Exemplars (from the NaCCA curriculum)

E.g. 1. Demonstrate a conceptual understanding of place value of whole numbers between 100 and 10,000 by:
- explaining and showing - with bundles of hundreds, tens and ones - the meaning of each digit in a given 3-digit number (when the three digits are different, as well as when two or more of the digits are the same) and representing the number in a hundreds frame
- explaining why the value of a digit depends upon its placement within a numeral.
- using other possible representations of place value which include manipulatives such as threaded 100s, 10s, and loose bottle caps; and multi-base ten material (units, flats and squares)
E.g.2 Ask pupils to model number quantities up to 10,000 using square grid paper or multi-base materials. For instance, with multi-base block, a cube = 1 unit; a rod = 10; a flat = 100 and a block = 1000; learners model 327 with the appropriate materials.

E.g. 3. Decompose numbers up to 1000 into 100s, 10s, and 1s expressions (e.g.: 5000 = 1000 + 1000 + 1000 + 1000 + 1000 or 4036 = 4000 + 30 + 6; etc.)

E.g. 4. Explain why the value of a digit depends upon its placement within a numeral.
E.g. 5. Read a given number up to 1000 by indicating the value of each digit (i.e., reading 435 as four hundred and thirty-five and not four three five. The "Hundreds frame" table is set beside E.g. 3 to E.g. 5 and its words interleave with theirs in the text layer. Its column headings read Ten Thousands, Thousands, Hundreds, Tens, Ones and its cells are blank; figure p44-2.png shows it.
