Color by Number

ND State Standards
7.NO.NS.1 Describe the absolute value of a number as its distance from zero on a number line.

Learners should be introduced to the notation of absolute value at this level.

Find a Coloring Page:

• Start off by finding a free coloring page by using Google to search for "free coloring pages". I would suggest pictures that have large coloring spaces and avoid small detailed mandala type adult coloring pages as they can be intricate and not have the space you need.

• Download or copy this page into your preferred document editor, I suggest Powerpoint or Google Slides! You may need to resize your power point/google slide to match the 8.5x11 size piece of paper. Please reach out if you need help doing this.

Prepare Your Coloring Page:

• Once your coloring page is ready, decide on at least 15 distinct sections within the picture that will be assigned different colors.

Create Numerical Expressions:

• For each section of the coloring page, create a unique question that involves describing the absolute value of a number and its distance from zero on a number line. 

• Write out a total of at least 15 expressions, ensuring that each expression evaluates to a different number.

Create a Key:

• Fully work out each question, showing all the steps needed to reach the final answer.

• Create a key that matches each evaluated expression with a specific color. For instance:

  • 10 = Blue

  • 25 = Green

  • 15 = Red

• Make sure to clearly show all your work in the key, not just the final answers.

Color Code Your Page:

• Assign each section of your coloring page a numerical expression from your list. You can do this in powerpoint or google slides by inserting a text box.

• Include the evaluated number (answer) from your key next to the expression in each section so the learner coloring can match the number to the corresponding color.

Final Touches:

• Review your coloring page and key to ensure everything is correct.

• If desired, add a title to your coloring page and some instructions for the learner coloring it.

Example - this particular example uses color by number but solving for x, so while we are not using solving for x with this lesson; it does give you an idea of what your project should look like at the end.
