In this chapter we will start working with adding and subtracting fractions with like and unlike denominators. We will learn to estimate with benchmark fractions and mixed numbers. Adding mixed numbers may often incorporate the skill of changing improper fractions in the sum into mixed numbers and then combining the whole number part with the mixed number part. Subtraction of mixed numbers may often incorporate the skill of renaming the mixed number in the minuend in order to have a larger fractional part to subtract the subtrahend's fractional part. Again, estimation can be used to check for the reasonableness of your answers. We will use pencil and paper math for the most part, but we will explore the use of the fraction key/mixed number key on the calculator. Enjoy the learning!!!
