It would be helpful to me if people would share ideas for developing automatic recall of specific number combinations. I find that children will often encounter a few combinations that are difficult for them to memorize and these combinations vary from child to child. I have used the 5678 trick for 7X8, 321 for 7X3 and using two 7's to form a 14 (the top of the first 7 is removed to make the middle horizontal stroke of the four) for 2X7. I am currently "rescue tutoring" a perfectly intelligent 15 year old whose addition skills are poorly developed, so even though 7X2 is a "two", the "trick" helped her. She understands multiplication fine and can figure out the answers. It's the development of immediate recall that has, for some number combinations, been hard for her. I especially would love to have "tricks" for 4x7,6X7,3X6,3X8, 6X8 and 4X8, but ideas for other combinations would be welcome as well. For this particular student, word associations with numbers has not worked at all.
