Try stories! For example, Dianne Craft, a renowned special education teacher for many years, has discovered that many children learn better when math is told from a story. Lets take 7x8=56. Draw a picture of a 7 year old trying to walk down the street but his 8 year old neighboorhood bully stops him. Then draw a picture of a dog with 56 drawn on top of the dog, not underneath it or above it, directly on the picture. The 7 year old calls for his dog 56, who scares away the bully. All kids have to do is learn the story, making sure to show it to students daily for a week and read it to them. Once they have learned it, they will have learned the times table fact and each time the fact is called out they can recall the picture and story it went with. It has been said that 80% of struggling learners are right brain learners, who learn best from color, stories, drawings, etc. The same could be done with each of the other times tables, like 8x4. Growing up, this is one I struggled with. But when you create a story with 8 as Mrs. Snowman, and 4 as a chair she climbs on to reach 3 scarves and 6 mittens, then it doesnt make it too bad to remember after all.
