1What is the ratio of 12 red marbles to 18 blue marbles in simplest form?
A.2 : 3
B.3 : 2
C.4 : 6
D.2 : 5
Explanation: To write the ratio in simplest form, divide both numbers by their greatest common factor (GCF). The GCF of 12 and 18 is 6. Dividing 12 by 6 gives 2, and dividing 18 by 6 gives 3, resulting in 2 : 3.
2A grocery store sells 3 boxes of cereal for $15.00. What is the unit rate per box of cereal?
A.$3.00 per box
B.$4.50 per box
C.$5.00 per box
D.$6.00 per box
Explanation: To find the unit rate, divide the total cost by the number of boxes: $15.00 / 3 = $5.00 per box.
3What is 45% expressed as a fraction in simplest form?
A.9/20
B.4/5
C.9/10
D.45/50
Explanation: Percent means out of 100, so 45% is written as 45/100. Simplify by dividing both numerator and denominator by their GCF of 5: (45/5) / (100/5) = 9/20.
4In a class of 30 students, 18 are girls. What is the ratio of boys to total students in simplest form?
A.3 : 5
B.2 : 5
C.2 : 3
D.3 : 2
Explanation: First, find the number of boys: 30 total - 18 girls = 12 boys. The ratio of boys to total students is 12 : 30. Simplify by dividing both by 6 to get 2 : 5.
5What is 25% of 80?
A.15
B.20
C.25
D.30
Explanation: Convert 25% to a fraction (1/4) or decimal (0.25). Multiplying 0.25 * 80 or 80 / 4 gives 20.
6A car travels 120 miles in 2 hours. What is the unit rate in miles per hour?
A.50 mph
B.55 mph
C.60 mph
D.65 mph
Explanation: To calculate the speed in miles per hour, divide total distance by total time: 120 miles / 2 hours = 60 mph.
7Which ratio is equivalent to 3 : 4?
A.6 : 7
B.8 : 10
C.9 : 12
D.12 : 15
Explanation: Multiply both terms of the ratio 3 : 4 by the same non-zero integer, 3. 3 * 3 = 9 and 4 * 3 = 12, giving the equivalent ratio 9 : 12.
8A recipe calls for 2 cups of flour for every 3 cups of sugar. How many cups of flour are needed for 12 cups of sugar?
A.6 cups
B.8 cups
C.9 cups
D.10 cups
Explanation: Find the scale factor for sugar: 12 / 3 = 4. Multiply the cups of flour by this scale factor: 2 * 4 = 8 cups of flour.
9A store sells a 6-pack of juice bottles for $4.50 and a 10-pack of the same juice for $7.00. Which pack is the better buy and by how much per bottle?
A.6-pack, by $0.05 per bottle
B.10-pack, by $0.05 per bottle
C.10-pack, by $0.10 per bottle
D.Both packs cost the same per bottle
Explanation: Find unit price for 6-pack: $4.50 / 6 = $0.75 per bottle. Unit price for 10-pack: $7.00 / 10 = $0.70 per bottle. The 10-pack is cheaper by $0.75 - $0.70 = $0.05 per bottle.
10A cyclist travels at a constant speed of 14 miles per hour. How far will the cyclist travel in 3.5 hours?
A.42 miles
B.45.5 miles
C.49 miles
D.52.5 miles
Explanation: Distance = Speed * Time. Multiply 14 miles/hour * 3.5 hours = 49 miles.

About the SD Math Grade 6 Exam

The South Dakota Mathematics Assessment for Grade 6 is the state's annual summative assessment measuring 6th-grade students' mastery of South Dakota Content Standards in Mathematics. Administered online via the Smarter Balanced computer-adaptive system, the assessment tests ratio concepts, unit rates, percentages, dividing fractions by fractions, integer arithmetic, absolute value, exponents, algebraic expressions, 1-step equations & inequalities, triangle/polygon area, surface area nets, and statistical measures (mean, median, IQR, MAD). Please note: This 100-question practice bank is an English-language multiple-choice question (MCQ) study adaptation created by OpenExamPrep to help 6th-grade students practice core math standards in an accessible study format.

Assessment

Two components: a computer-adaptive test (CAT) and one performance task (PT) containing 4-6 items.

Time Limit

Untimed. SD DOE's published estimate is 2 hours for the CAT plus 1 hour for the performance task (about 3 hours total), taken during the spring window.

Passing Score

No pass/fail score. Four achievement levels are reported: Level 1 (standard not met), Level 2 (nearly met), Level 3 (met - the state proficiency benchmark), and Level 4 (exceeded).

Exam Fee

Free for South Dakota public school students. (South Dakota Department of Education (SD DOE))

2Understand unit rates and ratios by converting comparisons to simplified fractions or unit prices in real-world contexts.
3Practice integer arithmetic and absolute value on a number line to avoid sign errors when combining positive and negative numbers.
4Get fluent in applying the distributive property both to expand expressions like 4(x + 3) and to factor out common factors like 12x + 18.
5Memorize geometry formulas for the area of triangles (A = 1/2 * b * h) and parallelograms (A = b * h), and practice decomposing complex shapes.
