Here is a worksheet on the Latin word roots bi and bin. They mean two and twice. But you already know that, and your students probably will before long as they work their way through this material.
Of course these are extremely productive roots in English, and this worksheet includes many of the most frequently used words containing bi or bin, to wit: biannual, bicameral (a useful social studies word), bilingual, bicycle, and bifocal.
If you find typos in this document, I would appreciate a notification. And, as always, if you find this material useful in your practice, I would be grateful to hear what you think of it. I seek your peer review.
