STAAR EOG Reading TEST: Latin & Greek Roots, Prefixes & Suffixes

Mastering STAAR Reading Word Roots

This comprehensive STAAR EOG Reading TEST guide offers strategies for mastering Latin and Greek roots, prefixes, and suffixes to help students in grades 3 through 8 succeed on the Texas STAAR reading test. Rather than relying on simple memorization, the text emphasizes a four-step detective method—chopping words into parts, finding clues, using sentence context, and checking the results—while providing grade-specific master tables and memorable visual tricks. Additionally, the material includes helpful resources for parents and teachers, featuring daily routines, interactive games, and valuable connections to Spanish cognates for English language learners.

The Full-Stack Guide for Parents, Teachers, and Students — Grades 3–8

Reading Sage | Sean Taylor, M.Ed.

Part 1. The Big Picture (Read This First)

The Texas STAAR reading test never asks a child to recite a root list. It hands them a real passage, points at a hard word, and asks what it means. A child who can chop the word into parts, read the clues, and check them against the sentence gets the point. A child who memorized a flashcard but cannot use it in context does not.

Three truths that shape everything below:

1. The Texas standards (TEKS) name specific word parts for each grade. STAAR can only assess what the TEKS expect. The standards say “such as,” so the named items are examples, the floor and not the ceiling. This guide covers every named item plus a bonus set.

2. Word parts are a clue, not a dictionary. A root narrows the meaning to a neighborhood. The sentence tells you which house.

3. Meaning beats memory. Silly, sticky pictures stay in the brain far longer than plain definitions. Every word part below has one.

Timeline note. Spring 2027 is the last STAAR administration for grades 3–8. Under House Bill 8, Texas replaces it in 2027–28 with three shorter, adaptive tests (beginning, middle, and end of year). The TEKS word-part skills carry straight over, so this work is not wasted.

How these items usually look (modeled on how the TEKS are assessed; check TEA’s released tests for official samples):

• What does the word ___ mean as it is used in paragraph __?

• Part A: What does ___ mean? Part B: Which word part or phrase from the passage supports your answer?

• Which word part in ___ helps the reader figure out its meaning?

• Select the TWO words that contain a root meaning ___.

Part 2. The Standards Map

Grade	What the TEKS name	Origin mix
3	Affixes: im- (into), in- (not), non-, dis-, pre-, -ness, -y, -ful	Latin + Old English
4 (4.3.C)	Affixes: mis-, sub-, -ment, -ity/-ty. Roots: auto, graph, meter	Old English, Latin, Greek
5 (5.3.C)	Affixes: trans-, super-, -ive, -logy. Roots: geo, photo	Latin + Greek
6 (6.2.C)	Roots: mis/mit, bene, man, vac, scrib/script, jur/jus	Latin
7 (7.2.C)	Roots: omni, log/logue, gen, vid/vis, phil, luc, sens/sent	Greek + Latin
8 (8.2.C)	Roots: ast, qui, path, mand/mend, duc	Greek + Latin

Vocabulary for the whole guide: A root carries the core meaning. A prefix goes in front and changes the meaning. A suffix goes at the end and changes the job the word does (noun, adjective, and so on). Latin and Greek are the two ancient languages that gave English most of its academic words.

Part 3. The Root Detective Method: CHOP – CLUE – CONTEXT – CHECK

1. CHOP it into parts: prefix, root, suffix.

2. CLUE: say what each part means.

3. CONTEXT: read the sentence. Does it agree with your clue?

4. CHECK: put your meaning back in the sentence. Does it make sense? Cross out any answer choice that fights the root.

Worked example: transcontinental

• CHOP: trans | continent | al

• CLUE: across | big landmass | having to do with

• CONTEXT: “The transcontinental train runs from coast to coast.”

• CHECK: “A train that goes across the continent.” Yes.

Answer-choice trick: The root usually knocks out two choices. The sentence breaks the tie between the last two.

Part 4. Grade-by-Grade Master Tables

Each row gives the meaning, test-style words, and a silly, sticky memory trick. Say the trick out loud. Drawing it is even better.

duc vs duck	A real duck is not a leader. The test word will be conduct or educate.
mend (order) vs mend (fix)	recommend means entrust and advise. It does NOT mean repair again.
Fake affixes	dish, pretty, moment, cement, interest, mister look like they have prefixes or suffixes. They do not. Chop only when the leftover is a real word or root.

The TEKS say “such as,” so these common roots are fair game for context-based questions.

Root	Means	Word

rupt	break	erupt, interrupt (a ROUGH break: ERUPTion)

Part 7. The Spanish Bridge (Texas Superpower)

Most Latin-root words have a Spanish cousin called a cognate. For bilingual and ELL students this is a huge shortcut.

