Measuring Objects Worksheets for Grade 1

Learn to measure length, height, and compare objects using non-standard units with fun exercises and activities.

Measurement Exercises 1-3
1 Comparing Lengths
Exercise 1
Which pencil is longer? Use the paper clips to measure each pencil.
Pencil A: 📏📏📏📏 (4 paper clips)
Pencil B: 📏📏📏 (3 paper clips)
Circle the longer pencil.
Definition:

Length: How long something is from one end to the other.

Non-standard unit: Using objects like paper clips, blocks, or cubes to measure.

Measurement method:
  1. Line up the measuring units end-to-end along the object
  2. Count the number of units used
  3. Compare the numbers to find the longer object
Step 1: Measure Pencil A

Pencil A = 4 paper clips long

Step 2: Measure Pencil B

Pencil B = 3 paper clips long

Step 3: Compare the measurements

4 paper clips > 3 paper clips, so Pencil A is longer

Applied rules:

• Consistent units: Use the same size measuring units

• End-to-end: Place units touching each other without gaps

• Comparison: Larger number means longer object

Final answer:

Pencil A is longer because it measures 4 paper clips compared to Pencil B's 3 paper clips.

Tip: Always start measuring from the beginning of the object.
Tip: Count carefully and double-check your count.
2 Height Comparison
Exercise 2
Measure the height of each tower using cubes.
Tower A: 🧱🧱🧱 (3 cubes tall)
Tower B: 🧱🧱🧱🧱 (4 cubes tall)
Tower C: 🧱🧱 (2 cubes tall)
Which tower is the tallest? Which is the shortest?
Definition:

Height: How tall something is from bottom to top.

Tallest: The highest or longest in height.

Shortest: The lowest or smallest in height.

Height measurement method:
  1. Stack measuring units vertically from bottom to top
  2. Count the number of units stacked
  3. Compare heights to determine tallest/shortest
Step 1: Measure Tower A

Tower A = 3 cubes tall

Step 2: Measure Tower B

Tower B = 4 cubes tall

Step 3: Measure Tower C

Tower C = 2 cubes tall

Step 4: Compare heights

4 cubes > 3 cubes > 2 cubes

Applied rules:

• Vertical measurement: Stack units from bottom to top

• Comparison: Higher number = taller object

• Ordering: Arrange from tallest to shortest or vice versa

Final answer:

Tower B is the tallest (4 cubes), Tower C is the shortest (2 cubes).

Tip: Stack cubes straight and aligned to get accurate measurements.
Tip: Write down measurements to keep track of comparisons.
3 Weight Comparison
Exercise 3
Look at the balance scale:
Left side: Apple 🍎
Right side: 3 blocks 🧱🧱🧱
The scale is balanced. How many blocks does the apple weigh?
If another apple weighs 4 blocks, which apple is heavier?
Definition:

Weight: How heavy something is.

Balanced: Both sides of the scale are equal in weight.

Heavier: Weighs more than another object.

Weight comparison method:
  1. Place object on one side of the balance scale
  2. Add standard units (blocks) to the other side
  3. Count units when scale balances
  4. Compare weights of different objects
Step 1: Analyze the balanced scale

Apple = 3 blocks (scale is balanced)

Step 2: Compare with second apple

First apple = 3 blocks, Second apple = 4 blocks

Step 3: Determine which is heavier

4 blocks > 3 blocks, so the second apple is heavier

Applied rules:

• Balance principle: Equal weights make the scale level

• Comparison: More units = heavier object

• Standard units: Use consistent measuring objects

Final answer:

The first apple weighs 3 blocks. The second apple (4 blocks) is heavier than the first.

Tip: A balanced scale means both sides weigh the same amount.
Tip: The side that goes down has the heavier object.
Measurement Concepts & Units
Length = Number of Units × Unit Size
Basic Measurement Formula
Length Measurement
📏 → 📏📏
How long? From end to end
Height Measurement
🡇 → 🡅
How tall? From bottom to top
Weight Comparison
⚖️ ↔ ⚖️
How heavy? Balance scale
Non-standard units: Paper clips, cubes, blocks, hands, feet
Comparison symbols: > (greater than), < (less than), = (equal to)
Ordering: Tallest → Shortest, Longest → Shortest
Key Tip: Always use the same size units for accurate comparison.
Key Tip: Start measuring from the beginning of the object.
Key Tip: Count carefully and check your work.
Measurement Rules, Laws, and Q&A
Key definitions:

Measurement: Finding out how big, long, tall, or heavy something is.

Unit: What we use to measure (paper clips, cubes, etc.).

Compare: Looking at two things to see which is bigger, smaller, taller, shorter, heavier, or lighter.

Measurement methodology:
  1. Choose units: Select appropriate non-standard units (same size)
  2. Measure: Line up units end-to-end or stack them
  3. Count: Count the total number of units used
  4. Compare: Use numbers to compare different objects
Essential rules:

• Consistency: Use units of the same size for fair comparison

• Accuracy: Place units without gaps or overlaps

• Starting point: Begin measuring from the edge of the object

• Counting: Count each unit carefully

Measurement Q&A

Question: Why do we need to use the same size units when measuring different objects?

Answer: Great question! Using the same size units is like having a fair race. If you measure one pencil with small paper clips and another with large paper clips, you can't really compare them fairly. Think of it this way:

  • If Object A = 3 small units and Object B = 2 large units, we don't know which is actually longer
  • But if both are measured with the same size units, we can make accurate comparisons
  • This is called having "consistent units" - it makes our measurements reliable

Example: If you measure your desk with your hand and your friend measures the same desk with their foot, you'll get different numbers even though it's the same desk!

Question: My child gets confused between length, height, and width. How can I help them understand the differences?

Answer: This is very common for young learners! Here's how to make the concepts clear:

  • Length: "How long?" - Measure from one end to the other (left to right)
  • Height: "How tall?" - Measure from bottom to top (up and down)
  • Width: "How wide?" - Measure from side to side (front to back)

Practical examples to try:

  • Book: Length = spine to cover, Height = bottom to top of pages, Width = thickness
  • Table: Length = longest side, Width = shorter side, Height = from floor to top
  • Box: Use different colored units for each dimension

Use hand gestures - horizontal for length, vertical for height, and side-to-side for width!

Question: Sometimes when I measure, my units don't fit perfectly. Should I still count them?

Answer: Yes, but be careful! When measuring with non-standard units, sometimes the last piece doesn't fit perfectly. Here's what to do:

  • If most of the unit fits (more than half), count it as a full unit
  • If only a little bit fits (less than half), don't count it
  • Try to place units neatly without gaps or overlaps

For example: If you're measuring a pencil with paper clips and the 4th clip only covers half the remaining space, you might say "about 3.5 paper clips" or just "about 4 paper clips" depending on your teacher's instructions.

The important thing is to be consistent with how you handle partial units across all your measurements!
