Samenvatting
Durable plastic "flashcards" consist of a "fact family." One number, marked with an asterisk, is the sum or product of the other two numbers. Practice facts and develop an understanding of relationships between operations by covering one number with a thumb. Each set of 36 is packaged with a reclosable plastic bag.
