Students add (sums below 12) using a number line. This adds another modality of understanding addition. Students can start with the higher number and count on by using the visual number line.
Common Core understanding requires students to draw, build, explain, etc., and emphasizes the importance of using a number line repeatedly. Students can make up their own number sentences as well.
This assignment will lead nicely into using different adding strategies (decomposing numbers etc.) and with different addition properties later on.
