At A Glance
Many of our classroom calculators have a compatible overhead projectable model for teachers. Each unit is in the same manner as its convertional counterpart, except that it is equipped with a transparent screen. When placed on a standard overhead projector, the screen can be projected onto a screen or wall for the whole class to see. Several models have completely transparent bodies, so that students can see the key squences as you press them. Each model comes with a durable case for added protection.
