Compare Objects: Length and Height
š Who is taller? Which train is longer? Let's measure up and compare the size of different objects using our math eyes.
Concept
When we compare the sizes of things, we use special words. šÆ **Height (How Tall):** When things stand up (like a tree, a person, or a building), we measure their **height**. * We use the words: **Tall, Taller, Tallest** or **Short, Shorter, Shortest**. * "The girrafe is taller than the zebra." šÆ **Length (How Long):** When things lay flat on the ground (like a snake, a stick, or a road), we measure their **length**. * We use the words: **Long, Longer, Longest** or **Short, Shorter, Shortest**. * "The yellow pencil is longer than the blue pencil." **Important Rule:** To compare two things, you MUST line up their starting points perfectly so it's a fair comparison!
Try it
Let's compare sizes! **Instructions:** Read the sentence and pick the right comparing word. **1. A skyscraper is _________________ than a house.** (Taller / Shorter / Longer) **2. A new, unsharpened pencil is _________________ than a pencil you used all year.** (Taller / Longer / Shorter) **3. An ant is _________________ than an elephant.** (Taller / Shorter / Longer) **4. A school bus is _________________ than a bicycle.** (Longer / Shorter / Taller) **Challenge Question:** Three trees are in a yard. An oak tree is taller than a pine tree.
