Fractions Intro — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. A rectangle cut into 2 equal parts has two halves.
When a rectangle is divided into 2 equal pieces, each piece is a half. Together they are called halves.
2. If no one cuts the cake, it is still whole.
If nobody cuts the cake, it stays whole because nothing has been taken away or divided.
3. To split a treat fairly, make equal parts.
Splitting a treat fairly means making parts that are the same size. Equal parts keep sharing fair for everyone.
4. Half of 2 grapes is 1 grape.
If you have 2 grapes and split them into 2 equal groups, each group has 1 grape. That is half of 2.
5. A whole has no missing pieces.
A whole is complete with nothing taken away. That means there are no missing pieces at all.
6. Two halves make one whole.
Two halves are the two equal parts that make up one whole. Put them together and you get the full shape back.
7. When you fold paper in half, you see 2 equal parts.
Folding paper in half lines up both sides perfectly, which shows you 2 equal parts that are the same size.
8. One half and one half is the same as one whole.
One half plus one half fills up the entire shape. Together they equal one whole.
9. Cutting a shape into equal parts makes fractions.
Fractions are made by cutting a shape into equal parts. Each part is a fraction of the whole shape.
