Hello Andy, I am Leonito Fabian from the Philippines and am a mathematics teacher/trainor. In college, I'm teaching pure and applied mathematics in business. In basic education, I'm training elementary teachers speed mathematics using abacus, finger and mental mathematics. Chisenbop is really very helpful in teaching preschoolers 'counting' and graders basic addition and subtraction up to 99. DO YOU KNOW THAT OUR 10 FINGERS IS NOT JUST UP TO 99 BUT TO 9,999? You mentioned multiplication using fingers. Yes,our ten fingers can be used to multiply not just two 1-digit numbers but up to 99 times 99? I have developed these simple multiplication techniques through the years. I teach children the basic multiplication facts not by mere memorization as traditionally taught in schools but by different other methods like multiplication using reference numbers, mental and finger multiplication, multiplication using thc abacus either with the Chinese 'suan pan' or the Japanese 'soroban' My fourth graders can easily complete a 99 X 99 multiplication table. For them, learning the simple 9 X 9 multiplication table is so easy.
