Explain to children that multiplication is repeated addition; this could help a number of children understand the multiplication process. For example, teach a child that 3 multiplied by 2 is three added together twice, or that it is 3 plus 3.
Tell students that any number multiplied by zero is always zero; no exceptions.
Explain that any number multiplied by one is always itself. For example, 1 multiplied by 8 is 8 and 1 multiplied by 156 is 156; always.
Teach that any number multiplied by two is always that number doubled. For example, 2 multiplied by 7 is 14, which is the double of 7.
Teach children to count by fives. Learning to county by fives makes it simple for children to multiply anything by a five because it can be done easily and on their fingers.
Show kids to multiply by nine using their fingers by having students hold up both hands with their fingers splayed. Explain that each finger, starting from the left and working toward the right, represents the numbers one through 10. Have each student curl their left pinky downward to represent one multiplied by nine, which is nine as represented by the remaining nine fingers still splayed. Each finger to the left of the curled finger represents the "10"s: 10, 20, 30, 40, 50 and so on. Have the children once again splay all ten fingers and then curl down the pointer finger on their left hands. The pointer finger is finger "4" which means that the multiplication problem is 4 times 9. Because there are three fingers splayed to the left of the curled finger you know that the total of 4 times 9 is something in the "30s". Count the fingers to the right of the curled finger; there are six remaining. This tells the student that the answer to 4 times 9 is 36.
Tell kids that anything multiplied by 10 is that number with an additional zero at the end. For example, 2 times 10 is 20, 10 times 10 is 100.
