Usually, children quickly remember the multiplication of small numbers, but they have difficulties with the numbers 6, 7, 8, and 9. To help your child with this, teach them a simple trick.
Turn your palms to your face. Number each finger, starting with the little finger, from 6 to 10. Now, for example, to multiply 7 by 8, connect finger #7 on the left hand with finger #8 on the right. The number of fingers at the bottom, counting along with the connected ones, means tens (we got 5 of them). As for the fingers located at the top, you need to multiply them among themselves — they mean units (in our case, multiply 3 by 2). Answer: 7×8 = 56. In this way, you can quickly multiply by 6, 7, and 8.
#7 = okay. My children will get tattoos on their fingers; the counts from 6 to 10, haha. Or better: all 25 possible results (6..10 * 6..10) on the back-side of the hand.
#10 = false: I have a 110-degrees-hand. My third finger is not 45, it is 30.
