This mostly self-checking Easel activity introduces, practices, reviews, and quizzes students on multiplication by 2. The introduction explains the special properties of multiplying by 0 and 1 and shows each of the 2s facts as groups (1 group of 2) and sets (2 sets of 1). It also shows multiplication as repeated addition, arrays and facts families. This is the only section that has the students type in the correct answer and is not self-checking. The practice section is a drag and drop puzzle. T
