NLVM Fraction Bars

This week I focused on the NLVM fraction bars.
Fractions are something we cover briefly in Kindergarten.
I felt this Virtual Math Manipulative is a good game for reinforcement of new material.

How to play:
1) First set the desired length with the up and down arrows.
2) Click the new button. You may add multiple bars by repeatedly clicking the new button.

In this game you can choose any colored bars a variety of lengths from 1 to 10.

This game can be modeled to your students first.
Students can be assigned to computers. Teacher can create a table using word.
For example if you are working on fractions (halves, thirds or forths) have 4 columns; two rows.
Ask students to show a half, by coloring the table. They may use the fraction bar games to help.
