Understanding Part-Part-Whole
Students explore how numbers can be split into parts and how these parts combine to make a whole. This builds the foundation for solving number sentences.

5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
Unit PlannerMath Unit
Plan a multi-week math unit with conceptual coherence: from building number sense and procedural fluency to applying skills in context and developing mathematical reasoning across a connected sequence of lessons.
RubricMath Rubric
Build a math rubric that assesses problem-solving, mathematical reasoning, and communication alongside procedural accuracy, giving students feedback on how they think, not just whether they got the right answer.

Identifying Additive Patterns
Students look at sequences of numbers and identify the repeating additive rule. They explore patterns that skip count by tens, hundreds, and thousands.

Finding Missing Elements in Patterns
Students investigate incomplete number sequences and use their knowledge of additive rules to find the missing numbers.

Solving for Missing Numbers (Addition)
Students use part-part-whole relationships to find unknown numbers in addition equations. They balance equations to ensure both sides are equal.
