In this super secret number puzzle, students work with writing equations of lines. Students need to know about writing the equation of a line through a given point, but with a little twist.
Students are given three numbers and a point. Students must arrange the numbers correctly so they make a linear equation that goes through the given point.
After the students figure out the correct placement of the numbers, they write the numbers in the appropriate blank at the bottom of the page. They should then add and subtract as indicated to obtain the super secret number.
After a bit of time, I tell them what the super secret number should be. If their super secret number matches mine, they probably did their problems correctly. A fun way to practice an important skill!
