Better Lesson: Using Models to Add and Subtract
Common Core standards encourage the use of models to build understanding in math. This lesson shows sometimes reluctant 2nd graders that models are helpful tools in solving mathematical problems.
Better Lesson
Better Lesson: Time and Money
As the result of a Unit assessment, it was found that students showed some confusion with writing time and with adding sets of coins. These skills need to be reviewed to aid in mastery of the Common Core standards for time and money.
Better Lesson
Better Lesson: Balancing and Comparing Data
The connection between subjects is an important one to establish for students. Communicating across subjects is part of the Common Core expectations.

Better Lesson: Our Understanding of Numbers
This lesson is an informal assessment of student understanding of the base ten system, a critical area in the Common Core.
Better Lesson
Better Lesson: We Can Guess the Number
Understanding place value is critical to the Common Core Standards for second grade. Without a concrete understanding, 2nd graders may not fully grasp the meaning of the digits.
Better Lesson
Better Lesson: Moving Along in Hundreds
The Common Core standard is that students understand that the numbers 100, 200, etc. represent so many groups of 100.
