According to Gettman, Link is in Period Five for his math works. I'm separating the works into the

threads that MBT uses: linear counting, operations, memorization, fractions, and story problems/equation formats. I'm also using MBH which is organized similarly to MBT's threads.

So in period five that includes the following works:

__Linear Counting__

Formation of Complex Numbers (with cards)

Introduction to Teens

Introduction to Tens

Counting - 100 and 1,000 Chains, 100 Board and skip counting

__Operations__

Collective Exercises (Addition, Subtraction and Multiplication)

Stamps (Addition, Subtraction and Multiplication)

Dots

__Fractions__

Concept and Quantity

In period six that will include:

__Operations__

Collective Exercises (Division)

Stamps (Division)

__Memorization__

Addition and Subtraction Snake Games

Addition and Subtraction Strip Boards

Multiplication Tables

Multiplication Bead Board

Finger Charts

__Fractions__

Advanced work with Fractions

Period seven:

__Memorization__

Unit Division Board

Division Charts

Small Bead Frame

Hierarchical Material

Large Bead Frame

Now I just have to figure out what materials I need to purchase to get through these three periods.

__Period Five__
Already have

golden bead material, teen and ten boards, stamps.

Need Counting chains, 100 Board and fraction material.

__Period Six__
Snake games

Addition and Subtraction Strip Boards

Multiplication Tables

Multiplication Bead Board

Fraction material

__Period Seven__
Division Board

Division Charts

Small and Large Bead Frames

Hmm. I just configured what

MBT says is the minimum bead material, but I'm not exactly sure what those things are used for. I'm assuming that the first three items in the list will cover counting chains and snake games. It just seems like a lot for just those works, but I know they have extensions as well.

Here is what I'm looking at from IFIT for $596, free shipping. (If I just do Periods five and six, its $510, so I might as well get Period Seven while I'm at it.)

Adena, Montessori Outlet and Alison's were all about $650, but Adena includes a cabinet. So I could save $188 at Adena.

This does not include

*any* of the fraction material. It's

*so* expensive! I'm not exactly sure what I need for fractions. It seems like I could get away with

*just* the metal fraction circles for $56 from Adena. ($85 from IFIT, but I hear IFIT's are better quality.)

Since I'm a little ahead of the game this time, I don't have to rush into buying anything. I'll probably wait until the new year to do this purchase.

I never used the control chart for my 100 board. But it's only $2 so why not, right?

ReplyDeleteWe use our bead chains A LOT. It's more than just the skip counting, but rather the concept of squaring and cubing that will play big in elementary. Don't forget, you are also getting all of the colored squares and cubes with that and you'll use those a lot in elementary too.

The decanomial bead bar box is used for the first memorization of multiplication work. It is used a ton right from the outset of elementary as well.

My advice is to NOT get the metal fraction circles if your budget is truly tight. As soon as you are doing mixed fractions you need more pieces than the circles provide and you will be buying:

You can do all of the fraction work with these if you want. It just won't be a slick...you won't be able to trace the triangles...you won't have them in "a circle" when you do the equivalence work. You could stick them in your Montessori protractor if you have one:

The squares divided into triangles (fractions) could be done with a printable. I think I'm going to use them later in elementary but haven't gotten that far yet.

I want to warn you. There is a recent thread on Playschool6 in which several people are reporting unusable materials and poor customer service from iFit. I've done business with them ten times or so with NO PROBLEM and several other say the same. However, there is a chance they have new management or new ownership or something. Someone reported beads missing off of their new bead frames and the customer service saying "you get what you pay for." Don' t know if it's true or not, but you should know.

I'm glad to hear that there will be more use of the beads in elementary. I guess I should have figured that, I just haven't gotten to the elementary level yet :)

DeleteI thought about getting just those cut-out labeled fraction circles, but I was a little afraid of missing the visualization of the full circle. I do like this geometric board, which is sorta like the protractor you linked. http://www.adenamontessori.us/details.php?did=1455

It's $22 instead of $56. It's not that I mind spending the extra on the metal fractions, I'm just not sure how much more use we'd get out of them as opposed to the cut-out ones. (our metal insets are hardly ever used.) I could get the cut-out circles and the geometric board for the same price as the metal set, and I think they'd be more useful. Anyways, it sounds like maybe I've got a good list this time and I should be good until we enter elementary...? I don't know how much Adena's prices fluctuate, but I'm tempted to go ahead and order while they are cheaper than IFIT. Thanks for your input, it is always appreciated!

Well, they'll still get the visualization of the full circle if you put the cut-outs together into a full circle. I would just put some shelf liner down on a tray and lay out full circles of each kind for a while. You will use the fraction circles in elementary too, so buying the metal ones won't be a waste.
