Competency 004 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.

Expect area and perimeter of composite figures, volume of prisms, unit conversions, angle facts, transformations and points on a coordinate grid. 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
Two angles of a triangle measure 48° and 67°. What is the measure of the third angle?
Answer: B: 65°
The angles of a triangle sum to 180°: 180 − 48 − 67 = 65°. The value 115° is the sum of the two given angles.
Question 2
Which statement about every square is true?
Answer: D: It is both a rectangle and a rhombus.
A square has four right angles (so it is a rectangle) and four equal sides (so it is a rhombus).
Question 3
A triangle is flipped over a vertical line so that it faces the opposite direction. Which transformation is this?
Answer: B: Reflection
Flipping a figure over a line is a reflection. A translation slides a figure, a rotation turns it about a point, and a dilation changes its size.
Question 4
What is the area of a triangle with a base of 10 meters and a height of 6 meters?
Answer: B: 30 square meters
Area of a triangle = 1/2 × base × height = 1/2 × 10 × 6 = 30 square meters. A triangle is half of a parallelogram with the same base and height.
