This three-part, ten-page activity, entitled DISGUISED DIGITS, is a compact study of selected Greek and Latin base words that function in our vocabulary as NUMBERS. The first section, focusing on UNI--, BI--, and TRI--, begins with background information (see sample pages for full script) and flows into the identification of thirty-eight different words formed from these three word parts. The second lesson targets NINE MORE counting base words, including QUAD--, OCTO--, DEC--, and MONO--, and presents fifty of their descents now functioning as English terms. In the third portion, students use the base-word concept to write twenty programmed sentences with both real and created terms.
