This file contains three flashcard formats for learning the mental math strategy of doubles. The flashcards are designed for independent use. The first format is designed for students who are just beginning to understand addition, and include teddy bear pictures for the student to count. The second format is for students who understand the strategy of adding on, and only include teddy bears for the second numeral. The third format is designed for students who simply need additional practice with remembering doubles, and does not include objects to count. A page formatted with the doubles addition facts with the answer is included to print on the back of each set of flashcards to make the cards self checking. The immediate reinforcement of seeing the correct answer will help students learn these facts more rapidly.
This flashcard set reinforces Common Core standards K.OA.3, 1.OA.6, and 2.OA.2.
This set is also available with a Monkey Theme. Watch for games and activities to reinforce the strategy of doubles... coming soon!
