Partitioning Rectangles into Rows and Columns
Partitioning a rectangle into rows and columns of same size squares to count the total.
Key Questions
- How does tiling a rectangle help us understand its total size?
- What is the connection between partitioning a rectangle and the addition of equal groups?
- Why must the squares used for tiling be the exact same size?

About This Topic
American symbols and landmarks are the visual representations of the nation's values and history. In this topic, students identify the flag, the Statue of Liberty, the Liberty Bell, and the White House, and explain what they represent (like freedom, bravery, and leadership). This aligns with C3 standards for identifying and explaining the importance of national symbols and holidays.
Learning about these symbols helps students develop a sense of national identity and understand the shared ideals that unite a diverse population. It also provides an opportunity to discuss how symbols can mean different things to different people. Students grasp this concept faster through structured discussion and peer explanation, as they can share what these symbols mean to them and their families.
Active Learning Ideas
Inquiry Circle: Symbol Detectives
Small groups are given a photo of a landmark and must find three 'clues' in the image that tell a story about its meaning (e.g., the torch on the Statue of Liberty).
Think-Pair-Share: Designing a New Symbol
Students discuss a value they think is important (like kindness or nature) and work with a partner to design a new symbol that represents it.
Gallery Walk: Landmark Tour
The classroom is set up with 'stations' for different landmarks; students use a 'passport' to collect facts at each stop and draw a quick sketch.
Watch Out for These Misconceptions
Common MisconceptionThe Statue of Liberty was a gift from England.
What to Teach Instead
It was actually a gift from France to celebrate American independence. A 'Friendship Map' activity showing the connection between France and the US helps clarify this historical fact.
Common MisconceptionSymbols have always looked the same.
What to Teach Instead
The American flag, for example, has changed many times as more states were added. Showing a 'Flag Timeline' helps students see how symbols can evolve along with the country.

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.
