson is adding and subtracting rational numbers (fractions decimals). In the 2nd part of the lesson, we continue with some more problems involving negative fractions. • Learn more 7th grade math with Math Mammoth Grade 7 Complete Curriculum at http://www.mathmammoth.com/complete/g...
