How we explain it

Children can open this short lesson before they practice.

  1. The main idea is what the whole passage is mostly about. Details support it.
  2. To infer, put clues from the text together with what you already know.
  3. A good summary gives the main idea and the key details in a few words.

Example: Kenji draws a cake with candles on a card for his grandmother and wraps a present. What is the occasion most likely? Clues: a cake with candles, a card, a present. Those clues usually go with one kind of party. Answer: his grandmother’s birthday

  5. Question 5

    What is the main idea of this passage?

    Nature's Engineers

    Beavers are sometimes called nature's engineers. An engineer is someone who designs and builds things, and beavers are amazing builders.

    Using their strong front teeth, beavers cut down small trees and branches. They pile the wood across a stream and pack the gaps with mud and stones. This dam slows the water and makes a deep pond.

    In the pond, beavers build a home called a lodge. Its entrance is underwater, which helps keep the family safe from predators such as wolves.

    Beaver ponds help other living things, too. Ducks, frogs, fish and moose often visit or live in the wetlands that beavers create.

    • Wolves are predators
    • Beavers have strong front teeth
    • Beavers are skilled builders whose work changes the land around them
    • Ducks and frogs live in ponds
