🧠 Things to Notice
When adding or subtracting decimals, line up the decimal points so digits with the same place value are combined.
When multiplying decimals, estimate first and then use the total number of decimal places in the factors to help place the decimal in the product.
When dividing by a decimal, move the decimal point in both the divisor and dividend the same number of places. Round only when the problem directions require it.
📘 Vocabulary
Decimal: A number written using a decimal point to represent whole-number and fractional place values.
Decimal point: The symbol that separates the whole-number part of a decimal from its fractional part.
Place value: The value of a digit based on its position in a number, such as tenths, hundredths, or thousandths.
Sum: The result of an addition problem.
Difference: The result of a subtraction problem.
Product: The result of a multiplication problem.
Quotient: The result of a division problem.
Dividend: The number being divided in a division problem.
Divisor: The number by which the dividend is divided.
Terminating decimal: A decimal that has a finite number of digits.
Rounding: Replacing a number with a nearby value at a specified place value.
Estimate: A reasonable approximate value used to predict or check an answer.
🔎 Choosing an Operation in a Word Problem
Keywords can provide clues about which operation may be useful, but always consider what is happening in the problem. The same word can sometimes appear in more than one type of situation.
Addition
Possible clues: total, altogether, combined, in all, increased by, more than, sum
Use addition when separate decimal quantities are being joined to find a total.
Subtraction
Possible clues: difference, how much more, how much less, remaining, decreased by, change, left
Use subtraction when finding what remains, comparing two quantities, or determining a change.
Multiplication
Possible clues: each, groups of, times, twice, total cost, area, repeated groups, per item
Use multiplication when equal decimal amounts are repeated or when finding the total for several identical groups.
Division
Possible clues: shared equally, each group, unit price, average, rate, how many groups, per person
Use division when a decimal quantity is separated into equal groups or when finding the amount in one group.
Helpful strategy: Identify what is known, determine what the question asks you to find, choose the operation that represents the relationship, and estimate before calculating.
