Word problems with percents (tips, sales, scores) need you to read what's happening, take a percent of a number, and sometimes add or subtract. Warm up friendly percents and clean adding/subtracting first.
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 put two amounts together to make a bigger total.
Example: 40 + 8 = 48.
Level 1 To take one amount away from another.
Example: 20 − 5 = 15.
Level 1 One of two equal parts of something.
Example: Half of 60 is 30 (60 ÷ 2).
Level 1 To make a number 10 times smaller.
Example: 20 ÷ 10 = 2.
