Division Concept of a Fraction

We explored the division model a bit in egg-carton fractions; It's usually about about sharing groups of whole units equally, rather than one whole, or unit, equally. (That's the part-to-whole model.)

 We explore this a little with folded paper strips. Soppose you had a plain paper strip 3 units long. How would you determine what ³/₄ of a unit is?

Try these for getting some practice:

• Fold a 7 linear unit paper strip. Show what ⁷/₃ liner units would be.
• Suppose you had a strip that was ⁴/₇ linear units long.How could you use to form a length of 4 linear units?
• Suppose a 13-square-unit sheet of notebook paper is divided into 6 congruent parts. How could you find the area of one part? two parts? four parts?

In the next lesson, we'll look at some fraction and decimal relationships.
