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.
