Logic Grid, Garden Harvest With Ratio Clues

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.

Match families, crops and harvest weights using percent and ratio clues like 75 percent of a harvest. The directions on the page read: Each family grew one crop, and each harvest had a different weight. Mark X for no and a circle for yes in every grid square, then fill in the answer table. Last, on each Check line, write the multiplication or division that proves the clue with your weights. An answer key is included.

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.

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.

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.

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.
