Answer Key & Explanations

True/False Equations · Grade 1 · Worksheet 2

  1. True or false: 13 - 5 = 8 Answer: true Solution: Calculate the left side: 13 - 5 13 - 5 = 8 Compare to the right side: 8 Since 8 equals 8, the equation is true.
    Full step-by-step solution

    Step 1: Calculate the left side: 13 - 5 Step 2: 13 - 5 = 8 Step 3: Compare to the right side: 8 Step 4: Since 8 equals 8, the equation is true. The answer is true.

  2. Noah drew 11 squares in a row. Then he drew 6 more squares in another row. He says that 11 + 6 = 16. Is this true or false? Answer: false Solution: Noah has 11 squares in the first row. He adds 6 more squares in the second row. Count all the squares together.
    Full step-by-step solution

    Step 1: Noah has 11 squares in the first row. Step 2: He adds 6 more squares in the second row. Step 3: Count all the squares together. Start at 11 and count 6 more: 12, 13, 14, 15, 16, 17. Step 4: 11 + 6 = 17, not 16. Step 5: The equation 11 + 6 = 16 is false. The answer is false.

  3. Aroha has 9 toy cars. She gets 7 more toy cars for her birthday. Aroha says, '9 plus 7 equals 17.' Is this true or false? Answer: false Solution: Aroha starts with 9 toy cars. She gets 7 more, so we add: 9 + 7. Count on from 9: 10, 11, 12, 13, 14, 15, 16.
    Full step-by-step solution

    Step 1: Aroha starts with 9 toy cars. Step 2: She gets 7 more, so we add: 9 + 7. Step 3: Count on from 9: 10, 11, 12, 13, 14, 15, 16. Step 4: 9 + 7 = 16, not 17. Step 5: The statement says 9 + 7 = 17, which is incorrect. Therefore, the answer is false.

  4. True or false: 9 + 8 = 17 Answer: B. true Solution: Calculate the left side: 9 + 8 9 + 8 = 17 Compare to the right side: 17 Since both sides are equal (17 = 17), the equation is true.
    Full step-by-step solution

    Step 1: Calculate the left side: 9 + 8 Step 2: 9 + 8 = 17 Step 3: Compare to the right side: 17 Step 4: Since both sides are equal (17 = 17), the equation is true.

  5. A rectangle has 4 sides. Two sides are 8 units long and two sides are 5 units long. What is the total length of all the sides? Answer: 26 Solution: A rectangle has 4 sides. Identify the lengths of the sides. Two sides are 8 units long.
    Full step-by-step solution

    A rectangle has 4 sides. Step 1: Identify the lengths of the sides. Two sides are 8 units long. Two sides are 5 units long. Step 2: Add the lengths of all four sides. First, add the two sides that are 8 units long: 8 + 8 = 16 Step 3: Add the two sides that are 5 units long: 5 + 5 = 10 Step 4: Combine the totals from Step 2 and Step 3: 16 + 10 = 26 So, the total length of all the sides is 26 units.

  6. Liam has 8 stickers. His friend Emma gives him 5 more stickers. How many stickers does Liam have now? Answer: 13 Solution: Liam starts with 8 stickers. Emma gives him 5 more stickers. Add the stickers together: 8 + 5 8 + 5 = 13 Liam has 13 stickers now.

    Full step-by-step solution

    Step 1: A square has 4 sides. Step 2: All 4 sides are equal in length. Step 3: One side is 6 cm long. Step 4: To find the total distance around, add the length of all 4 sides: 6 + 6 + 6 + 6 Step 5: 6 + 6 = 12, and 12 + 6 = 18, and 18 + 6 = 24. The total distance around the square is 24 cm.
