Additive & Multiplicative Relationships

How do you identify a multiplicative relationship in a word problem?

• Look for keywords like 'each', 'per', 'times', or 'groups of' that indicate quantities are being multiplied.

• Identify the total quantity and divide it by the number of groups.

• Check if the problem involves addition or subtraction of quantities.

• Look for keywords like 'more than', 'less than', or 'total' that indicate quantities are being added.

How do you identify an additive relationship in a word problem?

• Look for keywords like 'total', 'combined', 'together', or 'more' that indicate quantities are being added.

• Identify the numbers involved and ignore the context of the problem.

• Focus on the final answer without considering the operations used.

• Check for keywords like 'difference', 'less', or 'fewer' that indicate subtraction.

What is the formula for finding the total in a multiplicative relationship?

• Total = Number of groups x Quantity in each group.

• Total = Number of groups + Quantity in each group.

• Total = Number of groups - Quantity in each group.

• Total = Number of groups / Quantity in each group.

If a recipe calls for 2 cups of flour and you want to make 3 batches, how much flour do you need?

• 4 cups of flour

• 5 cups of flour

• 6 cups of flour

• 7 cups of flour

Give an example of a real-life situation that uses an additive relationship.

• If you have 10 dollars and you earn 5 more, you can add them to find out you have 15 dollars.

• If you have 10 apples and you give away 5, you will have 5 apples left.

• If you run 3 miles and then run another 2 miles, you will have run 5 miles in total.

• If you buy 2 shirts for 20 dollars each, you will spend 40 dollars.

What is a key characteristic of additive relationships?

• In additive relationships, the total increases by the sum of the quantities.

• Additive relationships involve multiplying quantities together.

• In additive relationships, the total remains constant regardless of the quantities.

• Additive relationships only apply to negative numbers.

What is the formula for finding the total in an additive relationship?

• Total = Quantity 1 + Quantity 2 + ... + Quantity n.

• Total = Quantity 1 - Quantity 2 + ... + Quantity n.

• Total = Quantity 1 * Quantity 2 * ... * Quantity n.

• Total = (Quantity 1 + Quantity 2) / 2.

If you have 5 pencils and you buy 3 more, how many pencils do you have now?

• 5 pencils

• 6 pencils

• 7 pencils

• 8 pencils

What is a multiplicative relationship?

• A relationship where quantities are added together.

• A relationship where two or more quantities are combined by multiplication.

• A relationship that involves division of quantities.

• A relationship that describes a linear connection between quantities.

Give an example of a real-life situation that uses a multiplicative relationship.

• If you buy 3 packs of gum and each pack has 5 pieces, you can multiply to find out you have 3 x 5 = 15 pieces of gum.

• If you have 10 apples and you eat 2, you have 8 apples left.

• If a car travels 60 miles per hour for 2 hours, it will have traveled 120 miles.

• If you have 4 friends and each friend gives you 2 dollars, you will have 8 dollars.
