Geometry and Fractions: Shapes and Parts · Weeks 28-36

Counting Tiled Squares

Students count the total number of same-size squares that tile a rectangle by rows and by columns.

Key Questions

  1. Explain how counting by rows and counting by columns both lead to the same total number of squares.
  2. Analyze the relationship between the number of rows, columns, and the total number of squares.
  3. Predict the total number of squares if a rectangle has 3 rows and 4 columns.

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 planner

Math 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.

rubric

Math 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.
