Gr 3_NBT_Rounding_ThinkPairShare_Construct

This task requires third grade students to find a halfway point between two numbers (30 and 40) and construct an argument explaining how he or she knows that their number is the halfway point. Students are also asked to engage in a think-pair-share in which they discuss the process with a partner. The task may lead to a good discussion about medians or about rounding and how to round to the nearest tenth when a number ends in a 5.
