factor – a number that is multiplied by another number to find a product
product – the answer to a multiplication problem
Distributive Property of Multiplication – the property that states that multiplying a sum by a number that is the same as multiplying each added by the number and them adding the products
ex: 5x13 = (5x10) + (5x3)
partial product – a method of multiplying in which the ones, tens, hundreds, and so on are multiplied separately and then the products are added together
expanded form – a way to write numbers by showing the value of each digit
Associative Property of Multiplication – the property that states that you can group factors in different ways and get the same product
ex: (6x10)x10 = 6x(10x10)
estimate – a number close to an exact amount
round – to replace a number with another number that tells about how many or how much
Use the four operations with whole numbers to solve problems
CC.4.OA.1 Interpret a multiplication equation as a comparison, e.g., interpret 35 = 5x7 as a statement that 35 is 5 times as many as 7 and 7 times as many as 5. Represent verbal statements of multiplicative comparisons as multiplication equations.
Use the four operation with whole numbers to solve problems
CC.4.OA.2 Multiply or divide to solve word problems involving multiplicative comparison, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem, distinguishing multiplicative comparison from additive comparison.
Use the four operations with whole numbers to solve problems
CC.4.OA.3 Solve multistep word problems posed with whole numbers and having whole-number answers using the four operations, including problems in which remainders must be interpreted. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.
Use place value understanding and properties of operations to perform multi-digit arithmetic
CC.4.NBT.5 Multiply a whole number up to four digits by a one-digit whole number, and multiply two two-digit numbers, using strategies based on place value and the properties of operations. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.
