This is a good low-key review activity for students, and as an added bonus, is an easy way to get decorations for around your room that the students can help with! There are blank graphs (a tree, hat, mitten, wreath, star, and present) to decorate, and I’ve included 3 sets of 21 cards: systems of linear equations in slope-intercept form, systems of linear equations in standard form, and linear inequalities in slope-intercept form. I cut out the equation cards and randomly hand out 6 to each stud
