:"Understand that the two digits of a two-digit number represent amounts of tens and ones. Understand the following as special cases:"
Our Take: Students are taught that a two-digit number is composed of tens and ones. This reflects a shift in their thinking from viewing numbers as single units ("ones") to a bundle of units. Specifically, the first grader should learn that a bundle of ten "ones" equals one “ten.” They can use this knowledge to figure out, for example, that four “tens” is 40.
These worksheets, games, lesson plans, and teacher editions can help students practice this Common Core State Standards skill.
