Task

Provide materials to the student.  Read the problem to the student:  Mrs. Gaddy’s students counted seeds from the pumpkin they cut open.  Each student grabbed a handful of seeds.  Lauren just counted 52 seeds but had some more to count.  What numbers will she say for the next 15 seeds?    

52, ___, ___, ___, ___, ___, ___, ___, ___, ___, ___, ___, ___, ___, ___, ___

Eva said it would be easier to count the seeds in groups instead of counting by ones.   How many groups of ten does she make?  How many leftovers?  How many seeds altogether?
