All other questions:

Please read below to see answers to our most frequently asked questions.

  • Registration

  • If I have an i-Ready account, do I still need to register?

    Yes, the Toolbox and i-Ready are separate products, so your i-Ready credentials will not work for the Toolbox.  If you are not sure whether you should have access to the Toolbox along with i-Ready, check with your administrator to find out whether your school purchased access to the Toolbox.

  • License Codes

  • How do I receive my codes?

    Check with your administrator to find out how your school purchased the Toolbox. If you are using the Toolbox in conjunction with the Ready print product, you should have been shipped Teacher Toolbox Access Packs, each with a unique code. If you bought the Toolbox to use with i-Ready, you should have received an e-mail with information on how to access the content.

  • My code is not working. What should I do?

    First, please make sure you have registered for the Toolbox and are logged in with your email address and password before you try to enter your code. As you enter your code, please make sure it appears the same as it does on your license code package (e.g., a zero has not been entered as an O). Also remember license codes are unique. Therefore, if someone has already redeemed that code, you may contact your administrator to see if they have additional codes or toolboxsupport@cainc.com for more information.

  • Frequently Asked Questions about Content

  • Why can't I access all the subjects?

    Reading, Writing and Math licenses are sold separately, so please be sure that your school or district has ordered the subjects you are looking for. If you aren’t able to access an additional subject, please contact Customer Service at 800-225-0248 or toolboxsupport@cainc.com.

  • Can I post PDF’s from the Toolbox to my District’s Learning Management System (LMS), on my school or class web site, or post to a Google classroom?

    No, you cannot post or upload any content from the Ready Teacher Toolbox. This includes posting or uploading to a LMS or Google classroom, or posting the PDFs on a school or class web site. The Ready Teacher Toolbox includes materials from third parties; Curriculum Associates’ agreements with these third parties do not permit posting or uploading of PDFs in this manner.

  • Can I print out and make copies of PDFs from the Toolbox?

    The PDF files within the Ready Teacher Toolbox contain content that is included in CA’s proprietary Ready curriculum materials. These PDFs are provided to you on a limited permission basis. While you may download PDFs to your computer for your own reference, you may not post or share electronic copies of any PDF files.

    You also may not print, copy, or share any pages from the Read Aloud Trade Books (available only in reading at grades K and 1). In limited quantity and for use in your own classroom, you may print and/or make copies of student and teacher pages from other PDFs on the Ready Teacher Toolbox. Copies of these materials must include all copyright, trademark and other proprietary rights notices contained on the original pages from which the copies were made. Except as specified in this paragraph, you may not reproduce, upload, post, transmit, download or distribute any part of the Ready Teacher Toolbox content or information.

  • Where can I access the correlations and other resources found in the front matter of my Teacher Resource Book?

    Click on Program Implementation at the top left of the page to see correlations and other resources found in the front of your Teacher Resource Book.

  • Where are the Ready Assessments and Assessment Teacher Guides on the Teacher Toolbox?

    Click on Ready Assessment Book to see the Ready Assessments and Teacher Guides.

  • Why do I sometimes see two versions of the same lesson in the Toolbox?

    When we update our Ready print materials, we keep our older materials active on the Toolbox for one additional school year, to support teachers who might be using those older materials in their classrooms, and prefer to use a Toolbox version that matches their books.

  • Why are some of the Interactive Tutorials missing?

    In some cases, there are no Interactive Tutorials to support a particular Ready lesson. We are always working to boost our coverage of the standards, and we plan to include more Interactive Tutorials in the future.

  • Why do some of the Interactive Tutorials seem to be different than the Ready lesson they accompany?

    Some Interactive Tutorials have different titles than the Ready lessons, often because they teach the same standards and skills in different ways or through slightly different content. Some tutorials are also designated as prerequisites and are intended to teach prerequisite skills to the standard in question. In these cases, the titles may not match at all.

    Additionally, some Interactive Tutorials are correlated with more than one Ready lesson. The intent is to show that these tutorials can support the teaching of more than one Ready skill.

  • How come only some Tutorials can be paused?

    New Toolbox Interactive Tutorials come with a Pause Feature.  Lessons which are new and have the pause feature enabled can easily be discerned by their thumbnail images, which are blue and feature the characters Plory and Yoop.

  • Is there a student subscription?

    No, the Toolbox is a teacher resource designed to provide teachers access to the Ready lessons and additional resources, which can be used for whole class or small groups to help differentiate instruction. Lessons are conveniently organized to match your print materials, making it easy to find additional resources for teaching the skills and standards associated with each lesson. All of these resources are perfect for use with any interactive whiteboard or other computer projection screen.
