Free Montessori Style Addition Worksheets (Double-Digit Addition)

When my kids were first learning to do double-digit addition, I found some Montessori math worksheets that worked extremely well for them.  They could follow the color scheme and also there was plenty of room for them to write in the numbers. I wound up making numerous sets for them.  I thought I would make a new set in a fall theme for those of you with kids just delving into this new skill!

The first four worksheets require no regrouping (ie. carrying).  Kids just practice adding the numbers in the same columns. Two sheets add tens and ones; two sheets add tens and tens.  The second four worksheets require kids to regroup (ie. carry) a number to the second (blue) column.

These addition worksheets are FREE to download. Just click the link or the picture below!!  Enjoy! ~Liesl

P.S. A few years ago after I shared these sheets, someone informed me that these are not “Montessori” math sheets.  I had gotten these types of problems off of a website that called itself “Montessori” years ago so I made the assumption that they were… but I am not trained as a Montessori teacher.  I just make things that work for my kids. Hopefully, they work for your kids too!  :) ~Liesl
