About this worksheet

Teen Number Missing Parts gives kindergarten students a focused page for a skill that parents and teachers often need as its own printable worksheet. This gives teachers a missing-part teen-number page rather than another count-and-name page. Students should connect the ten-frame picture to the equation 10 + ones. The items rotate through several question types so the page is not just the same prompt with different numbers or words. Students complete teen number equations and identify missing ones from ten-frame models. Support versions keep the reading load, numbers, or choices friendlier while preserving the same thinking. Standard versions match everyday classroom practice. Challenge versions add a closer distractor, an extra reasoning step, or less familiar examples. Before answering, students should say what the question is asking, point to the evidence, and check that the answer fits the exact skill named in the title.
