📘 Chapter notes
The key ideas of this chapter, answered through the six guiding questions. Read them with your textbook.
1What am I looking at?
Answer: Comparing objects by length and weight using everyday words and simple non-standard units.
2What are its main parts or ideas?
Answer: Length words: long, longer, longest, short, tall. Weight words: heavy, light, heavier, lighter.
3How does it work?
Answer: Place objects side by side from the same starting line to compare length; use a simple balance to compare weight — the heavier side goes down.
4Why is it important?
Answer: Comparing helps us choose things: the longer rope, the lighter bag.
5What happens if something changes?
Answer: A big object is not always heavier: a balloon is big but light, a stone is small but heavy.
6What should I remember for the exam?
Answer: Arrange objects in order of length or weight and measure with hand spans or footsteps.
