What does this worksheet teach?
⌄
Fill a three-circle Venn diagram from survey clues, then find a percent and a fraction of 40 students. The directions on the page read: A school surveyed students about three clubs. Use the clues to write the number of students in each region. Then answer the questions, with the fraction in simplest form. 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.
