Algebra students need plenty of opportunities to explore the various representations of linear functions and see how they are interconnected. This is a lesson I use when my students are first beginning to explore functions. Although I use snap cubes, you could make patterns with any materials you have. This hands-on lesson introduces students to the relationship between growing patterns, function tables, sets of ordered pairs (relations), and graphs. It also introduces the concept of slope and challenges students to formulate equations based on their findings. There is a guided lesson for the class to do together, 2 levels of practice activities that could be done in pairs or small groups, and an individual assignment you could use for homework. You will notice that Pattern A on the "Try It On Your Own" page is easier than Pattern B. Use pattern B for your students who catch on quickly and need something a little more challenging.
