M2.4.2 For the adult

One part: halves, quarters, thirds, fifths

Eight is more than four. So is 1/8 more than 1/4?

What this chapter teaches

The bottom number names how many equal parts make the whole, and one part of them is a unit fraction. More parts means smaller parts, so one eighth is smaller than one quarter.

Three questions to ask

There is no one right wording. Listen for the idea.

  1. Which is bigger, one quarter of a bread or one eighth of the same bread, and how do you know?
  2. What does the bottom number of a fraction tell you?
  3. Why do you think the pieces get smaller when a bread is cut into more parts?

After the chapter, the learner can

  • Name one equal part as a half, quarter, third or fifth
  • Say what the bottom number of a fraction tells you
  • Tell which of two parts is smaller, such as 1/8 and 1/4

What they copy into their notebook

The bottom number says how many equal parts. One part of 4 is 1/4. More parts means smaller parts, so 1/8 is smaller than 1/4.
