The bead materials came from Neinhuis Montessori. The red sticks came from them as well a number of years ago. I am not sure if they are still made. The integer strips came from a company called Hello Wood. The variable skittles come from a company called Hands On Equations. The negative number strips that correspond to the colors of the bead bars were developed by Harvey Hallenberg, a long-time Montessori teacher and teacher trainer. The presentations are fillmed by Montessori Live teacher training program.

Thanks for the clarification~

Thanks for taking the time to let us know!

There are a number of Montessori materials companies that provide lesson plans for the curriculum. Our program uses Montessori Research and Development. A Google search for Montessori albums would get you there as well.

Thanks for the positive feedback!

We do not have expertise in Singapore Math, although my understanding is that this program also uses "manipulative.".

The numerals can be purchased from Neinhuis or Alison's Montessori. There are two sizes. I like the smaller size for the fractions and the larger size for whole numbers. The cut-out "holes" representing negative numbers are homemade from the craft foam pieces (I think that is what they are called) that can be purchased from a craft store.

I’m asking about the number line and the red lines. That represents the distance. Thank you

That material was available from Neinhuis Montessori.

Hi, The colored bead bars with holes are handmade from the colored craft foam you can buy at Michael's or a similar craft store. They are cut so that the holes are the same size as the colored beads to allow the student to place the colored bead bar on top of the holes. The length of the foam piece is the same as the beadier (including the wires so that the holes last, if that makes sense!) Thanks for your question. This material was initially developed by Harvey Hallenberg. I took my elementary training from him in the mid-nineties and have used these materials ever since! I hope that helps.

Thank’s so much! I love that idea/material, it makes so much sense! @@MontessoriLive

Sorry for the delay. I just posted presentation videos for this lesson today.

You are so welcome!

Any Montessori materials company. Look up Montessori geometric solids.

Hey Flavia, Are you referring to the automatic subtitles that KZbin does on videos? If so, then that's a setting that anyone can adjust based on their personal account.

We'll be uploading more videos like this in the future. So keep an eye out for them!

Search for "Montessori metal inset material" and links to both the paper and metal insets will appear.

It is possible to introduce these shapes to toddlers. At the 3-6 level, they are the first lesson in the study of geometry and can be introduced to children who are three years old. They are also used in the lower elementary level. .

@@MontessoriLive thanks for replying. I've read Dr. Montessori's material and a few other books, but I definitely don't really know what I'm doing. Do you have any videos on teaching 12 months- and 28 month olds? As well as must have learning materials for them?

@@isabellyshelly8276 Hi, Our programs focus on early childhood and elementary levels. Unfortunately, we do not have a program for the toddler level.

Glad you liked it!

Carolina Biological is a company that has great science supplies.

This material can be used simply to add to 10 as well. It is one of the very first lessons on addition. The child may not have mastered the teens.

You're very welcome!

Glad you think so!
