There are more than 20 references to number lines in the Common Core Standards. This double-sided 18' by 24' visual is a powerful connection to Kim's Number Line. It will allow the elementary classroom teacher opportunities to have students visualize solving problems on the number line. The skills that can be reinforced with this tool include alternative algorithms for regrouping, subtracting across zeros, rounding practice, addition, subtraction, multiplication and division, fractions and decimals, elapsed time and measurement techniques.
