Quiz over Factoring, Prime Factorization, LCM and GCF

Students took a quiz in class today that covered factoring, prime factorization, GCF and LCM.

Tonight's Homework: None! Enjoy the long weekend.

LCM and GCF Review

Students were given most of the class period to sharpen their skills on determining the LCM and GCF of different pairs of numbers. Some review problems on finding the prime factorization of numbers was also included.

Tonight's Homework: Finish both sides of the pink worksheet you started in class today.

Reviewing LCM, GCF and Factoring

We spent most of the period working together to answer some questions related to how a person might use the GCF or LCM in a real-life situation. Students completed most of the problems assigned on the handouts, and were instructed on which problems to complete for homework.

Tonight's Homework: Complete Lesson 4.4 if you did not do it last night. Finish the Road Trip problems, the LCM/GCF table, and two of the six problems on the tan worksheet.

Determining the Least Common Multiple of Pairs of Numbers

Our last lesson of this unit centers on finding the lowest number that two (or more) numbers go into evenly. This is called the LCM, or least common multiple, of the numbers. I like to think of it as the lowest common multiple. Be sure to look over Lesson 4.4 before starting on your homework problems if you missed class today.

Factor Review

Wow! Five absentees in one day--I hope you are all okay. Today, we took some time to review what we've learned this week. We focussed on factoring, prime factorization, factoring monomials, and finding the greatest common factor of pairs of numbers.

Tonight's Homework: None. Enjoy your weekend!

Simplifying Fractions

Factoring numbers and finding factor pairs of a given number can be helpful when trying to simplify a fraction. We can also simplify fractions by looking for a common factor. The number of times you need to simplify a given fraction depends on whether you can quickly figure out the greatest common factor of the pairs of numbers. Be sure to read lesson 4.3 to see how to simplify fractions that include monomials.

Finding the Greatest Common Factor

Now that we now how to factor a number, we can look at pairs of numbers and determine whether they share any common factors. For those pairs that share common factors, we can look at the list and see what the largest shared factor is, and this is called the greatest common factor (GCF). Sometimes the two numbers only share one factor (1). When this is the case, we say the numbers are relatively prime.
