It will show you the table of contents to give you an idea of what is included! :) In the actual unit, you can click on those links to quickly go to that activity in the unit. This unit is structured like my other math units - 3 levels of differentiated worksheets, math centers, and cut and pastes for each concept (4.1 on the cover is 1 concept, for example) and also 3 assessments at the end of the unit. I have TONS of pictures of some of my other math units on my blog if you want to peek inside my math units! I don't have a blog post for this specific unit, but I do for these:

Building Number Sense (Unit 1)

Graphing and Data Analysis (Unit 16)

Adding 3 Numbers (Unit 12)

Fact Fluency in First Grade (Fact fluency portion of Unit 10)

Place Value (Unit 9)

Money (shows U.S. money unit but I also have U.K., Australian, and Canadian coins versions of everything I show in their respective money units)

** ADDED 10-24-2021: I added a black and white version of the popular "Is My Bubble A Double?" math center so you can make it into a cute craft like my Fraction Flowers from Unit 18! :) You could also simply have kids color the pieces and use it as a sort OR print it on color paper to make it super colorful while saving on color ink than if you were to print the center in color. I hope you love it! If you already own this, simply redownload to grab it!

This is everything you need to print and go to teach these concepts to a variety of learners - it will save you so much time! Plus, ALL of your students will be learning and having fun at their own level since everything is already differentiated for you! This pack will make your math planning a breeze!

Each of the concepts come with differentiated worksheets in 3 levels as well as engaging math stations for your students to practice the skill. The math stations come with teacher directions to help you use them as effectively as possible as well as student friendly guided directions so that the centers can be completely independent if you choose!
