              Essential Questions                            Knowledge & Skills
   What is a decimal?                            Students will be able to compare and
   How can we model decimals to be                contrast decimals and will work to solve
    equivalent to each other?                      problems. 4.1.A, B
   Is the decimal equivalent to the base ten     Students will use a number line to
    blocks represented?                            represent and understand relationships
   How many different ways can we                 between decimals. 4.5.E
    represent a decimal with base ten blocks?
   Are decimals measurable?
   Can we use number lines to represent
    decimals in least to greatest format?

                                 Assessment Evidence
   Students will be able to explain the meaning of a decimal.
   Students will be able to measure each decimal and represent its value using base ten blocks.
   Students will be able to order and compare decimals.

 Allow students to work in groups with base ten blocks to review ones, tenths and
  hundredths.
 Complete equivalency worksheet using base ten blocks to represent decimals
 Review problems on worksheets given and record responses using base ten value system.
  (Grid paper may also be used)
 Review ordering decimals from least to greatest during guided practice.
 Have students record their responses by creating a number line on a sentence strip. (Register
  tape optional)
 Discuss solutions recorded and have students share their representations of the problem.
