{Made For Learning} A Moveable Alphabet
Moveable Alphabets are one of the most important (and fun-to-use) tools in a Montessori-style schoolroom. At least, that’s how our family feels about them. And they are easy and fun to make at home. Here’s how::

Gesso, and two different colours of paint. I chose blue and red because they are more traditionally Montessori style (pink in place of red also works). You choose whichever colours you like.

Paint each letter with a coat of gesso and allow to dry. The gesso comes right off of the brush with warm, soapy water.

... and red for the consonants. Next, apply two coats of varnish. You will need to wait a minimum of one hour between coats.

A purpose-made or purchased box is best for storage, but something like this little box with a clasp will do for a time. You really do want something that will allow you to keep each letter separate... Like with like. I'll show you how to make a proper storage box in an upcoming tutorial.
Scrabble™ Tiles also make excellent upper case moveable alphabets – and it’s a great way to recycle! You can also purchase blank tiles from Etsy – purchase alphabet transfers in the scrapbooking supply section of your craft store. Simple varnish over the top, or apply a couple of layers of Mod Podge.
Resources:
Cut out wood letters available for just under $12 for each set of upper or lower case letters. I suggest 1/8″ thick baltic birch letters in Arial, (Garamond and Rockwell are also available) – 2″ tall by 2″ wide. {These are my favourite ones, but more expensive}
Cut wood letters sold in packs of 36 are available at Michael’s crafts (and probably at Hobby Lobby) for about $4/pack. I bought four packs.
Scrabble letters are available on Etsy, and eBay, and can also be found at neighbourhood yard sales, flea markets, and car boot sales.
