    Step 1: Look at the sequence: 615, 620, __, 630 Step 2: The pattern is skip counting by 5s (adding 5 each time) Step 3: 615 + 5 = 620 Step 4: 620 + 5 = 625 Step 5: 625 + 5 = 630 Step 6: The missing number is 625 The answer is 625.

  3. Skip count by 10s: 482, 492, __, 512 Answer: 502 Solution: Look at the sequence: 482, 492, __, 512 The pattern is skip counting by 10s (adding 10 each time) 482 + 10 = 492 492 + 10 = 502 502 + 10 = 512 The missing number is 502 The answer is 502.
    Full step-by-step solution

    Step 1: Look at the sequence: 482, 492, __, 512 Step 2: The pattern is skip counting by 10s (adding 10 each time) Step 3: 482 + 10 = 492 Step 4: 492 + 10 = 502 Step 5: 502 + 10 = 512 Step 6: The missing number is 502 The answer is 502.

  4. Charlotte is counting her collection of colored pencils. She has 127 pencils. Her friend Isabella gives her 2 more pencils. How many pencils does Charlotte have now? Answer: 129 Solution: Start with the number of pencils Charlotte has: 127. She gets 2 more pencils, so we count forward by 2. Count forward 1: 127 → 128.
    Full step-by-step solution

    Step 1: Start with the number of pencils Charlotte has: 127. Step 2: She gets 2 more pencils, so we count forward by 2. Step 3: Count forward 1: 127 → 128. Step 4: Count forward another 1: 128 → 129. Step 5: So, 127 + 2 = 129. The answer is 129.

  5. Olivia is practicing skip counting by 5s. She says, 215, 220, 225, __, 235. What number is missing from Olivia's counting? Answer: 230 Solution: Olivia is skip counting by 5s. This means she adds 5 to each number to get the next number. The last number she said was 225.
    Full step-by-step solution

    Step 1: Olivia is skip counting by 5s. This means she adds 5 to each number to get the next number. Step 2: The last number she said was 225. Step 3: Add 5 to 225: 225 + 5 = 230. Step 4: Check: 215, 220, 225, 230, 235. The pattern works. The answer is 230.

  6. A rectangular garden is divided into 4 equal rows. Each row has 6 flowers. How many flowers are in the garden in total? Answer: 24 Solution: The garden is divided into 4 equal rows. Each row has 6 flowers. We need to find the total number of flowers.
    Full step-by-step solution

    Step 1: Understand the problem. The garden is divided into 4 equal rows. Each row has 6 flowers. We need to find the total number of flowers. Step 2: Determine the operation to use. Since there are 4 rows and each row has the same number of flowers (6), we can multiply the number of rows by the number of flowers per row. Step 3: Perform the multiplication. Number of rows = 4 Flowers per row = 6 Total flowers = 4 × 6 Step 4: Calculate. 4 × 6 = 24 Step 5: State the final answer. There are 24 flowers in the garden in total.

  7. A farmer plants apple trees in rows. There are 8 rows with 6 trees in each row. How many apple trees are there in total? Answer: 48 Solution: The farmer has 8 rows of apple trees.

    Full step-by-step solution

    Step 1: Understand the problem. The farmer has 8 rows of apple trees. Each row has 6 trees. To find the total number of trees, we need to multiply the number of rows by the number of trees in each row. Step 2: Write the multiplication expression. Number of rows = 8 Number of trees per row = 6 Total trees = 8 × 6 Step 3: Perform the multiplication. 8 × 6 = 48 Step 4: State the final answer. There are 48 apple trees in total.
