Students read, write, and represent a given number of objects numerically and extend the counting sequence to 120. They demonstrate the ability to count from any number up to 120 and count backward from 20. Students understand that two-digit numbers represent groups of tens and ones and each two-digit number can be composed and decomposed in a variety of ways. Using place value understanding, students compare two-digit numbers based on the number of tens and ones represented in the given numbers using symbols for comparison. Students build number sense and use increasingly sophisticated strategies based on place value and properties of operations to add and subtract.
