Question

Explain how showing fractions with models and a number line are alike and different?

Positive fractions are to the right of zero, and negative fractions are to the left. Fractions increase as you go from left to right. They decrease as you go from right to left.

Answer 2

Showing fractions can be expressed in model and number line.
Using a model, you have to draw the number of parts (denominator) and shade the number of parts (numerator).

Using a number line, the line starts from 0 to the number of the denominator. You put a marker to the number that is the same as the numerator.

Both model and number line use the value of the numerator and denominator. What makes them different is how they are presented. Model can easily be understood compared to number line.
