Key Concepts & Vocabulary
TermDefinitionExample
MultiplicationThe process of adding a number to itself a certain number of times. It's like a shortcut for repeated addition.3 x 4 is the same as adding 4 three times: 4 + 4 + 4 = 12.
FactorThe numbers that are multiplied together in a multiplication problem.In the problem 5 x 2 = 10, the numbers 5 and 2 are the factors.
ProductThe answer to a multiplication problem.In the problem 5 x 2 = 10, the number 10 is the product.
Times TableA list of the products for a specific number. It helps us learn multiplication facts quickly.The times table for 2 starts with 2x1=2, 2x2=4, 2x3=6, and so on.
Skip CountingCounting by a number that is not 1. It's a great way to practice multiplication.Skip counting by 5s is 5, 10, 15, 20... This matches the answers in the 5 time...

Core Formulas
Commutative Property of Multiplication
a \times b = b \times a
This rule means you can switch the order of the factors and the product will stay the same. If you know 3 x 5 = 15, you also know 5 x 3 = 15!
The 'Add a Zero' Rule for 10
n \times 10 = n0
When you multiply any whole number by 10, you can simply place a zero at the end of that number to get the product.
The Pattern Rule for 5
n \times 5 = ...0 or ...5
The product of any number multiplied by 5 will always end in a 0 or a 5. This helps you check if your answer is reasonable.
