Do you use the ladder method in middle school or elementary math, to find GCF, LCM, or for any other math concepts? If you haven't had the chance to use the ladder method (or the upside down birthday cake method, as some call it), I highly recommend it. Ways to Use the Ladder Method As you can see in the anchor chart (sorry it's not as pretty as some!), math students can use the ladder method for:
Benefits of Using the Ladder Method1) What I really love about this method is that the process is the same for each use; the outside numbers are just used differently. I love the fact that the continued use of the ladder method (for various math concepts) leads middle school math students to make greater connections between numbers.....and finding factors seems to come more easily. 2) In addition to helping math students find GCF and LCM, using the ladder method helps students see the relationships between numbers more clearly. It's very easy to see what factors the numbers have in common and how those factors 'contribute' to the LCM or GCF. Ladder Method for FactoringWhen I started using the ladder method for factoring, students picked up the factoring concept MUCH more quickly than when I hadn't used it. The steps to use the ladder method for factoring are: 1) Put the expression into the ladder. 2) Take out the common factors, one at a time (common factors go outside the ladder, then divide each number in the expression by that factor and put the quotient below the numbers in the ladder. Repeat until all common factors have been 'removed.') 3) Multiply the numbers on the left of the ladder  these are the GCF and go outside the parenthesis in the factored expression. 4) Put the numbers at the bottom of the ladder into the parenthesis. The short video below demonstrates how to factor a simple expression. Ladder Method ResourcesSeveral years ago, I wrote a guest post about the ladder method on the Minds in Bloom blog, so if you're interested in reading more, check it out here. I shared a ladder method folditup in my guest post, but you can also click the button below, if you'd like to download it. Ladder Method Doodle NotesI've also created a fun Doodle Notes page to help students with the Ladder Method! Select the button below to see the Ladder Method Doodle Notes on TPT. If you've used the ladder method before, I'm sure you understand why I love it:) If you haven't used the ladder method yet, I hope you'll give it a try! To Read Next:

Use the Date to Encourage More Math Thinking in
Middle and Elementary School Updated 5/2020
How Can You Use Math in Writing the Date?
In 2015, I started adding a little extra math into my classes, homeroom and last period (homeroom students again)  by using the date! I had done this years ago, but hadn't used the idea in a while, so I brought it back to my middle school math classroom in two ways How to Use Math With the Date, Method 1:
To include more math in the middle school class, use all the digits in the date to create an equation.
How to Use Math With the Date, Method 2:
The other way I used the date to include more math in the classroom was to write the date so students have to evaluate an expression for each number in the date.
It's been fun to see some students writing these in the corner of their notebooks during class! Others have asked to write their equations or expressions on the board during the last period of the day. Five Benefits of Using Math Dates
What I love about including math ideas is that they:

Where Can You Find Math Dates Created for You?
At this time, I post math dates at the beginning of every week on Instagram (always on Instagram) and Facebook (most weeks on FB), so if you'd like to use them, I hope you'll follow me on one of those platforms (if you aren't already).
I created Math Dates resources for you to use throughout the year  these have been published by individual months and as a yearlong resource on TPT. I've added nearly a year of dates for upper elementary math as well. How do you include more math in the middle school classroom?
