How to solve
This quiz mixes questions from different lessons, like a real test. Read each question carefully: the lesson name in front tells you what kind of problem it is. Check your answers, then practise the lessons where you made mistakes.
Example
Number & Shape Patterns: What number comes next? 12, 18, 24, 30, ___
Answer: 36

💡 Each figure adds a new row of 3 tiles, so Figure 4 has 4 rows of 3: 4 × 3 = 12. Figure 4 has 12 tiles.
✓ Correct!
Not quite. The answer is
💡 Each figure adds a new row of 3 tiles, so Figure 4 has 4 rows of 3: 4 × 3 = 12. Figure 4 has 12 tiles.
💡 How to solve: Number & Shape Patterns
Find the rule: see how much each number changes (for example, add 4). Then keep using the rule to find the next numbers. In a growing shape pattern, count how many tiles are added each time and keep adding them.

💡 One ray is on 0 of the inner (red) scale. Read the other ray on that same scale: 100. So the angle is 100°.
✓ Correct!
Not quite. The answer is
💡 One ray is on 0 of the inner (red) scale. Read the other ray on that same scale: 100. So the angle is 100°.
💡 How to solve: Measuring Angles with a Protractor
Line up the center of the protractor with the vertex and one ray with 0. Use the scale that starts at 0 on that ray, and follow it to where the other ray crosses. If the angle opens from the left side, read the outer scale; from the right side, read the inner scale. If neither ray is on 0, subtract the two readings.

💡 A line of symmetry folds a shape into two halves that match exactly. A square folds into matching halves up and down, side to side, and along both diagonals: 4 lines.
✓ Correct!
Not quite. The answer is
💡 A line of symmetry folds a shape into two halves that match exactly. A square folds into matching halves up and down, side to side, and along both diagonals: 4 lines.
💡 How to solve: Geometry: Lines & Symmetry
Perpendicular lines meet to make a right angle (90°). Parallel lines never meet and stay the same distance apart. A line of symmetry folds a shape into two matching halves, so count every way you could fold it.

💡 The perimeter is the distance all the way around, so add all four sides: 8 + 8 + 8 + 8 = 32. (Or 2 × (8 + 8) = 32.) The perimeter is 32 yards.
✓ Correct!
Not quite. The answer is
💡 The perimeter is the distance all the way around, so add all four sides: 8 + 8 + 8 + 8 = 32. (Or 2 × (8 + 8) = 32.) The perimeter is 32 yards.
💡 How to solve: Area & Perimeter Formulas (Unknown Sides)
Area = length × width, and perimeter = 2 × length + 2 × width. To find a missing side from the area, divide: 48 ÷ 6 = 8. To find a missing side from the perimeter, halve the perimeter and subtract the known side: 30 ÷ 2 = 15, and 15 − 6 = 9.

Not quite. The answer is
💡 ∠ABC is made of the two smaller angles ∠ABD and ∠DBC, so add them: 50° + 80° = 130°.
✓ Correct!
Not quite. The answer is
💡 ∠ABC is made of the two smaller angles ∠ABD and ∠DBC, so add them: 50° + 80° = 130°.
💡 How to solve: Adding Angles & Finding Missing Angles
When an angle is split into two smaller angles, the parts add up to the whole: 35° + 50° = 85°. To find a missing part, subtract the known part from the whole. A right angle is 90° and a straight angle is 180°, so the missing part is 90 − the known part or 180 − the known part.

∠ABD = 90° and ∠DBC = 30°. What is the measure of ∠ABC?

💡 One angle, 140°, is more than 90°, so it is an obtuse triangle.
✓ Correct!
Not quite. The answer is
💡 One angle, 140°, is more than 90°, so it is an obtuse triangle.
💡 How to solve: Classify Triangles by Angles & Sides
By angles: a right triangle has one 90° angle, an obtuse triangle has one angle greater than 90°, and an acute triangle has all three angles less than 90°. By sides: equilateral means all three sides are equal, isosceles means exactly two sides are equal, and scalene means no sides are equal.

💡 90° is exactly a square corner, so it is a right angle.
✓ Correct!
Not quite. The answer is
💡 90° is exactly a square corner, so it is a right angle.
💡 How to solve: Angle Measurement
Compare the angle to 90°. Less than 90° is acute, exactly 90° is right, between 90° and 180° is obtuse, and exactly 180° is straight.

💡 Use the first box beside it: ? × 30 = 600. 600 ÷ 30 = 20. Check: 27 = 20 + 7.
✓ Correct!
Not quite. The answer is
💡 Use the first box beside it: ? × 30 = 600. 600 ÷ 30 = 20. Check: 27 = 20 + 7.
💡 How to solve: Multiply 2-Digit Numbers with an Area Model
Split each number into tens and ones (34 = 30 + 4, 27 = 20 + 7). Multiply to fill each box: 20 × 30, 20 × 4, 7 × 30 and 7 × 4. Then add the four partial products: 600 + 80 + 210 + 28 = 918.

💡 A line segment is straight and stops at two endpoints. So the answer is line segment.
✓ Correct!
Not quite. The answer is
💡 A line segment is straight and stops at two endpoints. So the answer is line segment.
💡 How to solve: Points, Lines, Line Segments & Rays
A point is an exact location. A line goes on forever in both directions (arrows on both ends). A line segment has two endpoints. A ray has one endpoint and goes on forever in one direction. Two rays with the same endpoint make an angle. Parallel lines never meet; perpendicular lines meet at a right angle.
