✅ BATCH 1 – QUESTIONS 1 TO 100
1. A teacher asks you to help a small group of students read a short story. One student struggles with
the word “remarkable.” Which strategy should you use first to help the student decode the word?
A) Tell the student the word immediately
, Page 2 of 81
B) Ask the student to look for smaller words inside “remarkable”
C) Have the student skip the word and continue reading
D) Write the word on the board and define it
Answer: B – Encouraging the student to find familiar chunks like “mark” or “able” builds decoding skills
and independence, which is more effective than immediate correction.
2. A third-grade student writes, “The dog runned fast across the yard.” Which grammatical error is
present?
A) Incorrect verb tense
B) Missing subject-verb agreement
C) Run-on sentence
D) Incorrect pronoun case
Answer: A – “Runned” is an overregularization of the past tense; the correct form is “ran.” This is a
common developmental error in young writers.
3. You are monitoring a math center where students measure objects using inch rulers. One student
places the ruler starting at the “1” mark instead of “0.” What should you say?
A) “That is wrong. Start at zero.”
B) “Show me where the end of the object touches the ruler.”
C) “Let me do it for you.”
D) “Why didn’t you watch the demonstration?”

Answer: B – Guiding the student to self-correct by focusing on the endpoint encourages problem-solving
and understanding of measurement principles.
4. A teacher asks you to read aloud a passage about the water cycle. Which of the following best
demonstrates appropriate reading fluency?
A) Reading very slowly with frequent pauses
B) Reading with correct pacing, expression, and accuracy
C) Reading loudly but with many mispronunciations
D) Reading quickly without any expression
Answer: B – Fluency includes accuracy, appropriate rate, and prosody (expression), which supports
comprehension for listeners.
5. A student writes, “Their going to the library later.” Which word should be corrected?
A) Their
B) going
C) library
D) later
Answer: A – “Their” indicates possession; the correct word is “They’re” (they are). This is a common
homophone error.

6. During a math lesson on fractions, a student says, “I don’t get why 1/2 is bigger than 1/3.” Which real-
world example would most likely clarify this?
A) Draw two circles divided into 2 and 3 parts
B) Compare sharing a pizza between 2 vs. 3 people
C) Multiply both fractions by 6
D) Write both fractions as decimals
Answer: B – A pizza-sharing analogy connects fractions to a concrete, relatable experience, making the
abstract concept of unit size more understandable.
7. You are helping a student who reads “The boy went to the store” as “The boy goed to the store.”
Which skill does this error most directly affect?
A) Comprehension
B) Decoding
C) Morphology (past tense formation)
D) Sight word recognition
Answer: C – The student understands the past tense concept but overapplies the regular “-ed” rule,
indicating a morphological error, not decoding.
8. A teacher gives you a list of 10 spelling words. She asks you to dictate each word in a sentence. Which
of the following sentences best supports spelling of the word “separate”?
A) “Separate is a word.”
