Let’s go through each item one by one and think about which tool is best for measuring it.
We have three tools to choose from:
-
Ruler – good for straight, short lengths (like a pencil or book)
-
Tape Measure – flexible, good for curves or longer distances (like around your waist or the height of a door)
-
Scale – used to measure weight (how heavy something is)
Now let’s match each object:
1.
The height of a door → This is tall and straight, but too long for a ruler. A tape measure can reach up high and bend if needed.
→
Tape Measure
2.
A baby’s weight → Weight means how heavy something is. We use a scale for that.
→
Scale
3.
Around your waist → This is curved and goes around your body. Only a flexible tape measure can do this.
→

4.
The weight of vegetables → Again, “weight” = use a scale.
→

5.
The length of pants → Pants are long and you might need to measure along the leg or waistband. Tape measure works best.

6.
How long a pencil is → Pencil is short and straight. Perfect for a ruler.
→

7.
How much a person weighs → Weight again → Scale.
→

8.
The length of a sub sandwich → It’s straight and not too long — ruler should work fine.
→
Ruler
9.
The distance around a ball → That’s the circumference — it’s curved! You need a flexible tape measure to wrap around it.
→

10.
The length of a book → Book is flat and straight, usually under 12 inches. Ruler is perfect.
→
Ruler
All answers checked and make sense based on what each tool does.
