Logic Grid With Integer Clues
Written by Adi Ackerman, Head Teacher
"Logic Grid With Integer Clues" is written for 7th Grade (Ages 12-13). A 6th grader who is already steady on math puzzles can use it too, and an older student can use it as a short review.
7th grade math worksheet: use signed difference clues to match four neighbors with garden plot sizes and tomato counts. Answer key included. Part of our logic puzzles collection.
How do I use this worksheet?
Start with a logic grid such as Logic Grid, Four Fair Booth Shifts, then move to puzzles with number clues. Have students mark X and dots in pencil and check each clue once the table is full.
What students will practice
- Students will read signed differences such as +10 square feet and negative 7 tomatoes to compare amounts.
- Students will mark X and dot squares in a logic grid until each neighbor has one plot size and one tomato count.
- Students will record the solved pairings in a table to show every clue is satisfied.

What does this worksheet teach?
⌄
Use signed difference clues to match four neighbors with garden plot sizes and tomato counts. A signed difference shows which amount is larger: if A minus B is −3, then A is 3 less than B. The directions on the page read: Read the clues. In the grid, mark X where a pairing cannot be true and a dot where it must be true. Then write each person's plot size and tomato count in the table. An answer key is included.
Can I use this logic puzzles worksheet for homeschool or classroom?
⌄
Yes, both. We made it for 7th 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 every clue and mark X in the grid where a pairing cannot be true. Mark a dot or circle where it must be true. Repeat until each person has one match, then copy the matches into the table.
What math appears in these logic puzzles?
⌄
The clues use integers, percents of $400, ratios of ages, fractions of an hour and fractions of page counts. One sheet uses a Venn diagram of survey counts and another uses equations for balanced scales.
What is a nonogram?
⌄
A nonogram is a picture puzzle with number clues beside each row and above each column. The numbers give the length of each group of shaded squares in order. The 10 by 10 sheet includes a finished small example to study first.
Do the logic puzzle sheets have answer keys?
⌄
Yes. All 16 sheets have an answer key that shows the solved grid and table.
