That's a great question! While we recognize the tremendous value fonts such as D'Nealian present for learning writing (as well as being a precursor to cursive), we also recognize that for most of the children who use our blocks, a standard font they are already familiar with builds upon their existing letter knowledge since most children's material today are not in pre-cursive fonts. As our reading blocks are not only strictly used in Montessori circles, we chose a standard "child-friendly" font to allow children from any background or educational philosophy to benefit from using our phonetic reading blocks.
