About These Materials
These materials were created by Illustrative Mathematics. They were piloted and revised in the 2019-2020 and 2020-2021 school years.
Each grade level contains 8 or 9 units. Units contain between 8 and 28 lesson plans. Each unit, depending on the grade level, has pre-unit practice problems in the first section, checkpoints or checklists after each section, and an end-of-unit assessment. In addition to lessons and assessments, units have aligned center activities to support the unit content and ongoing procedural fluency.
The time estimates in these materials refer to instructional time. Each lesson plan is designed to fit within a class period that is at least 60 minutes long. Some units contain optional lessons and some lessons contain optional activities that provide additional student practice for teachers to use at their discretion.
Teachers can access the teacher materials either in print or in a browser as a digital PDF. When possible, lesson materials should be projected so all students can see them.
Many activities require blackline masters of recording sheets, game boards, or cards that teachers need to photocopy or cut up ahead of time. Teachers might stock up on two sizes of resealable plastic bags: sandwich size and gallon size. For a given activity, one set of cards can go in each small bag, and then the small bags for one class can be placed in a large bag. If these are labeled and stored in an organized manner, it can facilitate preparing ahead of time and reusing card sets for multiple activities.
There are a few blackline masters that we recommend teachers copy once and laminate for frequent use. These blackline masters are provided as a Material to Copy in each grade in the first lesson or center in which they appear with a note, such as: “Number Cards are provided as a blackline master. Students will continue to use these throughout the year. Consider copying them on cardstock or laminating them and keeping them organized to be used repeatedly.” When these materials are needed again in that grade in lessons or centers, they are listed as a Material to Gather and the blackline master is not provided.
This list shows where these blackline masters first appear in each grade, when applicable.
