Counter of Quantitative Units/Place Value


Understands the base-ten numeration system and place value concepts, including ideas of counting in units and multiples of at least tens and ones. When counting groups of 10, can decompose into 10 ones if that is useful. Understands the value of a digit according to the place of the digit within a number. Counts unusual units, such as “wholes” when shown combinations of wholes and parts.

Other Examples:

  • When given sticks with bundles of 10 and some singles, a child counts by tens and then ones to determine the total number of sticks.
  • When shown 3 whole plastic eggs and 4 halves, a child counts and says there are 5 whole eggs.

Help your student become a(n) Counter of Quantitative Units/Place Value

These activities help children learn to count in different units, switching during the same count. The scaffolding includes using bundled manipulatives or dollar bills in different denominations as well as math talk. Another way of counting different units is counting fractional units (e.g., two halves of an egg) as one whole.
