    Young Math Books invite children to explore relationships that are basic to their environment and introduce them to mathematical language that will enable them to express their ideas about the world in which they are growing up.
    The books have been out of print for 30-40 years. Here is the list of the books compiled by Julie Brennan of Living Math. You can find some of them online when people scan them for their kids or their math clubs.
    Available Online
    These files were created for use in families and family math clubs. There's not enough demand to justify reprinting, and finding these books in libraries is getting harder every year.

    Full List
    3D 2D 1D Adler, David Geometry, measurement, volume/area. Very readable
