Grade: 4 Lesson Title: Measurement Conversion

Unit: 2 (Lesson 6 of 6)Time Frame:4-5 days

Essential Question: Why does the size, length, mass, volume of an object remain the same when converted to another unit of measurement?

Targeted Content Standard(s): / Student Friendly Learning Targets
4.MD.1 Know relative sizes of measurement units within one system of units including km, m, cm; kg, g; lb., oz.; l. ml; hr, min, sec. Within a single system of measurement, express measurements in a larger unit in terms of a smaller unit. Record measurement equivalents in a two-column table. For example, know that if 1 ft is 12 times as long as 1 in. Express the length of a 4 ft snake as 48 in. Generate conversion table for feet and inches listing the number pairs (1, 12), (2,24), (3, 36), …
4.MD.2 Use the four operations to solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money, including problems involving simple fractions / I can…
  • Name the relative size of measurements within a set of units, e.g. 1 feet = 12 inches.
  • Record measurements in a two-column table.
  • Find the pattern in a table to see how many times larger one unit is compared to the other.
  • State the length of an object in related units (2 ft. = 24 in.)
  • Convert between units to solve “real world” measurement problems.

Targeted Mathematical Practice(s):

3Construct viable arguments and critique the reasoning of others
4Model with mathematics
5Use appropriate tools strategically
6Attend to precision
7 Look for and make use of structure
8 Look for an express regularity in repeated reasoning
