Number and Operations in Base Ten
Work with numbers 11-19 to
gain foundations for place value.
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.
