Smart Number Lines

Found In: math

I use number lines to help my 4th-grade students understand fractions, decimals, and temperature, since rulers and thermometers are based on number lines. I use different types of number lines – including those that represent rulers and thermometers – on my Smart Board, and my students have either paper copies or the objects on their desk to manipulate. Even though technology has changed over the years, these continue to be helpful tools to visualize abstract ideas. We still see the use of number lines on state tests, so it is helpful for students to have background in using them.
