In this activity we use a grid to help students think of different names for the same fraction. As they become familiar with a hundredths grid, they will find it easier to make connections between fractions and decimals.
list several different names for fractions represented by shaded rows in a hundredths grid.
Blank OHP transparency 10 x 10 grid, or blank 10 x 10 grid drawn on the black board with wet chalk (enabling shaded areas to be drawn in and erased with the grid remaining).
What fraction of the whole square has been shaded?
For example, if 4 rows have been shaded answers may include 4 tenths and 40 hundredths
Have students come up with as many names for the fraction as they can, asking them to explain their thinking.
What is half of 4 tenths? How did you know?
