Number Lines to Represent Percents

I am following the blog Adventures at the Pond (author has some great stuff!) and the following photo was posted on this blog. percents on a number line

This is an excellent alternate representation of a concept. I do not know how the author would present this in class but here’s what I would do. I would give the students the number line with the initial information and ask them to estimate the total minutes – no calculation.percents on a number line part 1

I would then explain the factor in the percent part (multiply by 5 to get to 100%) and lead the students to carry this factor over into the minutes:percents on a number line part 2This would lead into proportions nicely. I would present the number lines and have the students work out problems using this approach first (Universal Design for Learning) then redo the problems using proportions.

    We approached our lesson and work for this concept in a similar way. We also connected it to a ‘double’ number line. It always amazes me to see the ‘light bulbs’ and ‘ah ha’ moments when connecting concepts to visual models. Thank you for sharing, linking, and discussing!
