Number Roots Mono, Bi, Tri and Cent
Written by Adi Ackerman, Head Teacher
"Number Roots Mono, Bi, Tri and Cent" is written for 6th Grade (Ages 11-12), and it covers Common Core L.6.4.B. If your student is a year younger but already steady here, the page still works. You may just need to read the instructions out loud. And if they are older and Greek and Latin roots never quite stuck, this is a short review rather than busywork.


6th grade vocabulary worksheet: write the number behind the root in 14 words like tripod and millennium, then tell what each means. Answer key included. Part of our Greek and Latin roots collection. Aligned to Common Core standards.
How do I use this worksheet?
Start with one root set, such as Greek Roots Graph, Phon, Photo and Tele, and keep the root box visible while students work. Use Greek and Latin Roots Review after the single root sheets to check what stuck.
What students will practice
- Students will name the number each root stands for in words like bilingual and quadrilateral.
- Students will see that cent and milli can mean 100 and 1,000 or 1/100 and 1/1,000, as in centimeter.
- Students will define 14 words, from unicycle to triathlon, using roots for 1 to 1,000.

Can I use this Greek and Latin roots worksheet for homeschool or classroom?
⌄
Yes, both. We made it for 6th Grade Greek and Latin roots, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.
How do you use a root to define a word?
⌄
Find the part of the word you know, recall its meaning, then check the guess against the sentence. In Use Roots to Define Unknown Words, a pedometer that showed 9,000 steps fits ped, foot, and meter, measure.
Do the roots worksheets include writing?
⌄
Yes. Greek Roots Graph, Phon, Photo and Tele ends with 3 sentences to write, Build Words From Roots asks for 10 words and their meanings, and Latin Roots Aud, Vid, Voc and Mit asks for three words on each root web.
Are the science words hard for 6th graders?
⌄
Greek and Latin Roots in Science Words splits 12 words like photosynthesis, hydrology and barometer into two roots each. The root box gives every meaning, so students can define the words from the page.
