Addition to 20 Check-in

It's time to check those addition skills! In this worksheet, students will be asked to solve 12 problems by finding the sum of the two addends. This resource includes problems with two one-digit addends and problems with a two-digit addend and a one-digit addend. All sums are within 20. 

Use this worksheet to assess first and second graders' abilities to add within 20. Students will work on their addition fact fluency and automaticity so that they can solve simple addition problems with speed and accuracy. These skills will come in handy both inside the classroom as students learn trickier math, and outside the classroom in everyday life!
