NAEP Mathematics Framework (National Assessment Governing Board framework; not a CCSS-M/state standards test blueprint) — national

How the NAEP reports it

NAEP mathematics is organized by the National Assessment Governing Board’s framework, not by state standards. The current framework assesses Grades 4, 8, and 12 and uses five content areas, with item distributions and complexity levels specified in the official framework; it is a national assessment and not aligned to Common Core as a governing blueprint, though it reflects broadly modern school math expectations.

Blueprint & weighting

Published item distribution by grade and content area: Grade 4 — Number Properties and Operations 40%, Measurement 20%, Geometry 15%, Data Analysis/Statistics/Probability 10%, Algebra 15%; Grade 8 — Number Properties and Operations 20%, Measurement 15%, Geometry 20%, Data Analysis/Statistics/Probability 15%, Algebra 30%; Grade 12 — Number Properties and Operations 10%, Measurement and Geometry 30%, Data Analysis/Statistics/Probability 25%, Algebra 35%.

What is the probability of the spinner landing on a shaded section (5 of 8)? Give a simplified fraction.

P=favorabletotal=58=58P = \dfrac{\text{favorable}}{\text{total}} = \dfrac{5}{8} = \dfrac{5}{8}.

A histogram has bins 0-9: 4 values, 10-19: 7 values, 20-29: 5 values. How many data values are there in all?

Add bin frequencies: 4+7+5=164+7+5=16.

For two independent events, the probability of flipping two heads in a row: P(A)=12P(A)=\tfrac{1}{2}, P(B)=12P(B)=\tfrac{1}{2}. Find P(A and B)P(A \text{ and } B) as a simplified fraction.

Multiply: P(A and B)=12×12=14P(A \text{ and } B) = \tfrac{1}{2} \times \tfrac{1}{2} = \tfrac{1}{4}.

A bowl contains 44 lemons and 99 limes. One piece of fruit is chosen at random. What is the probability that the fruit is a lime?

There are 4+9=134 + 9 = 13 pieces of fruit and 99 are limes, so P(lime)=913P(\text{lime}) = \dfrac{9}{13}.

A number cube is rolled once. What is the probability of rolling an even number?

Three of the six faces (2,4,62, 4, 6) are even, so P=36=12P = \dfrac{3}{6} = \dfrac{1}{2}.

The whole numbers 11 through 2424 were each written on separate cards. Those 2424 cards were placed in a hat. One card will be randomly drawn from this hat. What is the probability that the card will show a number greater than 1515?

Numbers greater than 1515 from 11 to 2424 are 16,17,18,19,20,21,22,23,2416, 17, 18, 19, 20, 21, 22, 23, 24, giving 99 favorable outcomes: P=924=38P = \tfrac{9}{24} = \tfrac{3}{8}.

A standard six-sided number cube is rolled twice. What is the probability of rolling a 44 on the first roll and an even number on the second roll?

P(4 on first roll)=16P(4\text{ on first roll}) = \dfrac{1}{6} and P(even on second roll)=36=12P(\text{even on second roll}) = \dfrac{3}{6} = \dfrac{1}{2}. So P(both)=16×12=112P(\text{both}) = \dfrac{1}{6} \times \dfrac{1}{2} = \dfrac{1}{12}.

Four data sets record the number of pages read in four or five sessions. Which set has the least standard deviation?

Set A:
4,8,12,164, 8, 12, 16
Set B:
6,8,10,12,146, 8, 10, 12, 14
Set C:
7,8,9,10,117, 8, 9, 10, 11
Set D:
2,6,10,14,182, 6, 10, 14, 18

Set C has mean 99 with consecutive values from 77 to 1111, each only one or two units from the center, giving the smallest standard deviation, about 1.41.4. Sets A, B, and D spread farther from their means.
