Comparing and Rounding Decimals
Students will compare two decimals to thousandths based on the meaning of the digits in each place and round decimals to any place.
Key Questions
- Differentiate between two decimal numbers based on their place values.
- Justify the process of rounding a decimal to a specific place.
- Predict the impact of rounding on the precision of a decimal number.

About This Topic
This topic explores the intellectual and social innovations of North American Indigenous peoples, including governance, agriculture, and oral traditions. A primary focus is the Iroquois Confederacy (Haudenosaunee), which provides a model of early democratic cooperation. Students also look at advanced farming techniques like the 'Three Sisters' (corn, beans, and squash) and the power of storytelling in preserving history and values without a written alphabet.
These concepts align with standards regarding the development of political systems and cultural identity. By studying these achievements, students see Indigenous peoples as active contributors to the foundations of American society. This topic comes alive when students can physically model the patterns of the Three Sisters garden or engage in a simulation of a Great Council meeting.
Active Learning Ideas
Simulation Game: The Great Council
Students represent different nations in the Iroquois Confederacy. They are given a community problem to solve and must use the consensus-building rules of the Great Law of Peace to reach a decision.
Inquiry Circle: The Three Sisters
In small groups, students research how corn, beans, and squash help each other grow. They create a 'living diagram' or poster showing the symbiotic relationship and why this was a scientific breakthrough.
Peer Teaching: Oral Tradition Storytelling
Students listen to a traditional Indigenous story and identify the moral or historical lesson. They then practice retelling the story to a partner, emphasizing the importance of memory and voice in history.
Watch Out for These Misconceptions
Common MisconceptionIndigenous people did not have 'real' governments.
What to Teach Instead
Many groups had highly structured systems, like the Iroquois Confederacy, which influenced later democratic ideas. A mock council meeting helps students experience the complexity of these political systems firsthand.
Common MisconceptionHistory only exists if it is written down.
What to Teach Instead
Oral traditions are highly accurate and disciplined methods of record-keeping. Comparing an oral account with a written one in a think-pair-share activity helps students value different ways of preserving the past.
