Lesson 1
3rd Grade
Science
How can we tell whether something is living?
Students will use observation, discussion, and evidence to identify the characteristics of living organisms.
Instead of beginning with a lecture, students work in small groups to examine photographs and real-world objects. Each group sorts items into "living," "nonliving," and "not sure," then explains its reasoning.
As students share their ideas, we discuss why some examples are more challenging than others (for example, seeds or dormant plants), encouraging students to support their thinking with evidence.
Students then investigate the characteristics shared by living things and revise their original classifications before completing a short reflection explaining how their thinking changed.
Visual supports
Collaborative discussion
Multiple ways to demonstrate understanding
Extension questions for advanced learners
Students use tablets to photograph examples of living and nonliving things around the classroom and record observations in a shared digital journal.
Students write a brief explanation identifying one living and one nonliving object and explaining their reasoning using evidence from the lesson.
Why I Designed It This Way
I wanted students to begin by making their own observations before introducing formal vocabulary. This encourages curiosity, gives every student an opportunity to contribute, and demonstrates that changing your mind in light of new evidence is an important part of learning.
Lesson 2
4th Grade
Literacy
How do we know whether we can trust what we read?
Students will learn to identify clues that help determine whether a source of information is reliable by asking thoughtful questions, evaluating evidence, and supporting their conclusions.
The lesson begins with students working in small groups to examine three short articles about the same topic. One comes from a reputable children's news source, one is a personal blog, and one contains intentionally misleading or exaggerated information.
Without being told which source is "correct," students discuss questions such as:
Who wrote this?
What evidence is provided?
Does the author seem trustworthy?
How can we tell?
Each group records its observations before sharing its reasoning with the class. Together, we compare the different sources and identify characteristics that make information more or less reliable.
Students then revisit their original opinions, revise their thinking if necessary, and create a short checklist they can use whenever they encounter new information online or in print.
Students work collaboratively so they can learn from one another's ideas.
Articles are provided at multiple reading levels while addressing the same essential question.
Graphic organizers help students organize their thinking.
Extension activities challenge advanced learners to identify subtle forms of bias or missing evidence.
Students use classroom devices to investigate an additional online article and apply their source evaluation checklist. Technology is used to strengthen critical thinking rather than simply deliver information.
Students evaluate a new article independently and write a brief explanation defending whether they believe it is a reliable source, citing specific evidence to support their reasoning.
I believe one of the most valuable skills students can develop is the ability to think critically and evaluate information for themselves. Rather than beginning with a lecture about reliable sources, this lesson encourages students to ask questions, examine evidence, discuss their ideas with classmates, and refine their thinking through reflection. By allowing students to construct understanding together, the lesson builds curiosity, confidence, and the habits of mind they'll continue using long after they leave my classroom.
Lesson 3
5th Grade
Mathematics
Is there more than one correct way to solve a math problem?
Students will solve multi-step word problems involving fractions using a variety of strategies while explaining and defending their mathematical thinking.
The lesson begins with a real-world scenario:
A class is planning a picnic. Different groups have prepared fractional portions of sandwiches, fruit, and snacks. Can we determine whether there is enough food for everyone?
Rather than demonstrating a procedure first, students work in small groups to develop their own solution strategies. Some may draw visual models, others may use equations, number lines, or area models.
As students work, I circulate through the classroom, asking questions such as:
Why did your group choose this strategy?
Can you explain your thinking?
Is there another approach that would also work?
How do you know your answer is reasonable?
Groups then present their solutions to the class, comparing different methods and discussing the strengths of each approach. Together, we identify common mathematical principles that connect the various strategies.
Students conclude the lesson by reflecting on whether seeing multiple approaches changed or strengthened their own understanding.
Students choose from multiple problem-solving strategies that match their learning preferences.
Visual models, manipulatives, and graphic organizers are available for students who benefit from additional supports.
Collaborative groups encourage peer learning and mathematical discussion.
Extension problems challenge advanced learners to compare the efficiency of different solution methods or create their own word problems.
Students use interactive virtual fraction models to test and visualize their solutions before presenting their reasoning. Technology serves as a tool for exploration and deeper conceptual understanding rather than simply providing answers.
Students independently solve a new multi-step fraction problem and write a brief explanation describing not only how they solved it, but why their strategy works. Emphasis is placed on mathematical reasoning and clear communication in addition to arriving at the correct answer.
Mathematics is more than following a set of procedures; it's a way of thinking. I want students to see that many problems can be solved in multiple valid ways and that explaining their reasoning is just as important as finding the correct answer. By encouraging students to compare strategies, ask questions, and learn from one another, this lesson builds confidence, strengthens conceptual understanding, and reinforces the idea that mistakes and different perspectives are valuable parts of the learning process.
