Spring Math & Reading — Answer Key
Part A: Multiple Choice
Circle the best answer for each question.
1. A weather station recorded rain on 12 out of 30 days in April. What is the experimental probability of rain on any given April day?
A) 13
B) 25
C) 12
D) 35
The correct answer is B) 25. A weather station recorded rain on 12 out of 30 days in April. What is the experimental probability of rain on any given April day — the answer is 25.
2. A student recorded high temperatures of 55, 60, 65, 70, and 75 degrees over five spring days. What is the median temperature?
A) 60 degrees
B) 65 degrees
C) 67 degrees
D) 70 degrees
The correct answer is B) 65 degrees. A student recorded high temperatures of 55, 60, 65, 70, and 75 degrees over five spring days. What is the median temperature — the answer is 65 degrees.
3. A garden log shows that tulips bloomed on day 14, daffodils on day 10, and crocuses on day 6. If the pattern continues with 4-day intervals, which flower blooms next on day 18?
A) Roses
B) Lilies
C) Irises
D) The next flower in the pattern blooms on day 18
The correct answer is D) The next flower in the pattern blooms on day 18. A garden log shows that tulips bloomed on day 14, daffodils on day 10, and crocuses on day 6. If the pattern continues with 4-day intervals, which flower blooms next on day 18 — the answer is The next flower in the pattern blooms on day 18.
4. A class planted 40 seeds. After one week, 32 had sprouted. What percent of the seeds sprouted?
A) 60%
B) 70%
C) 75%
D) 80%
The correct answer is D) 80%. A class planted 40 seeds. After one week, 32 had sprouted. What percent of the seeds sprouted — the answer is 80%.
Part B: Fill in the Blank
Write the correct answer on each line.
1. The middle value in an ordered set of numbers is called the median.
The median is found by arranging all values from least to greatest and picking the one in the exact middle of the list.
2. To convert a fraction to a percent, divide the numerator by the denominator and multiply by 100.
Multiplying by 100 converts a decimal into a percentage because "percent" literally means "per hundred."
3. A repeating sequence in data, such as bloom dates every 4 days, is called a pattern.
A pattern is a predictable, repeating sequence in data that lets you forecast what comes next, like blooms appearing every 4 days.
4. Probability is always a number between 0 and 1, where 1 means the event is certain.
Probability ranges from 0 (impossible) to 1 (certain), so a value of 1 means the event will definitely happen.
5. If 12 out of 30 days had rain, the fraction 1230 simplifies to 25.
The fraction 1230 simplifies to 25 because both 12 and 30 can be divided by their greatest common factor, 6.
