To compare deals or scale up, you first find the unit rate (the cost or amount for one) by dividing, then multiply to get more. Warm up dividing-to-find-one and your times facts.
These are words you'll need to already know to follow this lesson — not the new words the lesson teaches. Review each one, its meaning, and the example so the new lesson makes sense from the start.
Level 1 To split a total into equal groups to find the amount for one.
Example: $8 ÷ 4 = $2 for one pen.
Level 1 To add the same number many times to scale up.
Example: 2 × 6 = 12 dollars for 6 pens.
Level 1 A word that means "for each one."
Example: $2 per pen means $2 for each one pen.
Level 1 To look at two numbers to see which is bigger or smaller.
Example: $2 is less than $3, so it is cheaper.