English	Spanish cousin
-ity (curiosity)	-idad (curiosidad)
-ive (creative)	-ivo (creativo)
-logy (biology)	-logía (biología)
bene (benefit)	beneficio, bien

Part 8. Practice Items (STAAR-Style)

1. (Grade 3) The campers were dissatisfied when it rained all weekend. What does dissatisfied mean? A. very pleased B. not pleased C. very hungry D. full of energy

2. (Grade 4) The mayor wrote an autobiography about her childhood. An autobiography is a book about a person’s life written by A. a machine B. a stranger C. that same person D. a scientist

3. (Grade 5) The transcontinental train travels from coast to coast. Transcontinental means A. under the land B. across a continent C. above the clouds D. around a city

4. (Grade 6, two-part) The town thanked the benefactor who paid for the new library. Part A: What does benefactor mean? A. a person who does good by giving help B. a person who builds libraries C. a person who writes books D. a person who sends mail Part B: Which phrase best supports your answer? A. the town thanked B. paid for the new library C. who D. new

5. (Grade 7) The translucent curtain let soft morning light into the room. The root luc helps show that translucent means A. completely dark B. lets some light through C. very heavy D. brightly colored

6. (Grade 8) The teacher worried about the students’ apathy toward the project. Apathy most nearly means A. strong anger B. great excitement C. lack of feeling or interest D. deep sadness

7. (Grade 8, select TWO) Which words contain a root meaning “lead”? A. conduct B. educate C. duckling D. mandate

Answer Key

1. B. dis- means not, so not satisfied.

2. C. auto = self, bio = life, graph = write.

3. B. trans = across, continent = land mass.

4. A, then B. bene = good, and “paid for the new library” shows the good deed.

5. B. trans = through/across, luc = light. The sentence confirms it.

6. C. a- = without, path = feeling.

7. A and B. duc = lead. Duckling is a baby bird, a trap. Mandate has mand = order.

Part 9. Parent Guide: 10 Minutes a Day, No Tears

Golden rule: Do not drill lists. Play with words.

Day	10-minute activity
Mon	Meet it. Read the sticky trick aloud together. Have your child make up a sillier one.
Tue	Hunt it. Find the root on signs, labels, apps, and books (vacancy, transport, photo, manual).
Wed	Chop it. Write three words on sticky notes. Slice each with a pencil line.
Thu	Teach it back. Your child is the teacher. You play the confused student.
Fri	Play it. A quick game from Part 11.

When your child is stuck on a test-style item, ask three questions: What part do you know? What does the sentence say? Does your meaning fit when you put it back in?

Dinner-table challenge: Use the Root of the Week in a real sentence at dinner. The family gets a point each time it is used correctly.

Part 10. Teacher Guide: The Five-Day Root Cycle

Day	Move
1	Introduce. Teach the root with its silly story and a gesture. Chant it.
2	Chop. Word sorts and word sums (script + ure = scripture).
3	Context. Short sentences with the word in use. Students underline clues. Add one STAAR-style stem.
4	Play. Root Rummy, Word Surgeon, or Root Tree (see below).
5	Prove. A three-question exit ticket, then students write one original sentence.

Tips that work:

• Spiral review. Mix in roots from earlier weeks. Mastery comes from return visits.

• Cross the curriculum. Science (photo, geo, therm, meter), social studies (jur, mand, omni), math (meter, geo).

• Multisensory. Sky-write the root, tap the syllables, act out the silly story. This helps dyslexic and ELL learners especially.

• Teach the Spanish cousin in the same breath.

• Model failure. Show a root that misleads (mis-/mit, duc/duck) so students learn to check context.

Part 11. Student Guide: Be a Root Detective

The Detective’s Oath: I will CHOP. I will find the CLUE. I will read the CONTEXT. I will CHECK my answer.

Five fast games:

• Root Charades. Act out the root. Your team guesses the word.

• Word Surgeon. Cut the word into pieces and label each piece.

• Silly Sentence. Use three words with the same root in one funny sentence.

• Root Tree. Draw a tree. The root is at the bottom, the words are the leaves.

• Beat the Clock. Write as many words as you can with a root in 60 seconds.

One-glance cheat sheet:

• Gr 8: ast star | qui rest | path feeling | mand/mend order | duc lead

Part 12. Sources and Notes

• Word-part lists come from the Texas Essential Knowledge and Skills (TEKS) for English Language Arts and Reading, as shown on TEKS Guide (teksguide.org) and Texas Gateway. Always confirm grade placement against your district’s TEKS resources, since the standards say “such as.”

• The STAAR-to-SST transition is described in TEA’s HB 8 assessment update presentation (Spring 2026) and reporting by the Texas Tribune.

• Practice items and sticky tricks are original to this guide.
