How I Actually Use the Speed Calculation Cheetah Coloring Sheets
I've been running elementary science centers for over a decade, and the color-by-number speed calculation worksheets are one of those resources that sound clever on paper but require actual setup work. The concept is straightforward enough: students solve speed problems (distance divided by time), then color a cheetah illustration according to the answer key. The cheetah part is basically decoration. The math is where things get interesting. You can download a printable version of the answer key from the TPT listing or directly from the teacher resource page. I always grab the full 6-page packet rather than just the key because the student worksheet has some formatting quirks that aren't obvious until you've actually printed it. The answer key itself is a single page showing the correct color-for-number mapping alongside the computed answers. It matches each problem number to a specific color code, and the color legend maps numbers to the cheetah regions. The file is a PDF, roughly 200 KB. It prints cleanly on standard 8.5 by 11 paper. I recommend using a fresh ink cartridge because the small color areas get muddy if your printer is running low on cyan or magenta. I learned that the hard way with a batch of 30 copies.
What This Worksheet Actually Tests
The problems cover basic speed calculations where students rearrange the formula s equals d over t. Most questions give distance and time and ask for speed. A few reverse it and ask for distance when speed and time are known. The cheetah theme means the numbers tend to stay in the realm of realistic animal speeds — roughly 60 to 70 kilometers per hour for top speed, with distances in the range of 100 to 500 meters and times in the 2 to 8 second window. Nothing exotic. What most teachers miss is that this worksheet isn't great at testing unit conversion. A few problems mix meters and seconds with kilometers and hours, which trips up about a third of my students on the first pass. I catch this early and do a five-minute warm-up on the board before handing out the sheets. Without that, the grading curve flattens in a weird way where kids who can do the math still get answers wrong because they didn't convert.
How to Run It in Class
Set it up as a two-part station. First, students work the problems independently. They write their answers in the margin or on a separate scratch sheet. Second, they consult the answer key, verify their work, and then color. The coloring takes about ten to twelve minutes for a typical class. The math takes another fifteen to twenty depending on how many need unit conversion support. I usually let them use calculators for the division step. The point of this sheet is conceptual understanding of the relationship between distance, time, and speed, not long division practice. If I ban calculators, the activity drags out to nearly forty minutes and the kids lose focus before they finish coloring. Fifteen to twenty minutes is the sweet spot for engagement and completion. One thing I do differently from the default flow: I have students check their answers against the key before they start coloring. If I let them color immediately, there's a feedback loop problem where a wrong answer locks them into a wrong color and nobody notices until the end. That creates confusion during review and some kids get frustrated coloring something that looks wrong compared to the reference image. Checking first eliminates that entirely.

Color By Number Speed Calculation Cheetah Answer Key
The answer key uses a simple color legend. The number one corresponds to yellow for the cheetah's main body. Number two is black for the spots. Number three is light brown for the underbelly shading. Number four is white for the tail tip. Number five is orange for the accent areas near the legs. The exact mapping varies slightly between versions, so always compare your worksheet's instructions to the key you downloaded rather than assuming the colors carry over from a previous edition. Print the key double-sided on the back of the student worksheet if your printer supports it. This cuts down on paper waste and stops kids from losing the key halfway through. I've seen that happen at least once per class period when the key is on a separate sheet.
Edge Cases and Where It Breaks Down
The worksheet falls apart if your students haven't recently covered the speed formula. It assumes they already know how to isolate t or d from s equals d over t. I ran this with a group that had only been introduced to the concept the week before and hadn't practiced rearrangement yet. Half the class couldn't get past problem three and ended up coloring randomly just to finish. For those groups, I assign a different activity and use this sheet only after a targeted mini-lesson on algebraic rearrangement. Another issue: the time values in some problems produce repeating decimals. Problem seven asks for the speed of a cheetah that runs 450 meters in 14 seconds. The answer is approximately 32.14 meters per second, and the worksheet rounds to one decimal place. A few students round down to 32 and match it to the wrong color bucket because the key uses 32.1 as the threshold. I tell them to look at the first decimal digit and round accordingly. It's a minor thing but it causes unnecessary errors. The biggest limitation of this resource is that it doesn't differentiate well. High-performing students finish the math in eight minutes and then color for fifteen. Lower-performing students spend twenty minutes on the math and still rush the coloring. There's no extension built into the packet. If you need differentiation, I add a second problem set where students create their own speed scenarios and calculate the results, then swap with a partner to color. That adds about ten minutes and keeps the fast finishers occupied without requiring me to pull a separate worksheet.
Download and Usage Notes
The file is freely available through standard teacher resource platforms. It's licensed for classroom use only, which means you can print it for your students but shouldn't post it publicly or sell it. The publisher allows personal classroom use and sharing within a school building. If you're a homeschool parent, the license covers your household. I keep a backup copy on a cloud drive because the original download link sometimes goes stale after platform updates. Worth mentioning since you don't want to be stuck halfway through a lesson because a URL changed. The total class time for this activity, including setup and cleanup, runs about thirty to thirty-five minutes. If you're short on time, skip the independent math phase and do the problems as a guided group activity instead. Students still get the coloring reward and you maintain control over pacing. The learning outcome is comparable, just less individual practice.
Overall, it's a decent resource for reinforcing the speed formula in a low-stakes format. It's not a substitute for actual problem-solving practice, and it doesn't handle units gracefully. But for a Friday aftertest activity or a sub plan that needs minimal prep, it gets the job done. I've used it at least six times across two school years and it hasn't failed me yet, aside from the usual printer ink issues and the occasional kid who colors outside the lines anyway.
