Mathematics - Table of Contents

We focus on the Keys of learning - and when we do, children learn through their hands. 


Once a child has mastered the concept of 1-9, the concept of 0 and the basic idea of putting groups together and separating groups (adding and subtracting), they are ready to work with 4 digit numbers.

UPDATE: See a math topic missing? Browse our other Montessori Nuggets, as I have upcoming Nuggets on this topic; then post in comments and I'll reply with where it is found within the albums --- not all Mathematics topics are found in the math album ;)

Be sure to check the reaction boxes below this post - this provides me some feedback of what you'd all like to see!

  1. Excellent post. Thank you for putting it all into a concise outline. Hope to see more "Table of Contents" for other areas of study.

  2. More coming :) I am looking to do each one as a combination of primary and elementary to show the complete flow from one plane of development to the next.

    If you (or anyone) has a particular area you'd like to see addressed that would fit with the theme here, please let me know. In particular along the lines of "top questions for new Montessori parents or teachers - or those seeking information on Montessori". :)

  3. This is so useful post! Thank you!

  4. Still learning here... we started Montessori "late" (always parented in the 'style' but haven't formally homeschooled Montessori until my son was about 5 ish). Does that mean I'm destined to constantly catch up with him? Even now at 5.5 y.o. he resists academics (sitting down to read on his own and is still struggling with memorizing numbers - 0 thru 9 is pretty good, but is just now starting to get a handle on teens & up recognition). I'd like to continue Montessori, but I worry that if the tools I have will no longer work since he's out of the sensitive periods, I may need to seek out an alternative.

  5. By the end of your first year of elementary, it won't be "playing catch up" so much - you'll see :)

    There is a point where you have to let go of everything he COULD have had in primary because he is moving into the second plane and the quality of his needs change.

    At 5, they like humor, they like games. I had 5 and 6 year olds during my student teaching who were "behind" so to speak; I had them start over with the sensorial album and focused on the games - they ate it up! Especially when there was a little trick or catch for us all to laugh about in the end.

    For mathematics materials - the core materials continue into elementary (golden beads, colored bead bars, chains/cubes/squares, fraction insets); and while there is a remediation section, again, at some point he just moves on to the next thing and he will be totally FINE.
