Color by Number #3: Wizard

This is the latest in my series of Excel color-by-number worksheets. This one is aimed at introducing students to some of the ‘magical’ properties of multiplication. Multiplication by 1, 10, 11, 9, and squares are all touched on here. For those who aren’t rabid fans of 80’s Nintendo video games, the character is the Black Mage from the game Final Fantasy, unleashing a QUAKE spell.

Because math is earth-shaking.

My next challenge is to figure out how to let the player choose which spell the Black Mage casts. I sense some heavy IF/THEN in my future . . .

Color by Number #2: Rocket

This is coloring sheet #2 in the Color By Number series, this time using a simple multiplication table. I haven’t figured out yet what the answer to 6 x 6 should do. Any suggestions?

Color by Number #1: Goomba

This is the first in a series of color by number games I’m designing in Microsoft Excel. The worksheet uses conditional formatting to change the fill color of specific cells based on their contents. Then I add a simple formula (=[cell number]) to link the indicated cell to the place where the user types in the answer to the addition question. If they get the answer right, the cells change color, gradually making a picture.

This one is super simple, just four addition questions that yield the image of a Goomba from Super Mario Brothers ™.

Any kind of pixel art is easy to do; you just have to count how many pixels high and wide the image is so you know how many cells in the worksheet you need. Then resize the cells so they are square and go crazy with the conditional formatting. It’s a good idea to go into File — Options — Formulas — Error Checking Rules and uncheck “Formulas inconsistent with other formulas in the region”, otherwise you’ll get unsightly little green triangles in the corners of the cells in your image.
