Diffy Inception: Whole Numbers (PDF)

The ebooks are written to be read. They include more inspiration, background information, and teaching tips, but do NOT include printable student pages.

You can think of the ebooks as a "teacher's manual" for their related printable activities.

The printable activity guides include brief teacher instructions, but the focus is on the student handout pages, making the activities easy to use in a classroom or homeschool. Many of the printable guides also include math journaling prompts and decorated pages for student writing.

Ebooks come in two formats: DRM-free EPUB file (for reading on your phone or ebook reader) and a PDF (for reading on a tablet). The activity guides come in printable PDF format only.

Either type can stand alone, though we believe they work better together. If you're on a tight budget, the ebook is often the better deal.

Printable files are delivered by email with your download links.

You can read your printable activity guide in any browser or PDF app. Print as many copies as you need for use in your own classroom, homeschool, or local co-op class.

Ebooks and printable activities are delivered immediately by electronic file download. They cannot be returned.

The only exception is for duplicate orders. If you accidentally purchase the same item twice, contact us immediately to get the second order refunded.
