A description of RtI tiered instructional resources for the program is included in the Teacher’s Program Overview for each grade. The following are examples of tiered instructional support found online for each lesson.

Tier 1 ongoing Intervention includes the following resources that can be used during the lesson:

• Prevent Misconceptions. During the Understand & Apply, a remediation strategy is included to address a common misconception about the lesson concept.
• Error Intervention (If... Then...). During Practice & Problem Solving, error intervention identifies a common error and provides a remediation strategy.
• Reteaching Set. This set is provided before independent practice to develop understanding prior to practice.
• MathXL for School: Practice & Problem Solving, during the lesson, includes personalized practice for the Practice & Problem Solving portion of the lesson, along with Additional Practice or Enrichment; auto‐scored with on‐screen help, including Help Me Solve This and View an Example tools, tutorial videos, Math Tools, and one‐click animated glossary access.

Tier 2 strategic intervention includes the following resources that can be used at the end of the Lesson:

• Intervention Activity. This supports teachers working with small groups of struggling students.
• Reteach to Build Understanding. This provides guided reteaching as a follow‐up to the intervention activity.

Tier 3 intensive intervention instruction is delivered daily outside of the core math instruction, often in a one‐to‐one situation. Skills Review & Practice scaffolded instruction, for example, can be used for this purpose,

• Variety of Instructional Strategies.
• Multisensory instruction is provided in online Explore & Reason/Model & Discuss/Critique & Explain activities that include audio and visual learning.

enVision A|G|A is designed to achieve a coherent progression of mathematical content within each course and across the program, building lesson to lesson. Every lesson includes online practice instructional examples as the progression of topics builds, allowing students additional practice with these skills and developing a deeper conceptual understanding.

At the beginning of every topic, teachers are provided with support for the focus of the topic, how the topic fits into an overall coherence of the grade and across the grades, the balance of rigor in the topic, and how the practices enrich the mathematics in the topic. Carefully designed learning progressions achieve coherence across grades.

Coherence is supported by common elements across grades, such as Thinking Habits questions for math practices and diagrams for representing quantities in a problem. Coherence across topics within a grade is the result of developing mathematics as a body of interconnected concepts and skills. Across lessons and standards, coherence is achieved when new content is taught as an extension of prior learning–developmentally and mathematically. (For example, Model & Discuss/Explore & Reason/Critique & Explain at the start of lessons engage students in a problem-based learning experience that connects prior knowledge to new ideas and sets them up for the new concepts they will encounter in Step 2 of the lesson: Understand & Apply.

Look Back! and Look Ahead! connections are highlighted in the Coherence part of Topic Overview pages in the Teacher’s Edition.

The Topic Background: Rigor page shows teachers how areas of rigor will be addressed in the topic, and details how conceptual understanding, procedural skill and fluency, and application build within each topic to provide the rigor required.

On the first page of every lesson, the Lesson Overview includes sections titled Focus, Coherence, and Rigor. The Rigor section highlights the element or elements of rigor emphasized in the lesson, which may be one, two, or all three. Features in every lesson support each element, but the emphasis will vary depending on the standard being developed for conceptual understanding, procedural fluency, and application during both instruction and practice, as described below:

• Explore
  Step 1 Explore supports coherence by helping students connect what they already know to a problem in which new math ideas are embedded. When students make these connections, conceptual understanding emerges. Problem-based learning provides students with opportunities for productive struggle and time to make connections to mathematical ideas and conceptual understandings. They can choose to represent their thinking and learning in a variety of ways. Online tools and manipulatives are available. Step 1: Explore activities are one of the following


• Model & Discuss Students are presented with a situation that requires them to engage with an element of the mathematical modeling process.
• Critique & Explain Students evaluate examples of mathematical reasoning and critique the reasoning as appropriate. In all instances, students are asked to construct mathematical arguments.
• Explore & Reason Students explore a mathematical concept and use reasoning to draw conclusions.


• Understand and Apply
  Step 2 Understand and Apply is designed to connect students’ thinking about the opening activity to the new ideas of the lesson. These concepts are presented through a series of visually rich example types purposefully designed to promote understanding. Conceptual Understanding examples present a key mathematical concept in the lesson to help students develop deep understanding of the mathematical content. Skill examples focus on helping students build fluency with skills. Finally, Application examples show students how mathematics can be used to solve real-world problems.


• Practice and Problem Solving
  Step 3 Practice & Problem Solving offers robust and balanced practice to solidify understanding. Students embark on a series of carefully sequenced and crafted exercises to apply what they just learned and to practice towards mastery. The design of the Practice & Problem Solving section is intentionally sequenced into four parts: Understand, Practice, Apply, and Assessment Practice.


• Assess & Differentiate
  Step 4 Assess & Differentiate features a Lesson Quiz and a comprehensive array of intervention, on-level, and advanced resources for all learners, with the goal that all students have the opportunity for extensive work in the state standards. Leveled practice with scaffolding is included at times. Varied problems are provided and math practices are identified as appropriate. Higher Order Thinking problems offer more challenges. Students have ample opportunity to focus on conceptual understanding and procedural skills and to apply the mathematics they just learned to solve a range of problems.
