Comparing Weights: Heavier or Lighter
Let's find out which objects are heavy and which are light. We will hold different things in our hands and use a simple balance to compare their weights.
About This Topic
Let's find out which objects are heavy and which are light. We will hold different things in our hands and use a simple balance to compare their weights.
Key Questions
- Compare a book and a feather; explain which one is heavier and how you know.
- Identify which side of a simple balance will go down if you place a duster on one side and a piece of chalk on the other.
- Explain why it is easier to lift a balloon than a brick.

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.

Comparing Sizes: Taller, Shorter, Bigger, Smaller
Let's look at objects around us and find out which ones are bigger, smaller, taller, or shorter. We will learn to compare things by their size.

Measuring Length with Non-Standard Units
How long is your desk? Let's find out by using our hand spans, pencils, or paper clips to measure different objects in our classroom.

Ordering by Length: Longest to Shortest
We can arrange things in order from the longest to the shortest, or the shortest to the longest. Let's practice ordering different objects like crayons and ribbons.

Ordering by Weight: Heaviest to Lightest
Just like with length, we can arrange objects in order from the heaviest to the lightest. Let's try ordering a few items from our school bags.

Understanding Time and Sequence
Let's learn about the different parts of the day. We will talk about what we do in the morning, afternoon, and night, and put our daily activities in the correct order.
