Integer Composition
Use place-value understandings to round whole numbers to the nearest 10.

Vocabulary:

ones, tens, equal, round up, round down

Activities:

  • Students were given 2 digit numbers and asked whether to round up or down
  • After identifying which is in ones, and tens place, students were given popsicle sticks numbered from 1-50 to place it in the cup that is labeled (0,10,20,30,40,50).

Home Exploration

Identify to round down or up to the nearest 10 the following numbers:

  1. 34 (30 or 40?)
  2. 22 (20 or 30?)
  3. 46 (40 or 50?)
  4. 21 (20 or 30?)
  5. 29 (20 or 30?)

Four-years-olds were little, so 4's got rounded down. And that 5-years-olds really want to be big so 5's and above get rounded up.

In other words, 0,1,2,3,4 round down/goes to the number to the left. And then 5,6,7,8,9 round up/goes to the number to the right.
