The similarities between ten-frames and base-ten blocks when used to add a 2-digit number and a 1-digit number

In this lesson, students use what we know about adding with ten frames to find how we can add with tens and ones blocks. Students discover how tens frames and counters are like tens and ones blocks. Directs partners to work together to create and solve real life situation story problems together , one partner using tens frames and the other using tens and ones blocks, and then compare their efforts and check for accuracy in their math journals.
