K.CC..4. Math Number After task box. Designed to fit into a index card holder, this set includes both a beginner or supported set and a regular set. This can be used for extra practice or as an assessment tool. Data collection cards are included with the set to match the content. Use these to target IEP goals, provide extra practice after a skill is taught in class or even for home support. Students are required to count a group of objects, write the number and then write the number that comes after.
