Which letters are known to form tunnel shapes?

The letters that are known to form tunnel shapes are those that have arches or curves and connect from the top to the bottom, providing a visual representation resembling a tunnel. In this context, the set of letters h, m, n, and u exemplifies this shape. Each of these letters features a structure that includes horizontal lines connected by arches or vertical strokes, making them visually representational of a tunnel.

Understanding why these letters form tunnel shapes is beneficial in emergent literacy, as it can help young learners recognize letter formations and improve their writing skills. By identifying shapes within letters, VPK instructors can provide targeted activities that encourage students to practice these letters and enhance their fine motor skills, as well as their understanding of letter recognition.
