Comparing Fractions with Different Denominators
Students will compare two fractions with different numerators and different denominators by creating common denominators or numerators, or by comparing to a benchmark fraction.
Key Questions
- Justify why we must use the same whole when comparing two different fractions.
- Compare different strategies for comparing fractions, such as common denominators or benchmark fractions.
- Predict which of two fractions is greater without drawing a model, explaining the reasoning.
Common Core State Standards
About This Topic
Colonial life focuses on the everyday experiences of the people who settled in the early colonies. Students explore the challenges of building homes, growing food in a new climate, and establishing communities. This topic covers the roles of men, women, and children, providing a window into how different life was without modern technology. It aligns with standards about economic specialization and social history.
By comparing colonial life to their own, students develop a sense of historical empathy. They learn about the importance of cooperation and hard work in the survival of these early settlements. This topic is particularly effective when students can engage in simulations of colonial tasks or use station rotations to explore different aspects of daily life, from schooling to candle-making.
Active Learning Ideas
Stations Rotation: A Day in the Life
Set up stations representing colonial tasks: 'The Schoolhouse' (using hornbooks), 'The Kitchen' (churning butter or grinding corn), and 'The Workshop' (weaving or simple carpentry). Students rotate to try each task.
Think-Pair-Share: Colonial vs. Modern
Students look at a picture of a colonial chore, like fetching water from a well. They think about how we do that task today, pair up to discuss which way is harder and why, and share with the class.
Inquiry Circle: Colonial Needs
Groups are given a list of items (wool, wood, iron, seeds). They must research how a colonial family would turn these raw materials into finished products like clothing, houses, or tools.
Watch Out for These Misconceptions
Common MisconceptionColonial children just played all day.
What to Teach Instead
Explain that children were expected to work as soon as they were able, helping with chores, gardening, and caring for animals. A station rotation of colonial chores can quickly dispel the idea that it was all play.
Common MisconceptionAll colonists lived in the same kind of houses.
What to Teach Instead
Teach that housing varied by region and wealth. Some lived in log cabins, others in brick houses, and some in simple sod homes. Showing pictures of different colonial styles helps students see the diversity.

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.
More in Fractions: Equivalence and Operations
Visualizing Fraction Equivalence
Students will explain why fractions are equivalent by using visual fraction models, paying attention to how the number and size of the parts differ even though the fractions themselves are the same size.

Decomposing Fractions
Students will understand addition and subtraction of fractions as joining and separating parts referring to the same whole, and decompose a fraction into a sum of fractions with the same denominator.
2 methodologies
Adding and Subtracting Fractions
Students will add and subtract fractions with like denominators, including mixed numbers, by replacing mixed numbers with equivalent fractions, and/or by using properties of operations and the relationship between addition and subtraction.
