Competency 002 of the Core Subjects EC–6: Mathematics (902). The competencies TEA lists, how they are tested and practice questions with explanations.
40 questions on the real 70-minute clock, with a score by competency group and an explanation for every answer.
Or start the free Number Concepts and Operations drillSummarized from the TExES Core Subjects EC–6 (391) preparation manual, Section 3: exam framework, Competency 002. The grouping of competencies into drill sets is ours.
Expect computation with whole numbers, fractions and decimals, place value and rounding, and questions that show a student’s algorithm and ask what error or property it shows. TEA lists the competencies without weights, so our practice test spreads its questions evenly across them.
Answer each question, then open the explanation.
Question 1
Which equation shows the distributive property?
Answer: A: 6 × (10 + 3) = 6 × 10 + 6 × 3
The distributive property multiplies a sum by multiplying each addend: a(b + c) = ab + ac. The other equations show the commutative, associative and identity properties.
Question 2
Which number is prime?
Answer: C: 29
29 has exactly two factors, 1 and 29. 21 = 3 × 7, 27 = 3 × 9 and 33 = 3 × 11.
Question 3
Which expression is equal to 2/3 ÷ 1/6?
Answer: D: 4
Dividing by a fraction is the same as multiplying by its reciprocal: 2/3 × 6/1 = 12/3 = 4. It also makes sense as "how many sixths are in two-thirds?": four.
Question 4
A class needs to estimate 398 × 21. Which estimate is most reasonable?
Answer: C: 8,000
Round 398 to 400 and 21 to 20: 400 × 20 = 8,000. The exact product is 8,358.
