How to Use the Materials
Each Lesson and Unit Tells a Story
- the mathematical content of the lesson and its place in the learning sequence
- the meaning of any new terms introduced in the lesson
- how the mathematical practices come into play, as appropriate
- the mathematical purpose of the activity and its place in the learning sequence
- what students are doing during the activity
- what the teacher needs to look for while students are working on an activity to orchestrate an effective synthesis
- connections to the mathematical practices, when appropriate
Launch - Work - Synthesize
Each classroom activity has three phases.
During the launch, the teacher makes sure that students understand the context (if there is one) and what the problem is asking them to do. This is not the same as making sure the students know how to do the problem—part of the work that students should be doing for themselves is figuring out how to solve the problem. The launch invites students into the lesson and helps them connect to contexts that may be unfamiliar.
Student Work Time
The launch for an activity frequently includes suggestions for grouping students. This gives students the opportunity to work individually, with a partner, or in small groups.
During the activity synthesis, the teacher orchestrates some time for students to synthesize what they have learned. This time is used to ensure that all students have an opportunity to understand the mathematical punch line of the activity and situate the new learning within students’ previous understanding.
Each section in a unit includes an associated set of practice problems. There are 3 types of practice problems: pre-unit, lesson, and exploration. Teachers may decide to assign practice problems for homework or for extra practice in class. They may decide to collect and score it or to provide students with answers ahead of time for self-assessment. It is up to teachers to decide which problems to assign (including assigning none at all).
The practice problem set associated with the first section of each unit also includes several prior grade-level questions. These questions can be used to review prerequisite material from the previous grade or as a pre-unit assessment, if desired.
Lesson Practice Problems
The practice problem set associated with each section typically includes one question for each lesson in the section.
Each practice problem set also includes exploration questions that provide an opportunity for differentiation for students ready for more of a challenge. There are two types of exploration questions. One type is a hands-on activity that students can do directly related to the material of the unit, either in class if they have free time, or at home. The second type of exploration is more open-ended and challenging. These problems go deeper into grade-level mathematics. They are not routine or procedural, and they are not just “the same thing again but with harder numbers”.
Exploration questions are intended to be used on an opt-in basis by students if they finish a main class activity early or want to do more mathematics on their own. It is not expected that an entire class engages in exploration problems, and it is not expected that any student works on all of them. Exploration problems may also be good fodder for a Problem of the Week or similar structure.
Instructional Routines are designs for interaction that invite all students to engage in the mathematics of each lesson. They provide opportunities for students to bring their personal experiences as well as their mathematical knowledge to problems and discussions. They place value on students’ voices as they communicate their developing ideas, ask questions, justify their responses, and critique the reasoning of others.
Instructional routines have a predictable structure and flow. They are enacted in classrooms to structure the relationship between the teacher and the students around content in ways that consistently maintain high expectations of student learning while adapting to the contingencies of particular instructional interactions (Kazemi, Franke, & Lampert, 2009). A finite set of routines support the pacing of lessons as they become familiar and save time in classroom choreography, so students can spend less time learning how to execute lesson directions, and more time on learning mathematics.
There are two types of Instructional Routines used in the materials: Warm-up Routines and Lesson Activity Routines. A list of the routines within each type is outlined in this table.
|Warm-up Routines||Lesson Activity Routines|
|Act It Out||MLR1: Stronger and Clearer Each Time|
|Choral Count||MLR2: Collect and Display|
|Estimation Exploration||MLR3: Critique, Correct, and Clarify|
|How Many Do You See?||MLR4: Information Gap|
|Notice and Wonder||MLR5: Co-craft Questions|
|Number Talk||MLR6: Three Reads|
|Questions About Us||MLR7: Compare and Connect|
|True or False?||MLR8: Discussion Supports|
|What Do You Know About _____?||5 Practices|
|Which One Doesn’t Belong?||Card Sort|
Each lesson begins with a Warm-up Routine intentionally designed to elicit student discussions around the mathematical goal of the lesson. The Lesson Activity Routines embed structures within the tasks of the lessons that allow students to engage in the content, and collaborate in ways that support the development of student thinking and precision with language. Math Language Routines (MLRs) are Lesson Activity Routines that provide additional structures in order to support English learners. MLRs are written into each lesson, either as an embedded structure of a lesson activity in which all students engage, or as a suggested optional support specifically for English learners.
