This is a smartboard file where students need to find matches for domain and range of graphs written in interval notation. This game is similar to the children's game "Memory." Student move 2 slides at a time looking for matches. This activity is done as a class and can be used after teaching domain and rage from graphs. I have used this where I have made teams (sometimes one half of the class versus the other) and had them alternate picking "cards." Just drag the box and reveal what is underneath. Kids love this activity and it is a great way to practice a skill while keeping kids entertained.
