What number should be written below the 2/12 bar?
(1
Write this number
12
on the transparent line and ask students to write it on their lines.
The "1" in this number is for the 1 whole bar and 2/12 is for the shaded
amount of the next bar. We call this number "1 and 2/12".
This type of number is a mixture of two types of numbers: the whole number
1 and the fraction 2/12. It is called a "mixed number." We can also write 1
and 2/12 as the sum 1 + 2/12.
Select a different orange bar that is not a zero bar or a whole bar, place it on
your line between 1 and 2 and write the mixed number for the bar.
Ask a few
students to describe their bar and give its mixed number. As they do, point to
the marks on the transparent line.
To avoid crowding on your number line between 1 and 2, we will just write
the mixed numbers: 1 and 2/12; 1 and 4/12; 1 and 6/12; 1 and 8/12; and 1 and
10/12.
Point to these marks on the transparent number line and write these
mixed numbers.
Why is the number 2 written on the number line?
(It is at the end of the
second bar and represents a length of 2 whole bars.)
