Major Mathematics Ideas:
Convert fraction to decimal to percent and vise versa
Can you show 0.3 and 0.5 on a hundredths grid? Why or why not?
Can you show me 0.65 and 0.40 on a tenths grid? Why or why not?
What would a hundredths grid look like if each square of the grid were
divided into eight equal parts? How many parts would the new grid have?
What is the fraction name for the smallest part of this new grid?
-Ask students: What is a fraction, decimal and percent? In other words
what does it really mean to be a fraction, decimal and percent?
-Ask students: What does a fraction, decimal, and percent have in
-Ask questions to help students interpret the chart.
Do you see any similarity to the names of the place values about the 1?
What are your predictions for the next few lines of the chart if you were to
extend it both to the left, right?
-Give students a chance to answer the questions and then put in the
following numbers in the places using a white board and markers.
-Have several students read the decimal and then write out the standard
form into word form on the white board. Then have the students come up
with some numbers.
Hand out work sheet and have students to complete the three questions on
their own. Give them about five minutes
Directions: fill in the correct fraction, decimal and percent in the square below the grid
then fill in the grid with the correct picture.

-Have students to change the order to fractions, decimal and percent. Give
them some time to play with it. (About 5 minutes)
-Give students a fraction and have them put in the decimal then the percent.
Continue this switching from fraction to decimal and then to percent. Make
sure they press reset after each answer. Have the students give some
