Content in this Lesson

  • Representing numbers to the thousandths using fractions, decimals, words, and number lines [E1].
  • Making connections among representations of decimals including fractions, words, number lines, and number sentences [E2].
  • Recognizing that in a multidigit number, a digit in one place represents 10 times as much as it represents in the place to its right and 1/10 of what it represents in the place to its left [E5].
  • Explaining the patterns in the number of zeros of the product when multiplying by a number by powers of 10, and explaining patterns in the placement of the decimal point when a decimal is multiplied or divided by a power of ten [E6].

Materials for the Teacher

Materials Preparation

Choose Distance to Measure. Each pair of students will need a distance to measure. They will measure the same distance in meters, centimeters, and millimeters. Describe or identify each distance on a sheet of paper that will be distributed to each student pair. Some example distances: height of doorknob, length of desk, width of desk, length of table, height of bookcase, width of rug, length of rug.
