Mathematical Standards

1.MD.1
Measure lengths indirectly and by iterating length units. (1.MD.A.1)
1.NBT.B
Understand place value. (1.NBT.B.3)

Standards for Mathematical Practice

MP2.
Reason quantitatively.
MP5.
Use appropriate tools strategically.

Students continue to compare quantities, such as length and area, and are introduced to the symbols representing “greater than,” “less than,” and “equal to.”

Content in this Lesson

  • Comparing and ordering quantities (e.g., lengths and areas) [E1].
  • Using symbols to represent “greater than,” “less than,” or “equal to” [E2].
