Number and Operations in Base Ten
Work with numbers 11-19 to gain foundations for place value.
Composed of ten ones and more ones.
Decomposed into ten ones and more ones.
Use place value understanding to round whole numbers to the nearest 10 or 100.
Compose and decompose numbers from 11 to 19 into ten ones and some further ones, e.g., by using objects or drawings, and record each composition or decomposition by a drawing or equation (e.g., 18 = 10 + 8); understand that these numbers are composed of ten ones and one, two, three, four, five, six, seven, eight, or nine ones.
10 can be thought of as a bundle of ten ones-called a “ten”.
Recognize that in a multi-digit whole number, a digit in one place represents ten times what it represents in the place to its right.
Understand that the three digits of a three-digit number represent amounts of hundreds, tens, and ones; and demonstrate that:
The numbers 10, 20, 30, 40, 50, 60, 70, 80, 90 refer to one, two, three, four, five, six, seven, eight, or nine tens (and 0 ones).
The numbers from 11 to 19 are composed of a ten and one, two, three, four, five, six, seven, eight, or nine ones.
