Partitioning Shapes into Halves & Fourths — Answer Key
Part A: Trace the Words
Trace each word carefully by following the dotted lines.
1. half
2. fourth
3. equal
4. part
5. whole
6. share
Part B: Fill in the Blank
Write the missing word or number on each line.
1. A shape split into 2 equal parts has two halves.
When a shape is cut into 2 equal parts, each part is called a half, so together there are two halves.
2. A shape split into 4 equal parts has four fourths.
Splitting a shape into 4 equal parts makes four fourths, because each piece is one of four equal parts.
3. Each half of a shape is an equal part.
Halves must be equal parts, meaning both pieces are exactly the same size — if one is bigger, they are not halves.
4. Cut a circle into 2 equal pieces, each piece is one half.
Cutting a circle into 2 equal pieces means each piece is one half of the whole circle.
Part C: True or False?
Read each statement. Circle True or False.
1. A square cut into 2 equal parts shows halves.
True False
This is true because 2 equal parts are always called halves, no matter what shape you start with.
2. A circle split into 3 equal parts shows fourths.
True False
This is false because fourths need 4 equal parts, not 3 — 3 equal parts are called thirds.
3. Each fourth of a shape is the same size.
True False
This is true because all four pieces in fourths must be the same size, or they are not really fourths.
