Logic Grid, Planter Volumes
Written by Adi Ackerman, Head Teacher
"Logic Grid, Planter Volumes" is written for 8th Grade (Ages 13-14), and it covers Common Core 8.G.C.9. A 7th grader who is already steady on math puzzles can use it too, and an older student can use it as a short review.
8th grade math worksheet: find cylinder, cone and hemisphere planter volumes in terms of pi, then match gardeners and plants. Answer key included. Part of our logic puzzles collection. Aligned to Common Core standards.
How do I use this worksheet?
Use a math logic grid to review a unit or a reasoning puzzle as a break between units. Model how to mark one clue before students start.
What students will practice
- Students will find volumes of cylinders, a cone and a hemisphere in terms of π.
- Students will compare planter volumes to apply each clue.
- Students will mark a logic grid that pairs gardeners, planters and plants.

What does this worksheet teach?
⌄
Find cylinder, cone and hemisphere planter volumes in terms of pi, then match gardeners and plants. A hemisphere is half of a sphere, so its volume is half of 4 3 πr³. The directions on the page read: Find each planter's volume in terms of π. Then use the clues to mark the grid: X where a pairing cannot be true and a dot where it must be true. An answer key is included.
Can I use this logic puzzles worksheet for homeschool or classroom?
⌄
Yes, both. We made it for 8th grade math puzzles, and it works the same at home or at school. At home, a student can work through it alone and then go over it with you, which shows quickly what is solid and what needs another look. In class it works as independent practice, homework or a warm-up, and you can print one copy or a full set.
How do you solve a logic grid puzzle?
⌄
Read each clue and mark X where a pairing cannot be true and a dot or circle where it must be. When a row has only one open square, it must be the match. Keep going until every square is marked.
What is a nonogram?
⌄
A nonogram is a grid puzzle where the numbers beside each row and column give the lengths of shaded runs. Shading only the squares the clues prove reveals a hidden picture, such as the hot air balloon in the 12 by 12 puzzle.
How do math clues fit into a logic grid?
⌄
Students first solve a problem, such as finding four slopes or four planter volumes, and then use those answers to apply the clues. Logic Grid, Kite Strings and Right Triangles uses the Pythagorean theorem this way.
