Adapted Mind Math is a web-based educational resource comprised of 15,000 explanatory videos and more than 300,000 distinct problems. Adapted Mind Math, used by educators and parents around the world, introduces students to a number of mathematical topics, including early multiplication.
While some children take to their multiplication tables with relative ease, others may struggle, particularly when it comes to multiplying larger numbers. The nines table, in particular, can pose a challenge to young mathematicians. One useful trick teachers and parents might consider introducing to children involves the final digit of each sum on the nines table. These numbers begin at nine and count backwards to zero before starting over again. For example, nine multiplied by one equals nine, while nine multiplied twice is 18. The following solutions of nine multiplied by three, four, and five, meanwhile, are 27, 36, and 45, respectively. This trend continues through nine multiplied by 10, which is 90, before beginning again at nine multiplied by 11.
Students may also benefit from using their hands when trying to learn the nines table. Children should begin by placing both hands palms down on their desks with all 10 fingers displayed. When solving for nine multiplied by six, children should hold down their sixth finger, the thumb on the right hand. This leaves five fingers on one side and four on the other, providing the correct solution of 54. This trick, of course, can only be used up to nine multiplied by 10.
