Fractions describe parts of a whole — half a pizza, a quarter of an hour. Splitting things fairly is where fractions begin.
This lesson focuses on Halves of Shapes: split shapes into two equal parts and shade one half.
Split shapes into two equal parts and shade one half.
Key ideas
Equal parts
A fraction only makes sense if the parts are exactly equal — two uneven pieces are not halves, no matter how they look.
Halves of numbers
Sharing equally between two people gives each person half, so half of 12 is 6. Finding halves is really division by 2.
Key term — Half: One of two equal parts of a whole. Two halves make the whole again.
A rectangle is split into 4 equal parts. How many parts make one quarter?
1 — a quarter is 1 out of 4 equal parts.
Answer: 1 — a quarter is 1 out of 4 equal parts.
- Calling unequal pieces halves The pieces must be exactly the same size for halves, quarters or any fraction to be correct.
- Writing the fraction upside down The total number of equal parts goes on the bottom, not the top.
Practice
9 — 18 ÷ 2 = 9.
1/2 — two parts make bigger pieces than four.
12 — 24 ÷ 2 = 12.
5 — 20 ÷ 4 = 5.
