Back to Math Problems (Ages 7 to 9)
Walter loves video games and learning musical instruments. This week, he spent time each day on one of his favorite indoor activities: learning guitar, learning violin, learning piano, playing Roblox, and playing Geometry Dash. Walter did a different activity each day from Monday to Friday.
Using the following clues, determine which activity Walter did each day:
1. Walter played Roblox either on Tuesday or Thursday.
2. Walter learned piano the day before he played Geometry Dash.
3. On Wednesday, Walter did not learn violin.
4. Walter played Geometry Dash two days after he learned guitar.
Let’s analyze the clues step by step:
1. From clue 2, we know Walter learned piano the day before he played Geometry Dash.
2. From clue 4, we know Walter played Geometry Dash two days after he learned guitar.
3. Combining these clues, we have two possibilities:
a) Guitar on Monday, Piano on Wednesday, Geometry Dash on Thursday
b) Guitar on Tuesday, Piano on Thursday, Geometry Dash on Friday
4. From clue 1, we know Roblox was played on either Tuesday or Thursday.
5. From clue 3, we know Walter did not learn violin on Wednesday.
Considering these facts, option b) doesn’t work because it leaves no day for Roblox.
Therefore, the correct order is:
– Monday: Guitar
– Tuesday: Roblox
– Wednesday: Piano
– Thursday: Geometry Dash
– Friday: Violin
This order satisfies all the given clues:
1. Roblox is played on Tuesday.
2. Piano (Wednesday) is the day before Geometry Dash (Thursday).
3. Violin is not learned on Wednesday.
4. Geometry Dash (Thursday) is played two days after learning guitar (Monday).
