First-grade worksheet for measuring objects using units.

Let's solve this step-by-step based on the image you've described. This is a first-grade measurement worksheet where students are asked to measure objects by counting how many units long they are, using a grid of squares as a reference.

Each object is drawn above a row of blank squares (units), and the goal is to determine how many of these squares the object covers when aligned properly.

Step 1: Understand the Task

- Each square represents 1 unit.
- We need to count how many squares each object spans from one end to the other.
- The object must be aligned with the beginning of the grid, and we count only the squares it covers completely or partially (typically in such worksheets, partial units are not counted unless specified — but here, all objects appear to align perfectly).

Step 2: Measure Each Object

#### 1. The Pen
- Look at the pen drawing.
- It starts at the left edge of the first square and extends to the right.
- Count the number of squares it covers:
- From the tip to the end, it fills 10 squares.
✔ The pen is 10 units long.

---

#### 2. The Rod
- The rod is thinner and has a slight curve at the end.
- It starts at the first square and ends just before the last square.
- Count the squares it covers:
- It fills 8 squares.
✔ The rod is 8 units long.

---

#### 3. The Spoon
- The spoon has a large bowl and a handle.
- The bowl is wide, but we measure along the length of the spoon’s handle and bowl.
- It starts at the first square and ends after covering 9 squares.
✔ The spoon is 9 units long.

---

#### 4. The Tube
- The tube looks like a marker or crayon.
- It is thick and straight.
- It starts at the first square and goes through 11 squares.
✔ The tube is 11 units long.

---

✔ Final Answers:

- The pen is 10 units long.
- The rod is 8 units long.
- The spoon is 9 units long.
- The tube is 11 units long.

📝 Explanation for Students:

You can measure an object by placing it next to a ruler made of squares. Then, count how many squares the object touches from start to finish. That number tells you how long it is in "units."

This activity helps build foundational skills in measurement and number sense, aligned with Common Core Standard 1.MD.2.
