Previously Published Data 

1.) Students will use least common multiples to determine common denominators. The chart can be used by those who need it : 2/3 and 5/6; 3/8 and 4/5; 1/12 and 7/8; and 12/18 and 11/72. 


2.) Students can also use greatest common factors to reduce fractions to the lowest terms. The chart can be used by those who need it: 8/40; 7/35; 12/72; 10/100; 14/56; and 13/52. 
3.) Family Math has a factor game in which cards are numbered 1-100. They are distributed face down to the players. Players take turns holding up one of the cards. The other players write down as many matching multiplication factors as they can. Points are given for the correct factors.
 

Previously Published Data 

1.) Students will record and solve addition, subtraction, multiplication, and division problems with fractions in their Mathematics Journals. Answers will be reduced to lowest terms, and students will list the strategies they used to solve the problems and define the terms: multiples, factors, and divisors. They will discuss the use of a factors and multiples chart.
