"The easy ones"
Any number x 0 = 0: (4 x 0 = 0, 9 x 0 = 0, 234 x 0 = 0)
Any number x 1 = itself: (2 x 1 = 2, 6 x 1 = 6, 35 x 1 = 35)
Any number x 10, put a zero at the end:
(5 x 10 = 50, 8 x 10 = 80, 24 x 10 = 240)
Other strategies:
- Any number x 2 = double it:
Or just use our song to help you skip count:
"2, 4, 6, 8 who do we appreciate?"
"10, 12, 14 you're the smartest I've ever seen"
"16, 18, 20 I have brains a plenty"
"22, 24 we're done with 2's let's do some more!"
- Any number x 3 n x 3 = (n x 2) + (n x 1)
9 x 3 = (9 x 2) + (9 x 1) = 27
12 x 3 = (12 x 2) + (12 x 1) = 36
Or use our chant (sung to "I don't know but I've been told") to help you skip count:
"3, 6, 9, 12"
"15, 18, 21"
"24, 27"
"30, 33, 36"
- Any number x 4 = "double double" or x 2 twice
8 x 4 = (8 x 2) + (8 x 2) = 32
11 x 4 = (11 x 2) + (11 x 2) = 44
More strategies coming soon...
