The IM Math center kits are NOT worth… The IM Math center kits are NOT worth the money. The quality is poor and misinformation was given on their website and over the phone and they told me that I am wrong, their rep would have never said that. Save your money and spend the time to print on card-stock and laminate yourself. I highly doubt the $400 kit will even last a year.

I order a LOT from ETA Hand2Mind I order a LOT from ETA Hand2Mind. They have great prices - particularly for their Cuisenaire rods. Because I order in the quantities that I do (at least 100 C-rod sets a year), there's inevitably going to be some manipulatives that come in with some sort of flaw (but this is a small fraction). ETA is good about fixing these issues when they do arise and making things right. That, and their prices, are a big reason I keep coming back.

Great supplier of math manipulatives Easy online buying experience, followed up by shipping confirmations. In a recent purchase, when one item was unavailable, I was notified by email with a request to contact them about re-ordering. Items received were good quality and I'd definitely order again. The items leave their facility quickly but the biggest hurdle is getting through customs into Canada without delays and reaching a rural destination with postal delivery (none of which are the company's fault).

My product didn't arrive on time My product didn't arrive on time. No one notified me that it was in back order.
