Lesson Plan Session 3

Students will extend their place value understanding to the hundreds place by decomposing numbers into hundreds, tens, and ones, then using hands-on mats to solve addition and subtraction word problems.

Building on tens work, introducing hundreds deepens number sense and prepares students for multi-digit computation and real-world problem solving.
