Students make connections between different representations of numbers through one thousand. They apply their knowledge of place value concepts to represent and compare multidigit numbers.

Content in this Lesson

  • Using and applying place value concepts to make connections among representations of multidigit numbers using base-ten pieces, number lines, expanded form, and standard form [E1].
  • Composing and decomposing numbers using ones, tens, hundreds, and thousands [E2].
  • Showing and recognizing different partitions of multidigit numbers using different representations (e.g., base-ten pieces, number lines, number sentences) [E3].
  • Comparing and ordering multidigit numbers using base-ten pieces, number lines, and symbols (e.g., <, >, =) [E4].

One Hundred Hungry Ants by Elinor J. Pinczes
10 sheets of card stock or heavy paper. See Materials Preparation.
1 prepared slip of paper for each student. See Materials Preparation.
Display set of base-ten pieces (2 packs, 11 flats, 20 skinnies, 21 bits)
glue or tape
construction paper for class book, optional

Materials Preparation

Triangle Flash Cards. Prepare copies of the Triangle Flash Cards on heavier paper or card stock. Have students cut apart each set and store them in an envelope. Provide each student with two sets, one to use at school and one to take home. Students will need these cards on an ongoing basis.

Prepare Display of 1000 Ants. Make ten copies of the 100 Ants Master on cardstock or heavy paper. Arrange the pages horizontally and glue or tape the pages together to make an accordion fold book. See Figure 1.

Prepare Number Slips for Bubble Sort. Prepare one slip of paper for each student in your classroom. Write a number from 100 to 1000 on each slip of paper. The majority of numbers should be from 100 to 1000 but include some numbers from 1–100. Students will compare and order the numbers during a Bubble Sort.
