Help 3rd grade students solve elapsed time problems with a complete visual number-line intervention bundle. This bundle gives teachers ready-to-print task cards, missing start/end time practice, across-the-hour cards, word problems, error analysis, test prep, small-group mats, and a complete intervention system. Each resource uses the same Start -> Jump -> End routine so students learn to model time on an open number line, choose benchmark jumps, explain their reasoning, and check answers
