Description

This Second Grade 2-Digit Addition & Subtraction Math Unit is designed to be teacher and student-friendly with math lessons and activities that are fun, engaging, and easy to prep. Whether you are looking for a stand-alone curriculum or a supplement to your required school curriculum, this comprehensive unit has everything you need to teach second grade standards with ease.

Not all math curriculum is awful. Just sum. Ba-da-bum!

But when it is bad, it is very, very bad. And unfortunately, a lot of traditional math curriculum is very, very bad. It’s overly complex, too long, impossible to differentiate, difficult to manage, and, frankly, not much fun. It can be hard to wade through all the extras and find the most valuable parts of the lesson. You don’t have time to read dozens of pages in the teacher manual and there are way too many different pieces to prep. Ugh!

If that sounds like your math curriculum, you’re in luck. Because now you have an alternative that is very, very good. A math curriculum that you and your students will LOVE!
