Today we worked on identifying rational numbers. We learned that these are numbers that can be written as ratios or fractions. As decimals, they come in two forms - terminating and nonterminating with repeating digits. Students practiced p 48 #8-12 where they converted between fractions, decimals, and percents. We also practiced writing rational numbers on Kahoot.
