Standards for Mathematical Practice

MP2.
Reason quantitatively.
MP3.
Construct viable arguments and critique the reasoning of others.
MP4.
Model with mathematics.

Students explore the relative size among numbers. Using two-digit numbers in news headlines, students describe the relationship of one number to others.

Content in this Lesson

  • Representing and identifying numbers to 100 using number lines, 100 Chart, and symbols [E1].
  • Comparing quantities and representing that relationship using less than, greater than, between, and closer to [E3].
  • Analyzing the reasoning of others.

Materials Preparation

Prepare Newspaper Headlines on Construction Paper. You will need one headline containing two-digit numbers for each pair of students. Find and cut out several headlines from articles in periodicals. If you prefer, cut out the headlines from 1–2 copies of the Numbers in the News Master. Attach one headline to the top of a 12" × 18" piece of construction paper.

Prepare Headline on Chart. Write the headline "34 Kids Think in Math Marathon" at the top of a piece of chart paper. See Figure 1.

Prepare Comparative Statements on Chart. On a second piece of chart paper, write a two-digit number that has not yet been explored (e.g., 57). Write comparative statements about this number. Include some statements that are true and some that are false. See examples about the number 57.

My Number is 57.

  • This number is about the same size as 60.
  • This number is between 50 and 60.
  • This number is 7 more than 50.
  • This number is 3 less than 60.
  • This number is a lot less than 100.
  • This number is large compared to 3.
  • This number is 10 more than 47.
  • This number is > 50.
