This printable fractions worksheet helps 1st graders to enhance their understanding of fractions. It builds upon their mastery of the concept of one-half and introduces them to one-fourth. All your 1st grader needs to do is circle one-fourths of each set of insects – but his basic division skills need to be shipshape for that. Is he up to the challenge? If he is, have him move on to other 1st Grade Math Worksheets.
