CIA CIA Math & Numeracy Support 1 — Questions and Answers
Question 1: A student struggles with place value concepts. Which manipulative is most effective for an instructional assistant to use?
- Base-ten blocks (Correct answer)
- Flash cards
- Worksheets
- Number charts only
Correct answer: Base-ten blocks
Base-ten blocks provide hands-on, concrete representation of place value that helps students visualize ones, tens, and hundreds.
Question 2: When supporting a student who reverses numbers (e.g., writes 21 as 12), the CIA should first:
- Mark answers wrong without comment
- Use tracing and multisensory writing practice (Correct answer)
- Send the student to special education immediately
- Ignore it as a developmental phase
Correct answer: Use tracing and multisensory writing practice
Multisensory tracing practice helps students build correct number formation through kinesthetic, visual, and tactile pathways.
Question 3: A student cannot recall basic multiplication facts under timed conditions. The BEST support strategy is:
- Remove all timed activities
- Provide a multiplication reference chart as an accommodation (Correct answer)
- Have the student repeat facts aloud 50 times
- Skip multiplication and move to division
Correct answer: Provide a multiplication reference chart as an accommodation
A multiplication reference chart is a recognized accommodation that supports access to grade-level math content while fact fluency develops.
Question 4: When helping a student understand fractions, which instructional sequence is most appropriate?
- Abstract symbols first, then concrete models
- Concrete models, then pictorial representations, then abstract symbols (Correct answer)
- Memorize rules first, then apply to problems
- Skip fractions and focus on decimals
Correct answer: Concrete models, then pictorial representations, then abstract symbols
The concrete-pictorial-abstract (CPA) progression is a research-based approach that builds deep conceptual understanding of fractions.
Question 5: A student consistently makes errors when borrowing in subtraction. The CIA should:
- Have the student redo the same worksheet repeatedly
- Model the regrouping process step-by-step using base-ten blocks (Correct answer)
- Tell the student to try harder
- Move on to a new topic
Correct answer: Model the regrouping process step-by-step using base-ten blocks
Modeling regrouping with base-ten blocks makes the abstract borrowing process concrete and understandable.
Question 6: Which strategy best supports a student with math anxiety during problem-solving?
- Call on the student unexpectedly to build confidence
- Encourage estimation and allow multiple solution pathways (Correct answer)
- Focus exclusively on timed drills to build speed
- Require silent independent work only
Correct answer: Encourage estimation and allow multiple solution pathways
Allowing estimation and multiple solution pathways reduces pressure and builds confidence in students experiencing math anxiety.
