Comparing lengths

Google Classroom
Measure and find difference between lengths.

Comparing lengths by measuring

We can compare lengths by measuring each length and comparing their measures.

First, let's measure.

Use the ruler to measure the length of each side of the triangle.
What is the length of Side A?
  • Your answer should be
  • an integer, like 6
units

What is the length of Side B?
  • Your answer should be
  • an integer, like 6
units

What is the length of Side C?
  • Your answer should be
  • an integer, like 6
units

Now, let's compare.

Side A is
  • Your answer should be
  • an integer, like 6
  • a simplified proper fraction, like 3/5
  • a simplified improper fraction, like 7/4
  • a mixed number, like 1 3/4
  • an exact decimal, like 0.75
  • a multiple of pi, like 12 pi or 2/3 pi
units shorter than Side C.

Side B is
  • Your answer should be
  • an integer, like 6
  • a simplified proper fraction, like 3/5
  • a simplified improper fraction, like 7/4
  • a mixed number, like 1 3/4
  • an exact decimal, like 0.75
  • a multiple of pi, like 12 pi or 2/3 pi
units longer than Side A.

What is the length of Side B and Side C together?
  • Your answer should be
  • an integer, like 6
  • a simplified proper fraction, like 3/5
  • a simplified improper fraction, like 7/4
  • a mixed number, like 1 3/4
  • an exact decimal, like 0.75
  • a multiple of pi, like 12 pi or 2/3 pi
units
