Warm-up:  Factors & multiples review... on front board

Classwork:  Intro to Least Common Multiple (LCM) and Lowest common denominator (LCD), and how they assist us in adding & subtracting fractions. We also discussed answers to homework (pg 48)

Turned-in:    nothing

Homework:   Unit #4, page 58  + see below...

  • [*SPECIAL > ADD a 5th problem on the bottom of page 58:  "What is the LCD of the fractions that are shown in problems 1, 2, 3, and 4?" Another way to look at problem #5 is to think about... what common denominator might you use, if you wanted to use the LCD, when adding together 1/2 + 1/3 + 3/4 + 2/5 ??   Keep in mind that there is just ONE ANSWER for this question. ]
