Remember: Saving a little each week gets you there. More coins a week means fewer weeks, and a treat only moves the day a little later.

Read and answer

Read the story first, then answer.

Maya saves for a bikeMaya's old bike was so small that her knees bumped the handlebars. The new bike in the shop cost twelve pretend coins, and Maya had none. Grandma said, "Big things take time. Let's make a plan." Maya wrote "Bike, twelve coins" in a notebook and set a jar on her shelf. She decided to save three coins every week. In week two she spent two coins on a treat. By week four the jar still did not have enough. In week five it did, so she bought the bike. The treat only moved the day one week later.

Saving for a bike
13 4 + 4 + 4 = 12. Three weeks of four coins is 12 coins.
26 coins a week More coins a week means fewer weeks. 6 coins a week takes 2 weeks.
3False 3 + 3 + 3 = 9, not 12. It takes a fourth week: 3 + 3 + 3 + 3 = 12.
410 coins 4 weeks of 3 coins is 12, and 12 − 2 = 10. That is not enough for a 12 coin bike yet.
513 After week four the jar held 10, and 10 + 3 = 13. That is more than the 12 the bike costs.
6True The treat used 2 coins, so the bike came a week later, in week five, and treats are okay.
71-A, 2-B, 3-C, 4-D 1 × 12 = 12, 2 × 6 = 12, 3 × 4 = 12 and 6 × 2 = 12. More coins a week means fewer weeks.
83, 2, 5, 1, 4 She wanted the bike, made a plan, saved week after week, and bought it in week five.
93 coins a week, 4 coins a week, 6 coins a week 3 coins a week takes 4 weeks, 4 coins takes 3 and 6 coins takes 2. 1 coin takes 12 weeks and 2 coins takes 6.
10The treat only moves the bike a week later. She still gets it A treat uses coins, so the bike comes later, but saving a little each week still gets her there.
112 2 coins a week takes 6 weeks and 3 coins takes 4 weeks. 6 − 4 = 2. The extra coins cut less and less.
