To practice these math problems of 2MDB6 worksheets, students are required to generate measurement data by representing whole numbers as lengths from 0 on a number line and know that the points corresponding to the numbers on the number line are equally spaced by using a number line to represent whole number sums and differences of lengths within 100. The main objective of these 2.MD.B.6 problems, answers and work with steps is to make students to relate addition and subtraction to length. Users can directly refer the answer key to verify the work with steps for the corresponding practice problems given in the 2.MD.B.6 activities under common core state standards for 2nd grade mathematics.
