Making Montessori--Fractions

I am going to start a new series about my experiences as I learn to make my own Montessori manipulatives. Fractions are the topic today because that is what I am working on with my oldest.

Fractions circles can be found here:

I printed out 2 sets of circles and 1 set of numbers. When you print out the circles, mark what they are because if you don't you'll get a mess. The ones beyond 1/5 are all about the same size and impossible to sort and mark later. I've just printed out a second round of these and am dumping the first set I printed because of this.

Lessons on fractions can be found here:
http://www.infomontessori.com/mathematics/fractions.htm

http://freemontessori.org/?page_id=17 Math album 1 has fraction material starting on page 112. This is a long album and full of information.

http://faculty.fullerton.edu/syen/mts/math/_link.htm For younger children, page down for fraction activities.

Activity cards for fractions:

So I put together a binder of the instructions, put the fraction circles in an envelope to be put in the front pocket and cut and put the fraction labels in another envelope. I also put the decimal lessons from the big math album in this binder but I have not added in the manipulatives I have made for decimals as yet.

Here is your fraction lessons and manipulatives.

Adding--I have decided to put each set of fractions in a different envelope within a file folder. I am hoping that this helps us to keep the pieces separate and make it easier to put the lessons together. This is one place where I could see that it would be worth it to spend the money and buy the wooden fraction puzzles.

We will be touching on fractions a bit this year - the basic ones, such as 1/2 and 1/4 - and I will certainly make use of these links.

Glad I could help. I am planning on posting about the other things I have made. I've got the beads, tens and teens, and am working on a grammar box.

I hope to have the links to the materials to print out and the lesson plans that show how to use them.
