Ratios, expressions and equations questions
Question 1 · Ratios, expressions and equations
A sequence starts at 3. Each term after that is 3 times the term before it, minus 5. What is the 4th term?
Show the answer and why
Answer: C. 16
The terms are 3, 4, 7, 16.
Why a child might pick a wrong answer:
- A. 7 - applied the rule one time too few
- B. 43 - applied the rule one time too many
- D. -114 - subtracted before multiplying instead of after
Question 2 · Ratios, expressions and equations
Which expression means "4 less than 8 times a number n"?
Show the answer and why
Answer: D. 8n - 4
Translate the phrase in the order the operations happen; "4 less than 8 times a number n" is 8n - 4.
Why a child might pick a wrong answer:
- A. 8n + 4 - used addition instead of subtraction
- B. 8(n - 4) - grouped the subtraction inside the multiplication
- C. 4 - 8n - reversed the order of the subtraction
Question 3 · Ratios, expressions and equations
Solve for x: 7x - 3 <= 95
Show the answer and why
Answer: C. x <= 14
Add 3 to both sides to get 7x <= 98, then divide by 7 to get x <= 14. Dividing by a positive number keeps the sign the same.
Why a child might pick a wrong answer:
- A. x <= 92 - subtracts the constant instead of adding it
- B. x >= 14 - reverses the inequality sign when it should stay as it is
- D. x <= 98 - forgets to divide by the coefficient
The number system questions
Question 4 · The number system
What is (-5)^4?
Show the answer and why
Answer: C. 625
(-5)^4 means 4 factors of -5. An even number of negative factors gives a positive answer, so the value is 625.
Why a child might pick a wrong answer:
- A. 20 - multiplies the base by the exponent and ignores the sign
- B. -625 - always makes the answer negative
- D. -20 - multiplies the base by the exponent
Question 5 · The number system
Write 13/20 as a percent.
Show the answer and why
Answer: A. 65 percent
13/20 = 0.65 as a decimal, and multiplying by 100 gives 65 percent.
Why a child might pick a wrong answer:
- B. 153.8462 percent - divides the denominator by the numerator
- C. 33 percent - adds the numerator and the denominator
- D. 13 percent - reads the numerator as the percent
Question 6 · The number system
$600.00 is invested at a simple interest rate of 5% per year for 4 years. How much interest is earned?
Show the answer and why
Answer: B. $120.00
Simple interest is I = P x r x t = $600.00 x 0.05 x 4 = $120.00.
Why a child might pick a wrong answer:
- A. $1200.00 - moved the percent decimal one place the wrong way
- C. $30.00 - used one year only, forgetting to multiply by the time
- D. $720.00 - gave the total amount instead of the interest

Question 7 · Geometry
An isosceles triangle has an apex angle of 30 degrees. What is the measure of each base angle?
Show the answer and why
Answer: B. 75 degrees
The two base angles are equal and share 180 - 30 = 150 degrees, so each is 75.
Why a child might pick a wrong answer:
- A. 150 degrees - forgot that the remaining angle is shared between two base angles
- C. 30 degrees - assumed all three angles are equal
- D. 165 degrees - used 360 degrees as the angle sum
Question 8 · Geometry
A right triangle has legs of 6 cm and 8 cm. How long is the hypotenuse?
Show the answer and why
Answer: D. 10 cm
6^2 + 8^2 = 100, and the square root of 100 is 10.
Why a child might pick a wrong answer:
- A. 100 cm - added the squares but forgot to take the square root
- B. 2 cm - subtracted the legs
- C. 14 cm - added the legs instead of using the theorem
Statistics and probability questions
Question 9 · Statistics and probability
What is the mean of this data set? 42.5, 38.2, 51, 44.8, 39.6, 47.3
Show the answer and why
Answer: B. 43.9
Sum the 6 values (263.4) and divide by 6: 43.9.
Why a child might pick a wrong answer:
- A. 43.65 - reports the median instead of the mean
- C. 44.18 - drops one value from both the sum and the count
- D. 52.68 - divides by one fewer value than the set contains
Question 10 · Statistics and probability
What is the interquartile range of this data set: 5, 8, 12, 36, 44, 50, 54?
Show the answer and why
Answer: A. 42
The lower quartile is 8 and the upper quartile is 50, so the interquartile range is 50 - 8 = 42.
Why a child might pick a wrong answer:
- B. 36 - gave the median
- C. 50 - gave the upper quartile on its own
- D. 49 - gave the full range instead of the middle half
How these questions work
MAP Growth math is adaptive: every right answer makes the next question harder and every wrong one makes it easier, so the test settles where your child is working and most children get about a third of the questions wrong. A typical 8th grader scores 222 in math in the fall and 229 in the spring on the 2025 norms.
Each question has one right answer out of four. Where our bank records it, the explanation also names the likely thinking behind each wrong answer: added instead of multiplied, forgot to carry, read the question too fast. That is the useful part. A wrong answer with a reason tells you what to practise; a wrong answer on its own only tells you it was wrong.

Ten questions are a taste, not a measurement. A child can miss one through a slip and get another by guessing, so read the pattern rather than the total: two wrong answers in the same skill area, for the same reason, say more than the score out of ten.
To see the whole picture, the full Point of Progress test does the same thing across math and reading & writing in about forty minutes: it adapts like MAP Growth, then reports every skill as strong or worth work and every wrong answer with the likely thinking behind it, and turns the gaps into a ten-week workbook.

Questions parents ask
Are these real MAP test questions?
No. NWEA does not share the questions in its tests, and anything sold as the real MAP questions is not. These are Point of Progress’s own questions, written in the same multiple-choice style and spread across the same kind of skill areas.
What is a good MAP math score for 8th grade?
On the 2025 norms the average 8th grader scores 222 in math in the fall and 229 in the spring. The full ranges, percentiles and the proficiency bar are on what is a good MAP score for 8th grade.
Will practising questions raise my child’s MAP score?
Knowing the format helps a child stay calm, which is worth something. What moves a RIT score is the skills underneath, so the useful step after a practice set is to work on the area where the wrong answers cluster, not to repeat more questions of the same kind.
Why does my child see questions above their grade?
Because MAP Growth is adaptive and not tied to a grade. It keeps raising the difficulty until your child starts getting questions wrong, so meeting harder questions usually means the earlier ones went well.
Is the MAP Growth math test timed?
No. MAP Growth is untimed, so there is no reason to rush. A child who slows down and checks each option usually does better than one who races, which is worth practising on the questions above.
