Ladder Method

How Do Ladders Help With Math???

I can't tell you enough how much I love the Ladder Method!  To be honest, I didn't like it at first.  Believe it or not, a few years ago was the first time I learned it! Like many of you, I was hesitant to use it because it was a new concept to me and it wasn't how I was taught. Learning new ways to do something can be hard for people to accept and use. Even though I wasn't a big fan of it, I taught it to my students and showed them how to use it.  We used it as a strategy, but primarily used listing factors as our go-to solution.  

I was determined to like it, because other teachers really liked using it.   How did I get over my frustrations with it?  I practiced, practiced, and practiced some more!  Now when I use the Ladder Method, it makes so much more sense.  I love that you can use this one tool to figure out 3 different concepts!  We only used it for SIMPLIFYING FRACTIONS today.   Once you get the hang of it, it is a real game changer and saves some time.     Here is a video that explores this concept step by step!  

Something you really need to know is your PRIME NUMBERS.  It helps you get a good start when using the Ladder.  You really need to use the smaller ones.  It is good to have the first 5 or 6 
memorized. 

 You also need to know your MATH FACTS!  If you struggle with knowing your basic math facts fluently, then practice, practice, practice!  You want it to be automatic.  

CCSS.MATH.CONTENT.5.NF.A.1
Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum or difference of fractions with like denominators. 

For example, 2/3 + 5/4 = 8/12 + 15/12 = 23/12. (In general, a/b + c/d = (ad + bc)/bd.)
