Well, I was talked into it. I finally put together a price list using IFIT and Alison's Montessori.
Caveats:
 These prices are based on full price, not sale price and assume you are making the list amount possible, buying everything new that you possibly can, and have no access to discounted used materials (and you don't want to call any nearby Montessori schools and ask about picking up any of their old materials).
 In other words, this is the MOST you could possibly pay.
 Prices do not include shipping (which could be free)
 Neither IFIT nor Alison's carries everything listed in the Keys of the Universe albums, but between the two of them, everything is offered.
 Exception: I could not find the fractions charts or the Story of Numbers charts  however both of these are available at Keys of the Universe online support (discussion community) or Garden of Francis.
 The prices are awful on some items, which is your encouragement to make a bit more yourself! (wooden hierarchical material comes to mind!)
 There are some things that still need to be handmade  either they are offered with the KotU online support (discussion community), will be soon, are offered at Garden of Francis, or are very easy to make from the album writeups.
 Some things transition UP from Primary (ages 36)  there is a chart in the file regarding which items you may have already purchased that can be deducted from the main chart.
 Most items can be resold when you are done (after going through ALL your children!) for at least half their original cost, sometimes closer to 80%.
 All materials are for multiple children  these are not onetime uses.

 Materials Price List
Caveats: This is not entirely a complete comparison, because both
companies do not sell all the same materials. And you might purchase the least
expensive of any given option at each one of them. I also have not calculated
if you bought all available at one and filled in with the other. Consider this:
some of this you will find cheaper used; or you can indeed make it yourself.

cannot yet write the numerals. Pull the bead bars from the Decanomial Bead
Bar Box. (need for elementary)
·
Golden beads (45 units and tens, 45 wooden hundreds and 9
wooden thousands) – need for elementary anyway
·
Teens and Tens boards (can be made on paper for the
purposes of remediation), with beads from the Decanomial Bead Bar Box and
golden units – but if you have them for another primary child, then use the
regular ones.
·

each number is stored together (all three ones together, all three twos
together)
Wow.
ReplyDeleteThat was a lot of work! At my stage in the game it is a RELIEF to look through all that and realize I already own it all, LOL. In my head I always think of geometry as part of math so I DO have some geometry materials outstanding. I'll probably be ordering them soon and I keep thinking, "wow, I'll be done ordering materials." Of course, there will always be things I want from ETC and such, but still. I don't know if I'll EVER make those geometry charts. Yuck. Kids can make them.
I have been meaning to ask you a question from the OTHER point of view. I am going to be selling a bunch of things soon. I am giving my shelves the old stink eye and thinking about what can get out of the way. Most things are an obvious yes or no. However, I've been eyeing up my 1000 cubes and 100 squares. I have 45 of each. AFTER we've done group division in elementary do I still need those. I am happy to keep them if you think I'll use them. I just keep looking at them and wonder if I'll be glad to have them in a year or two to revisit something. Wanted your opinion. Same with the 100 board. Will I find a use for it if I have it or should it go. (I keep thinking "multiples" but I think the paper boards are more useful for that.)
I was so nervous doing this because I thought the numbers would scare people away! Maybe it still will, but the response so far has been one of relief. Yay!
DeleteExponential notation still uses the golden beads (not all 45 cubes though ;) ); after that you should be good. I should check the adolescent album though... if you decide to go down that route you might come hunt me down and say "you told me!" ;)
100 board should be good to go.
Quick glance at the adolescent  I don't see the golden beads listed.
DeleteYou've given me an idea though!
I need to get on with some sewing and stampmaking, so by midafternoon, I hope to have posted scans of the materials list pages (3) from the adolescent album  and will post in the discussion community. I can't provide the whole album, but I think I am ok with sharing the materials list so everyone knows what to keep if they continue with Montessori!
Oh that would be great! I do plan on getting that adolescent algebra/math album in the future. I would love to know what I need to hang on to so that I don't sell off things I need. I'll look over that exponential notation album page(s) and see how far away we are and how much I might want to keep. I'd love to get some of these wooden number cards off my shelf too.
DeleteThank you Jessica for this...and WOW, that was a TON of work. A TON. Goodness. I am feeling like MBT here knowing that this year we have basically collected all the Montessori materials that we'll be needing through the end of KotU. (now it is on to all the other things we need.) I actually felt like I spent WAY more on materials than this, but I guess it could have been the primary stuff that makes me feel like this. There is a TON TON of that.
ReplyDeleteThis list also goes to show how much is made by the guide. It is amazing to me how any of us find the time. True dedication perhaps.
Thank you again for putting this together! MBT I want to see your new elementaryonly shelves when you are done with your reorg!
Wow, that must have been a ton of work. So kind of you to share this!
ReplyDeletewhoa, as I take a big gulp! Will I ever be able to come up for air from material making?? lol
ReplyDeleteIt truly does come to an end  or at least becomes a TINY trickle. ;) I am also a FIRM believer in the child creating materials as well  either by own design or as an assistant.
Delete:)
Wow. So much material! Just for math! I absolutely understand sequential learning and really love that but, man! As an absolute beginner, it's highly intimidating.
ReplyDeleteAnd for that  I wish I could make it look as good as it actually is!
DeleteThis is 6 years of materials (some of which can be used in primary; and some of which is also used into adolescence)  many of the materials are used again and again and again (you'll note where the symbol "" is)  only where a price is listed is there an actual material to purchase or make. The only new things for the last chapter ("Other Topics") for example is the negative snake game and the powers of 2 cube ;)
So  it IS better than it looks ;)
