Adding and subtracting negative fractions and decimals (rational numbers), part 1
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.
