Not exactly Numeracy, but too good not to share, there is a website called We Give Books. It is exactly what it sounds like. There is a selection of digital books that you can read (alone, with a child, with your class) and once you are finished you will be asked to input your e-mail (so the site knows you are an individual, real person) and they will donate a book to a child that needs it.
Here is a link to the website: We Give Books.
Today we read Goodnight iPad, a fun parody of the classic Goodnight Moon. Check out the site!!
