My previous post on Multiplication using the Montessori Multiplication Bead Board has been very popular, and I’m so happy that many people find it useful. In this post, I’m sharing that using Bead Board is just one of the many ways of teaching Multiplication in a Montessori classroom. Another favorite of ours is the use of colored bead bars. This is usually introduced after the Multiplication Bead Board or the Charts (though I will share about the Multiplication Charts soon!). We’ve worked with several multiplication activities using the bead bars, but I will highlight the basic presentation in this post.   Again please note that this is based on a home setup.

Materials Needed
• Notebook
• Pencil
• Multiplication Chart 1
Age

For 6 years old and older.

Purpose

For hands-on activity in learning Multiplication using concrete materials like the Montessori bead bars. This will assist the child in memorizing multiplication facts that are essential in higher mathematics.

How to Teach Multiplication using Bead Bars

Tell the child that you will demonstrate Multiplication using the Montessori bead bars. Once the materials are placed on the table (or on the rug), ask the child to pick a number of her choice which you will use to present Multiplication. If this is their first time doing the activity, encourage the child to choose a smaller number. Our example in this post is bead bar 3 (pink). Pick the three-bead bars and place them horizontally in front of you. Say, “This is 3 one time. 3 times 1 is 3.”  Have your child pick the three-bead bar and place it vertically below the 3 bead bars. See the image below for the presentation.

The child records the result in the notebook.

Next, get two-three bead bars and place them horizontally beside the first bead bar. Say, “This is 3 two times. 3 times 2 is 6.” Have your child pick the six-bead bar and place it below the two bead bars. Continue working up to three ten times (3 times 10) with your child recording the results in his/her notebook.

Here’s the example end product of the multiplication table of 10:

On some other days, you can work with different numbers like the ones in the picture; here, my son was working with 5s.

Once your child has gotten used to using bead bars in Multiplication, he/she can add the arithmetic equations to help her memorize and prepare for abstract work.

Multiplication by Ten
When working with 10s, allow your child to explore and notice the pattern that multiplying by 10 is to just add zero after the multiplier. See the image below for a demonstration:
