The blackboard clock : device desk book for the primary teacher, for teaching pupils in first year and kindergarten grades how to tell time of day by the clock, and time drill.

A practical handbook for early‑year teachers, this guide shows how to turn a simple blackboard into a lively time‑telling tool. It walks educators through every step of building a large, foot‑diameter clock face, from drawing the circle to attaching durable hands made of tin, pasteboard, or pins. The instructions also suggest easy ways to add colour and even repurpose an old clock movement for extra realism.

Beyond construction, the book offers clear, child‑friendly explanations of minutes, hours, and the relationship between the two hands. It outlines a series of short, repeatable drills—pointing to hours, counting minutes together, and practicing “half‑past” positions—to keep young learners engaged. By combining visual aids with rhythmic counting, teachers can help kindergarteners develop confidence in reading both Roman and Arabic numerals on an everyday clock.
