Objective: Students use 100’s chart to predict next numeral in line.

Materials: 100’s chart, chart paper

Manipulative Activity:

  1. Post 100’s chart
  2. Attach chart paper below the first row of numbers
  3. Explain to the children or have them describe how or what each row of numerals have in common
  4. They will note that each column of numbers has the same number as the top number

  8. Students will be able to see a number pattern. Each two digit number in the row has the same number on the right.
  9. Use chart paper to display one row at a time

Technology Activity: Students will use the applet, Attribute Blocks, from the National Library of Virtual Mathematics Manipulatives. Depending on the availability of computers for your students, this activity could be done individually, with partners, in groups, or as a class.

Have students go to What Comes Next?
