This is a quick Multiplication trick kit that can help students remember patterns and quick "know-hows" of multiplication.
I used this in 3rd grade and my students loved it and benefited from it! They are color coded so that students can use them at home, at school by themselves, or with their friends! They love showing all the "tricks" they've learned.
-2's trick - add the number to itself.
-5's trick - the last digit is 0,5,0,5
-multiply by 6's trick - ends in same digit
-9's trick - last digit decreases (9,8,7,6,5...)
-9's trick - using hands/fingers to help
-9's trick- adding digits together to make 9
-10's trick - put a zero!
-11 trick - repeat digit
