This month the educational product we are recommending is a music CD.  The CD is Singin' in the Bathtub by John Lithgow.  You may be wondering what is so educational about a music CD.  Well, one of my favorite songs from my childhood is on this CD and it is great for helping children learn number sense.   John Lithgow Sings Inchworm

Lyrics: Two and two are four Four and four are eight Eight and eight are sixteen Sixteen and sixteen are thirty-two Inchworm, inchworm Measuring the marigold You and your arithmetic You'll probably go far Inchworm, inchworm Measuring the marigold Seems to me you'd stop and see How beautiful they are My own children quickly grew to love this song and ask for me to sing it to them almost every night.  I watched my children use this song to increase their understanding of numbers.  My four year old son will hold up and count his fingers as I sing the song.  My six year old daughter will use the song to figure out more complex problems quickly.  For example, she will say that since she knows that 8 and 8 are 16, then 8 and 9 must be 17. The whole CD is a lot of fun and you can hear excerpts from it here:   Singin' in the Bathtub
