The Slope-Intercept Form of a Line Gizmo helps students explore the relationship between a linear equation written in slope-intercept form (y = mx + b) and its graph. By adjusting the slope and y-intercept using interactive controls, students immediately see how each value affects the line's position and steepness on the coordinate plane. The simulation encourages students to make connections between equations, tables, and graphs while developing a deeper understanding of linear functions through hands-on exploration. It is well-suited for middle school algebra, Algebra 1, and introductory high school mathematics classes.

tag(s): charts and graphs (184), inequalities (27)

Here's one that will tie your brain in knots. Some of these logic puzzles will challenge even advanced high school students, but both solutions and discussion are readily available for those who struggle. There are many different puzzle types, and new content seems to appear regularly. Note, however, that the ad banner space occasionally displays content that some might not deem appropriate for school use.

Teachers will find this one a great source for "extra point stumpers."
