2nd Grade

About the Mathematics in Unit 5

We are beginning a new unit in mathematics called How Many Tens? How Many Hundreds? In this third number unit of Grade 2, students continue to work on solving addition and subtraction problems, understanding place value and the composition of 3-digit numbers, and adding and subtracting 2-digit numbers. They also continue to practice addition and subtraction facts to 20 with the goal of becoming fluent with these facts by the end of Grade 2.
