Have them study their multiplication facts at home EVERY night. Cool Ways to Study 1. Play “Around the World” with your family. 2. Use flash cards and have a sibling quiz them. 3. Challenge your child to a multiplication face off. See how many facts they can write down in one minute. Have them practice identifying what a number is divisible by everywhere they see numbers (on road, in the store, on television, newspaper, etc…) o This will enhance their knowledge of factors and helps with long division. Help your child with their number sense. o What is an Even number? o What is an Odd number? o Even numbers can be divided into groups of 2 with NO remainder. All even numbers have a 0, 2, 4, 6 or 8 in the ones place. Odd number cannot be divided into groups of 2 with NO remainder; there is always an “odd man” out. What is a prime number? Prime numbers only have 2 numbers (factors) you can multiple in the world to get that number. Ex. 2 = 1 x 2, 3 = 1 x 3; 23 =1 x 23 o What is a composite number? Composite numbers have more than 2 numbers (factors) you can multiple in the world to get that number. Ex. 4 = 1x 4 & 2 x 2 (3 factors); 15 = 1 x 15 & 3 x 5 (4 factors) o What is a perfect square number? The product (answer to a multiplication problem) of a number times itself. 1x1=1 4 x 4 = 16 7 x 7 = 49 10 x 10 = 100 2x2=4 5 x 5 = 25 8 x 8 = 64 11 x 11 = 121 3x3=9 6 x 6 = 36 9 x 9 = 81 12 x 12 = 144 Make certain your child can factor a number to only its primes (PRIME FACTORIZATION). o This skill will promise your child success with finding the greatest common factor (GCF), least common multiple (LCM) and simplifying fractions. Hint: Memorize the Important Prime Numbers: 2, 3, 5, 7, 11, 13, 17, 19 How to do Prime Factorization 1. Place the number on top. 2. Draw two tree branches. 3. Write down two factors (Never 1) that equal that number when multiplied together. 4. Break down each number under the branch until you get to the primes. 5. Circle all of the prime numbers. 6. Write an equation by setting your number equal to the product of prime numbers. Hint: To write the prime factorization using exponents, just count how many you have of each prime and place a small number at the top. Ask your child to tell you one thing they learned in Math today? o Review the class notes nightly with your child.
