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 start color #11accd, start text, S, i, d, e, space, A, end text, end color #11accd?
  • Your answer should be
  • an integer, like 6
units

What is the length of start color #1fab54, start text, S, i, d, e, space, B, end text, end color #1fab54?
  • Your answer should be
  • an integer, like 6
units

What is the length of start color #aa87ff, start text, S, i, d, e, space, C, end text, end color #aa87ff?
  • Your answer should be
  • an integer, like 6
units

Now, let's compare.

start color #11accd, start text, S, i, d, e, space, A, end text, end color #11accd is
  • Your answer should be
  • an integer, like 6
  • a simplified proper fraction, like 3, slash, 5
  • a simplified improper fraction, like 7, slash, 4
  • a mixed number, like 1, space, 3, slash, 4
  • an exact decimal, like 0, point, 75
  • a multiple of pi, like 12, space, start text, p, i, end text or 2, slash, 3, space, start text, p, i, end text
units shorter than start color #aa87ff, start text, S, i, d, e, space, C, end text, end color #aa87ff.

start color #1fab54, start text, S, i, d, e, space, B, end text, end color #1fab54 is
  • Your answer should be
  • an integer, like 6
  • a simplified proper fraction, like 3, slash, 5
  • a simplified improper fraction, like 7, slash, 4
  • a mixed number, like 1, space, 3, slash, 4
  • an exact decimal, like 0, point, 75
  • a multiple of pi, like 12, space, start text, p, i, end text or 2, slash, 3, space, start text, p, i, end text
units longer than start color #11accd, start text, S, i, d, e, space, A, end text, end color #11accd.

What is the length of start color #1fab54, start text, S, i, d, e, space, B, end text, end color #1fab54 and start color #aa87ff, start text, S, i, d, e, space, C, end text, end color #aa87ff together?
  • Your answer should be
  • an integer, like 6
  • a simplified proper fraction, like 3, slash, 5
  • a simplified improper fraction, like 7, slash, 4
  • a mixed number, like 1, space, 3, slash, 4
  • an exact decimal, like 0, point, 75
  • a multiple of pi, like 12, space, start text, p, i, end text or 2, slash, 3, space, start text, p, i, end text
units
