- Lesson Plan →Objectives, pacing and practice, built from this lesson's brief.
- Guided Notes →One page your students fill in and keep.
- Exit Ticket →Three items at the end of class. No student accounts.
- Re-teach →After an exit ticket: who missed what, and what to do tomorrow.
- Homework →Assign practice; it grades itself.
"Use percentages to solve problems in a variety of contexts:
• including, but not limited to, discounts, interest, taxes, and tips.
• including those that involve percent increases and decreases for many different quantities."
"Understand and use the relationship between percent change and growth factor (5% and 1.05, for example); include percentages greater than or equal to 100%."
"In a group, 40% of the items are red. Of all the red items in the group, 30% also have stripes. What percentage of the items in the group are red and have stripes?"

What you'll learn
- Solve a problem with more than one percent step by writing each step as a multiplication applied to the quantity that percent refers to
- Find the net effect of successive percent changes by multiplying their growth factors
- Find an original value from the value after a percent change by dividing by the growth factor
- Express a percent of a percent as a percent of the whole
- Decide what each of two percents is a percent of, and combine them accordingly: add percents of the same whole, multiply for a successive change or a percent of a percent, and go through the amounts for separate groups
