Answer Key & Explanations

Line Plots · Grade 2 · Worksheet 3

  1. Liam collected 35 seashells at the beach. His sister Emma found 42 seashells. How many seashells did they collect altogether? Answer: 77 Solution: Identify the number of seashells Liam collected. Liam collected 35 seashells. Identify the number of seashells Emma collected.
    Full step-by-step solution

    Step 1: Identify the number of seashells Liam collected. Liam collected 35 seashells. Step 2: Identify the number of seashells Emma collected. Emma collected 42 seashells. Step 3: To find the total number of seashells, add Liam's seashells and Emma's seashells together. Total seashells = 35 + 42. Step 4: Perform the addition. First, add the ones place: 5 + 2 = 7. Then, add the tens place: 3 + 4 = 7. So, 35 + 42 = 77. Step 5: State the final answer. Altogether, they collected 77 seashells.

  2. Mrs. Johnson's class measured how many centimeters tall their bean plants grew. The measurements were: 24 cm, 32 cm, 24 cm, 40 cm, 32 cm, and 24 cm. How many bean plants were exactly 24 cm tall? Answer: 3 Solution: 24 cm, 32 cm, 24 cm, 40 cm, 32 cm, 24 cm. 24, 32, 24, 40, 32, 24. We need to count how many plants were exactly 24 cm tall.
    Full step-by-step solution

    Let's go step-by-step. We are given the measurements of bean plants: 24 cm, 32 cm, 24 cm, 40 cm, 32 cm, 24 cm. Step 1: List all measurements in order as given: 24, 32, 24, 40, 32, 24. Step 2: We need to count how many plants were exactly 24 cm tall. Step 3: Go through the list one by one and count the occurrences of 24 cm: - First measurement: 24 cm → count = 1 - Second measurement: 32 cm → not counted - Third measurement: 24 cm → count = 2 - Fourth measurement: 40 cm → not counted - Fifth measurement: 32 cm → not counted - Sixth measurement: 24 cm → count = 3 Step 4: Final count: We found 3 measurements of 24 cm. Therefore, the number of bean plants exactly 24 cm tall is 3.

  3. 17 + 9 = ? Answer: 26 Solution: Add the ones place: 7 + 9 = 16. Write down the 6 in the ones place and carry over the 1 to the tens place. Add the tens place, including the carried-over 1: 1 (from 17) + 1 (carried over) = 2.
    Full step-by-step solution

    Step 1: Add the ones place: 7 + 9 = 16. Write down the 6 in the ones place and carry over the 1 to the tens place. Step 2: Add the tens place, including the carried-over 1: 1 (from 17) + 1 (carried over) = 2. Step 3: Combine the tens and ones: 20 + 6 = 26. The answer is 26.

  4. Liam collected 45 seashells at the beach on Monday. On Tuesday, he collected 32 more seashells. How many seashells did Liam collect in total? Answer: 77 Solution: Liam collected 45 seashells on Monday. On Tuesday, he collected 32 more seashells. We need to find the total number of seashells collected over both days.
    Full step-by-step solution

    Step 1: Understand the problem. Liam collected 45 seashells on Monday. On Tuesday, he collected 32 more seashells. We need to find the total number of seashells collected over both days. Step 2: Identify the operation. To find the total when combining two amounts, we use addition. Step 3: Write the addition expression. Total seashells = Seashells from Monday + Seashells from Tuesday Total seashells = 45 + 32 Step 4: Perform the addition. First, add the ones place: 5 + 2 = 7 Next, add the tens place: 4 + 3 = 7 So, 45 + 32 = 77 Step 5: State the final answer. Liam collected 77 seashells in total.

  5. Make a line plot showing: 9, 9, 12, 12, 12, 15, 15, 15, 15, 18, 18, 18, 18, 18 Answer: 18 Solution: List each number and count how many times it appears. 9 appears 2 times 12 appears 3 times 15 appears 4 times 18 appears 5 times The number that appears the most is 18, because it has 5 X's on the line plot.
    Full step-by-step solution

    Step 1: List each number and count how many times it appears. 9 appears 2 times 12 appears 3 times 15 appears 4 times 18 appears 5 times Step 2: The number that appears the most is 18, because it has 5 X's on the line plot. The answer is 18.

  6. Look at the pattern of circles arranged in rows: ○ ○ ○ ○ ○ ○ | ○ ○ ○ ○ ○ ○ | ○ ○ ○ ○ ○ ○ | ○ ○ ○ ○ ○ ○. There are 4 rows with 6 circles in each row. How many circles are there in total? Answer: 24 Solution: There are 4 rows of circles. Each row has 6 circles. To find the total number of circles, multiply the number of rows by the number of circles in each row: 4 × 6 4 × 6 = 24 The answer is 24.
    Full step-by-step solution

    Step 1: There are 4 rows of circles. Step 2: Each row has 6 circles. Step 3: To find the total number of circles, multiply the number of rows by the number of circles in each row: 4 × 6 Step 4: 4 × 6 = 24 The answer is 24.

  7. 48 + 25 = ? Answer: 73 Solution: Add the tens: 40 + 20 = 60. Add the ones: 8 + 5 = 13. Combine the results: 60 + 13 = 73.
    Full step-by-step solution

    Step 1: Add the tens: 40 + 20 = 60. Step 2: Add the ones: 8 + 5 = 13. Step 3: Combine the results: 60 + 13 = 73. The answer is 73.

  8. Make a line plot showing: 1, 3, 3, 5, 5, 5, 7, 7, 9, 11, 11, 13 Answer: The number 5 appears most often (3 times). Solution: List all the numbers: 1, 3, 3, 5, 5, 5, 7, 7, 9, 11, 11, 13.
    Full step-by-step solution

    Step 1: List all the numbers: 1, 3, 3, 5, 5, 5, 7, 7, 9, 11, 11, 13. Step 2: Count how many times each number appears: - 1 appears 1 time - 3 appears 2 times - 5 appears 3 times - 7 appears 2 times - 9 appears 1 time - 11 appears 2 times - 13 appears 1 time Step 3: The number that appears most often is 5, with 3 X's above it on the line plot. The answer is 5.
