Area of Rectangles by Tiling
Students calculate the area of rectangles by tiling with unit squares and relating it to multiplication.
Key Questions
- Explain how tiling a rectangle with unit squares helps us understand its area.
- Analyze the relationship between the side lengths of a rectangle and its area.
- Construct a formula for finding the area of any rectangle.

Planning templates for Mathematics
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.

Motion and Transformation: Flips and Slides
Students explore how shapes move through flips (reflections) and slides (translations).

Motion and Transformation: Turns
Students explore how shapes move through turns (rotations) around a fixed point.

Partitioning Shapes into Equal Areas
Students divide shapes into parts with equal areas and express the area of each part as a unit fraction.

Understanding Area
Students are introduced to area as the amount of space a two-dimensional shape covers, measured in square units.
