Ratios and Rates
Intro to Ratios
Students will be able to define a ratio as a way of relating and comparing two quantities as well as write ratios as a fraction (a/b), a:b, or in words – a to b. In addition, students will be able to model a ratio using a tape diagram and write a ratio as a fraction.
Understand and be able to identify a part vs a whole when looking at two quantities.
Differentiate your instruction by grouping your students by their needs and choose the most effective activity for each group
Challenge Your Students
Remind students that ratios can be written as a fraction, but unlike regular fractions, which only compare a part relative to its whole, a ratio can compare a part to its whole or a part to another part.
Students sometimes assume that the denominator in a ratio is the quantity of the whole, when it may be another part.
Have students work together to correct each other’s work
