X 2 - DOUBLES - Students relate these to the doubles learned in addition. (Example: 7 X 2 = 14 is the same and 7 + 7 = 14)
X 4 - DOUBLE THE DOUBLE - Students are asked to double the double to find the answer. (Example 7 X 4 = 28, Students think 7 X 2 = 14 and 14 + 14 = 28, so 7 X 4 = 28.
X 5 - CLOCK FIVES - When looking at the clock, students think of the 5 minute intervals represented by the numerals. (Example 6 X 5 = 30. Students think, when the minute hand is on the 6 it is 30 minutes after the hour.)
X 3 - COUNT BY 3 - Students memorize counting by 3's and use this knowledge to memorize the facts. (Example 7 X 3 = 21. Students count by 3's 7 times. 3,6,9,12,15,18,21)
X 9 - NINE HAND JIVE - Students hold both hands in front of them and number the fingers mentally 1 - 10 starting with the left pinky. They bend over the finger that corresponds with the number times nine. The number of fingers to the left of the bent over finger is the number in the tens place of the answer. The number of fingers to the right of the bent over finger is the number in the ones place. Example:
There are only a few facts left for the students to memorize after using the above strategies. They are 6X6=36, 6X7=42, 6X8=48, 7X7=49, 7X8=56, 8X8=64.
