One of Z’s (3 years old) Math work is the Montessori Hundred Board, along with a few other Montessori Math activities.
What is the Montessori Hundred Board?
It is simply a board with 100 squares (10 x 10 squares), that come with 100 number tiles that fit nicely. Some of them come with a control card too (this is basically a board/card with pre-printed numbers on it.)
It is worthwhile to note that some Montessori albums (curriculum) don’t list this material as part of the curriculum.
But Z found our 1-90 Bingo chip placement card and wanted to read every number on it. He was clearly interested in working on bigger numbers, and when I let him try the free iPad version, my instincts were correct because he loved it! So I decided to invest in this material. (To learn more about following the child, click here.)
How to use the Montessori Hundred Board
In the very early stages, a child would be asked to first match the number chips to the numbers on the control card. But Z seemed to be past this stage, and also he refused to work with the control card and wanted to work only with the blank squares.
He has already somewhat mastered the sequence of numbers 1-20, in fact he is already advancing to the stage where I’m working with him to place numbers in the right boxes when the numbers are given to him in a random order.
Here’s a written lesson for your reference.
Where we are with the Montessori Hundred Board lessons
1. I continue to reinforce his 1-20 number sequencing, using lesson extensions that have a greater challenge (and some fun too!)
2. Next, we will work with numbers 21-100 slowly. While he can name the numbers correctly while placing them in order, he does get the tens names mixed up. Also, if given a 21-99 number randomly, he will sometimes say the later number first (for example, he might say 28 as “eighty two.”) I think it’s OK at this stage and I’m not worried, I believe it’s all part of the learning, although we will continue to practise.
How to make / Where to buy the Montessori Hundred Board
Alternatively, you can DIY this very easily!
- Livable Learning has a free Montessori Hundred Board printable that is measured for scrabble tiles.
- Pinay Homeschooler simply cut out small squares of colored cardstock and wrote the numbers on! It still works brilliantly, and you can use it as a test to see how well the material is received and enjoyed before investing in a sturdier set that can last longer.
Notes / Observations:
This is one of those materials where I let him have a lot more exploratory leeway than some others. It is nice to just sit back and observe him realize by himself that the number 22 comes directly below 12, as an example. There is a lot of learning that can be absorbed just by “playing” with this material, so I let him be as free with it as he likes.
As Z grows older and more sophisticated with numbers, I know there will be many more activity extensions that we will be doing. I will share those when the time comes!
- Living Montessori Now has a compilation of 100th day activities, some of which incorporate the Montessori Hundred Board.
- Pinay Homeschooler has more advanced logic and analytics activity ideas for older preschoolers.
