Well, I was talked into it. I finally put together a price list using

 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.

Notes on Remediation

·
Bead bars – if the child is not yet counting to 10 OR
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.
·
Stamp Game (need for elementary
·
Geometry materials: cabinet, solids, geometric solids –
need for elementary geometry

IFIT Notes:
Golden
beads:
If
you don’t need the trays and cups, purchase the following:
·
9 Wooden Cubes: $24
·
45 Wood Hundreds: $26
·
45 Ten Bars: $11
·
45 Units: $1.50
·
(if you buy the bead cabinet material from
here, pull a beaded cube and beaded hundred from the bead cabinet for needed
presentations; otherwise, add 1 beaded cube and 1 beaded square  beaded cube
is $25; set of 9 beaded hundreds is $26).
·
You’ll need to add your choice of number cards
as well; or cut your own cardstock and make your own. (printable on Keys of the
Universe)
Alison Notes:
·
With the golden beads, verify which decimal
cards and sizes you are getting; consider printing your own.

Mathematics Materials List
Main
Materials – it is best to read the album page while preparing or purchasing the
materials, so that details do not have to be repeated here and you can
immediately see what each piece will be used for when considering alternates:
·
Golden bead materials – 45 units, 45 tens, 45
hundreds, 9 thousands (no more)
·
Decanomial bead bar box (bars 110, 55 of each
bar) –
o
Athome: some presentations need just a few
more bead bars – you could make the 47 extra with pony beads or connected
Legos
o
ideal for classes: add bead bar box of 110
with a smaller quantity
·
Box of bead bars 19 (schools may want 25 of
these; homes do not need it at all)
·
Box of number cards: white set with 19, 0,
gray set with same (3 copies of each #)
o
Could be same box with operation signs and
dots for decimal points
o
Another section for blank tickets and pencil
o
Classrooms need 3+ boxes
o
Could store some parentheses in here
o
A tacklebox is ideal
·
Prepared tickets for various operations
·
8 sets of parenthesis (cut from cardstock)
·
3 sets of small decimal system cards, 1 –
3000, stored on a tray/basket
·
Pegboard (30 by 30 ideal; 25 x 30 if that is
all that is available)
·
Box of hierarchical pegs (green, red, blue –
could be cut down golf pegs)
·
Tables A, B, C, E (on paper for children to
use)
·
Wooden hierarchical material and corresponding
number cards (used in early work and in Powers of 10 later) – this is the
