Lesson 25 Concept Development

Each rectangle represents 1 whole. Partition the first rectangle into thirds.

Write the whole as a fraction below it.

3/3 = 1 whole

Now partition the second rectangle into halves. Label the whole as a fraction below it.

2/2 = 1 whole

Now partition the third rectangle into wholes.

What do you mean? It is already a whole. That means 0 partitions!

1 whole as a fraction is to write it as 1/1

We didn’t split it into more parts, so the whole is still in 1 piece, and we’re counting that 1 piece.

Using a number line, tell the difference between 2/1 and 2/2

2/2 means one whole. 2/1 means 2 wholes.

1. Label the following models as a fraction inside the boxes.

2. Fill in missing whole numbers. Then rename the wholes in the boxes.

3. Explain the difference between these fractions using a number line, pictorial model, or words.
