Yesterday went really well as the response that I got from each class was "wow, this is really easy." Multiplying fractions is simply multiplying across the numerator, and multiplying across the denominator. I created an outline that students filled out during our notes, examples, and practice.
Today, students were split into 6 "stations." Each station focused on a different skill that we have learned over the last week. The quiz tomorrow will be made up of questions from the stations. Below are the questions students saw in class today.
Station 1 – Simplifying fractions by finding the GCF
Pick 4 problems
Find the Greatest Common Factor of each fraction, then simplify
1.) 4/12 GCF = Simplified =
2.) 5/35 GCF = Simplified =
3.) 8/24 GCF = Simplified =
4.) 3/15 GCF = Simplified =
5.) 6/12 GCF = Simplified =
6.) 2/13 GCF = Simplified =
7.) 10/60 GCF = Simplified =
8.) 6/20 GCF = Simplified =
Station 2 – Simplifying fractions by prime factorization
Pick 4 problems
Simplify each fraction by finding the prime factorization of the numerator and denominator, cancel out any possible pairs, then write in simplified form
1.) 27/35
In prime factorization = Simplified =
2.) 16/18
In prime factorization = Simplified =
3.) 20/30
In prime factorization = Simplified =
4.) 64/ 120
In prime factorization = Simplified =
5.) 100/ 150
In prime factorization = Simplified =
6.) 42/56
In prime factorization = Simplified =
7.) 9/24
In prime factorization = Simplified =
8.) 10/36
In prime factorization = Simplified =
Station 3 – Converting improper fractions to mixed numbers
Pick 6 problems
Convert to an improper fraction, then simplify if necessary
1.) 24/9 =
2.) 21/10 =
3.) 15/5 =
4.) 34/6 =
5.) 53/10 =
6.) 8/3 =
7.) 90/25 =
8.) 34/50 =
Station 4 – Converting mixed numbers to improper fractions
Pick 6 problems
1.) 4 2/3 =
2.) 5 1/5 =
3.) 6 5/7 =
4.) 2 4/5 =
5.) 10 2/3 =
6.) 3 1/2 =
7.) 5 3/8 =
8.) 9 1/5 =
Station 5 – Multiplying fractions
Pick 4 problems
Write your answer as a proper fraction or mixed number
1.) 5 x 2/3 =
2.) 7 x 5/8 =
3.) 2 x 7/10 =
4.) 1/3 x 2/5 =
5.) 1/8 x 5/9 =
6.) 4/5 x 1/8 =
7.) 4 x 5/9 =
8.) 1/6 x 5/8 =
Station 6 – Word problems
Pick 3 Problems
HINT: “of” means Multiply
1.) When John asked Brent how much pizza he wanted for lunch, he responded by saying “1/2 of 1/2 of a pizza”. As a fraction, how much pizza did he want for lunch?
2.) There are 280 students in the sixth grade. 1/8th of them picked reading as their favorite subject. How many of them picked reading as their favorite subject?
3.) John broke a candy bar into 4 equal pieces. He ate 1/2 of one of those pieces. How much of the total candy bar did he eat? (Answer will be a fraction)
4.) Ryan told his teacher that he completed 1/3 of the 96 questions on his test. How many did he complete?
5.) When Ben asked Jarrod how many tacos he could eat, he replied with “nine halves”. How could he show this number as a mixed number?
6.) There are 50 states on the United States of America. As a fraction, 4/25 of the states begin with the letter “M”. How many states begin with M?
