1.OA.C.5 Worksheets: Counting to Add
Home › Common Core › 1st Grade Math Standards › 1.OA.C.5 Worksheets
1.OA.C.5 (Operations and Algebraic Thinking): Connect counting on and counting back with adding and subtracting.
About this standard
This standard links counting to adding and subtracting: counting on 2 from 6 gives 8, and counting back 3 from 9 gives 6. A number line makes each count a visible hop. Practice both directions with Addition on a Number Line and Subtraction on a Number Line, then aim for facts from memory at 1.OA.C.6.
