About the Mathematics in This Unit

Dear Family,

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.

Throughout this unit, students will be working toward these goals:

Benchmarks	Examples
Solve a 2-step story problem that involves finding the difference between a 2-digit number and 100.	Franco has 35¢. Sally has 37¢. How much money do they need to buy a comic book that costs $1.00?
Understand that 3-digit numbers represent amounts of hundreds, tens, and ones.	“There are two sheets of 100, 3 strips of 10, and 4 singles. There are two hundreds, 3 tens, and 4 ones. 234 = 200 + 30 + 4.”
Read, write, count, and compare numbers to 1,000.	d
