Rather than students simply doing math problems and coloring a designated area a specific color, students actually get to create the picture to be colored and choose what type/s of problems will be given in each box. Students could make the picture be a flower, a soccer ball, a pattern, etc. They could include problem types as simple as basic addition and subtraction or include fraction operations such as adding fractions or finding equivalent fractions. Answers could be in a range. For example, anything that equals a number between 0 and 10 could be colored purple, anything that equals a number between 1/2 and 3/4 could be colored blue, etc.
Students will need two copies. First, they will create their picture. Then, they must put their problem types in making sure it matches the key. A teacher could copy their un-colored work and allow other students to complete the math coloring picture.
