We love Montessori, especially for Math. There are so many hands-on opportunity and this is the best way for my children (and most children) to learn. In this post, we will talk a lot about Montessori Math lessons, well, more specifically, we will be focusing on Montessori Math Subtraction Facts.

We will show you an activity that we did together to practice subtraction. Another thing I wanted to remind you of is that we are also including some free Montessori Math subtraction worksheets for you to download. We feel that they will make learning subtraction easier.

## Montessori Math Manipulatives

First of all, we love Montessori Math manipulatives! Rather than using just paper and pencil materials, they are the best because they make learning so much easier. Below, I am showing you some of the materials we used for this and other lessons. Many of them have many uses. Also, I just love the versatility of many Montessori Math manipulatives. The clear pouches are perfect for protecting papers, for making reusable with dry erase markers and they are double-sided.

## Montessori Math Subtraction Facts

This is the Montessori Math material used for this lesson:

**One Montessori Subtraction Strip Board****A Montessori Subtraction Equations and Differences Box**- Montessori Large Bead Frame
- Montessori Math Subtraction Template (free printable here)
- Dry Erase Pockets (optional)
- Pencil or
**thin dry erase markers** - Also, a table or 3×5′ rug

## Presentation Setup

Let’s begin with the setup. In the subtraction box, there is a board, a set of strips with numbers from 1-9 in blue and a set of strips with numbers 10-18 in red. Also, there is a set of 17 plain wooden strips. These have no numbers and go from the size of 1 square to 17 squares. Due to our material, we will use the floor for this work instead of a table. So have the child unroll the mat and place the board on the left.

The plain wooden strips are placed above the board, going from shortest at the top to longest at the bottom. The blue strips go to the right of the board, going from shortest at the top to longest at the bottom. Basically, build a stair with both the plain and blue strips.

## Subtraction Introductory Lesson

These Montessori Math lessons are simple. Just remember what the main purpose is for the students to memorize basic subtraction combinations. And the more they practice, the faster they will learn them. On the board, you will notice that the numbers 1-9 are blue and the numbers 10-18 are red. We will focus on subtraction 1-9.

For the subtraction facts, we use our **Montessori Subtraction Equations and Differences Box** because it is so easy to just randomly pick some out of the box. Begin with 18-9= by placing the blue strip with the 9 underneath the red 18 on the board. So, we start at the 18 and take away the 9. How many blank squares are left on the board for that equation? Nine! So 18 minus 9 equals 9.

## Let’s continue with more Montessori Math subtraction

17-9= would go like this: Take one plain wooden square and place it on the 18 on the board (see first picture above). Place the blue strip with the 9 on it below the 17. How many squares are left on the board? Eight! Simple, right?

Well, just to be sure, look at the second picture above. It is solving 15-9= by covering the 16, 17 and 18 with the plain wooden strip (3 squares’ worth) and placing the blue strip with the 9 under the 15. How many blank square are left to the left? Six. 15-9=6.

Since this activity has many way to go wit hit, you can decide to use the same blue strip to make all possible subtraction facts with it, such a 18-9, 17-9, 16-9, 15-9, 14-9, etc.

Our free printable comes with a subtraction template and numbers 1-18. You can print these our in black and white and** laminate** them or use a **clear pouch** for easy reuse. You can use the numbers included to make different subtraction equations or use thin dry erase markers.

I love this! We haven’t tried the subtraction board (still contemplating to get both the addition and subtraction) and this post is giving me more of the “go”. Thank you!
