We use words like bigger, smaller, longer, shorter, taller, heavier, and lighter to compare objects. These words help us describe and measure the world around us.
Look at two objects at the same time. Use size words to describe how they are different.
Length tells us how long or short something is. We can compare objects by placing them side by side to see which one is longer or shorter.
Place objects next to each other with their ends lined up. This makes it easier to see which one is longer or shorter.
Height tells us how tall or short something is. We can compare by standing objects up to see which is taller or shorter.
Stand objects on the same surface when comparing height. This makes it clear which one is taller.
Weight tells us how heavy or light something is. We can compare objects by holding them or using a balance scale.
Use two hands or a balance scale to feel which object is heavier or lighter.
We use size words every day to make choices and solve problems. Think about what you are comparing and choose the correct word to describe it.
Always compare two objects carefully. Think about whether you are talking about length, height, or weight.
