Mathematical Standards

4.MD.A
Solve problems involving measurement and conversion of measurements. (4.MD.A.1, 4.MD.A.2)
4.OA.B
Gain familiarity with factors and multiples. (4.OA.B.4)
4.OA.C
Generalize and analyze patterns. (4.OA.C.5)

Standards for Mathematical Practice

MP1.
Make sense of problems and persevere in solving them.
MP2.
Reason quantitatively.
MP3.
Construct viable arguments and critique the reasoning of others.
MP4.
Model with mathematics.
MP7.
Look for and make use of structure.
MP8.
Look for and express regularity in repeated reasoning.

Students identify relationships between units of measure (e.g., liters and milliliters) by looking for patterns in function tables and writing rules to express the relationships.

Content in this Lesson

  • Identifying and extending patterns for increasing functions [E1].
  • Making generalizations using data tables [E12].
  • Generating a pattern from a rule [E3].
  • Representing patterns and functions using words, symbols, and tables [E2].
  • Using the relationship between larger and smaller units of measure to solve problems [E5].
