Two-Step Challenge: The Star Tower Star Party

Professor Luna Moon is throwing a Star Party at the Star Tower! These are challenge problems: each one needs two steps, a multiplying step and one more step.

Remember: Read the whole story, then plan: first multiply the equal groups, then add, take away or share what the story says. 6 rows of 25 cushions and 20 more: 6 × 25 = 150, then 150 + 20 = 170 cushions.

Magic trick: After the first step, stop and ask: “Is that what the question asked?” If not, take the second step!
