Sixth graders discover that one-half, 0.5, and 50 percent are three ways of writing the same amount, and match common benchmark values across fractions, decimals, and percents.
Students will be able to…
A score of one-half, 0.5, and 50 percent all mean the same thing. Why three ways to write one amount, and how do you move between them?
Project this and match each fraction to the same value written as a decimal and a percent — tap a fraction, then tap its equivalents.
Tap any phase to open the teacher moves and student actions.
A test score of one-half, 0.5, and 50 percent all mean the same thing. Why do we have three ways to write one amount, and how do they connect?
