Understand place value.
Where a digit is found in a number tells us how much it is
worth. 100 means there are ten bundles or groups of ten
objects. Understanding place value can lead to number sense
and efficient strategies for computing with numbers.

Understand place value.
The place of a digit in a number tells us how much it is worth.
100 means there are ten bundles or groups of ten objects.
Understanding place value can lead to number sense and
efficient strategies for computing with numbers. Numbers are
compared by the amounts of ones, tens and hundreds in each
number and use the <, >, = to show how they are different or
the same.
Represent and interpret data
The length of an object can be measured using standard tools
and units. Data can be organized and represented in many
ways. (i.e., bar graphs, line plots, pictographs, tally charts).
