4 weeks of doubles + 2 fact practice within 20: 1 week of addition, 1 week of subtraction, and 2 weeks of mixed review (+/-). Each week includes a packet you can create with 4 practice pages, 1 assessment, and 1 bar graph students can use to record and monitor their own progress. In my classroom, students complete these within 2 minutes using a timer. Includes implementation suggestions if you wish.
I have found that implementing fact practice this way increases student motivation and engagement. It is also a perfect opportunity for students to assess and monitor their own progress which administrators love! Create packets for math centers, homework, or whole class fact practice... whatever works for you and your class.
