Calling all π-rates of the Caribbean!
To reach the buried treasure, students must apply the sine, cosine, or tangent ratios, and the Pythagorean Theorem, to calculate all unknown lengths along their path. Right triangle trigonometry just hit the high seas.
INCLUDED:
-> Word (.doc)
-> Colourful handout with instructions
-> Answer key & rubric suggestions
This activity is perfect for Grade 10 Academic or Applied students (ontario curriculum: MPM2D, MFM2P), as it builds the core skill of selecting and using the appropriate trig ratio. This prepares students for the next step of applying this knowledge to real life applications.
This activity is a good compliment to my Angle Tangle Spider Web which focuses on calculating angles.
This is more fun than a straight boring quiz.
There are multiple paths that could be taken, offering some differentiation of ability and student initiative.
Enjoy! ~ CalfordMath

Use trigonometric ratios and the Pythagorean Theorem to solve right triangles in applied problems.

This culminating activity brings all the overall expectations of the grade 10 applied mathematics course (MFM2P) together in an action-packed story line!
Students help the young mathematically-inclined warrior Zachary rescue the kidnapped Princess Eva by applying their knowledge of trigonometry, proportional reasoning, linear relations & systems, quadratic relations, simple trinomial factoring, and 3D measurement.
Will Princess Eva be rescued? Will the Warrior Zachary muster the math power to save the day? Have your students mastered the grade 10 applied mathematics curriculum??
...this task will be the determining factor!
INCLUDED:
.docx and .pdf format of the assignment AND the complete answer key

Highly Engaging! My students volunteered to complete extra sheets! You get two full class set of 28 worksheets that come together to make the giraffe mosaic in both a word-problem format, and in the recently added diagrams-version! PLUS I've added 'small group' versions for 4 or 8 students, making the task very flexible to various class sizes.
Each worksheet represents a small section of the big picture! The end result will look spectacular hanging up in your classroom :)
Students use the basic trig ratios (sin, cos, tan) to solve for sides and angles, then use the answers to colour their worksheets based on the colour key. So much cooler than textbook homework!
It's Simple:
1. Calculate the answers.
2. Colour the squares.
3. Cut out your section.
4. Combine with the class!
INCLUDED (.docx and .pdf of everything):
--> Full class set of 28 worksheets (all different!) that combine to create the Giraffe mosaic.
--> Full sets for both the 4-worksheet and 8-worksheet versions. (More of a traditional colour-by-number style.... look at the preview)
--> A Teaching Tips page to help you implement this task smoothly
-->Worksheets involve a range of right trigonometry problems that involve choosing and/or applying the correct primary trig ratio to solve for an unknown side or angle.
--> Master Answer Key showing both the colour and numeric solution for all worksheet problems for the 28-student version, and the colour key with answer-ranges for the small-group versions.
Teaching Tip: Have students draw a right triangle and label the given information as they read each problem.
The student buy-in factor is HUGE with these worksheets; they all want to see the finished picture come together! High school students love colouring too! This sure beats textbook homework!
Imagine if your students were the ones policing homework completion? "Common Josh! Do your work or we'll have a hole in our picture!"
Leave the picture a secret or show it for motivation… it’s your call.
Encourage students to check their answers by finding them in the randomized list on their worksheet before they colour each square. This will increase the accuracy of the final picture!
All my “Colouring by…” worksheets use standard pencil-crayon colours found in the Crayola 24 pack. For best results, use the exact colour name match (and encourage quality colouring!). Perhaps a class set of pencil crayons would be a fun math department investment!

This task falls right in the middle of Awesome, Fun, and Math! Students each work independently on their own worksheet, solving for the mean, median or mode for a given list of values, yet they work collaboratively to create a whole-class Lego Robin mosaic when the work is all done!
Every worksheet has a unique set of problems, yet follows the same order of problem-type! You can confidently have students work together without cheating. Expect to hear good peer-to-peer math conversation and teaching.
Math Involved:
• Calculate mean value - includes negative values in the list
• Determine the median value - includes cases with both odd and even number of values, (requiring students to average the two middle values). Students must first order the values (good integer practice.)
• Determine the Mode - All sets of values are unimodal (no bimodal, or no mode cases, etc.)
• All answers, and values in the lists, are integers
INCLUDED:
• pdf and docx file versions of the class sets of the 12 and 20- worksheets/colouring grids
• Complete answer keys giving the colour and numeric answer for all problems on every worksheet.
• Students' worksheets have a randomized answer list at the bottom so they can monitor their own understanding.
• A Teaching Tips page, for smooth implementation of this task

INCLUDED:
-> PDF (.pdf)
-> Colourful handout with instructions
-> Answer key / Solution
This activity is a good compliment to my Trig Treasure Map (which focuses on calculating side lengths), building the core skill of selecting and using the appropriate trig ratio. This prepares students for the next step of applying this knowledge to real life applications. It’s perfect for Grade 10 Academic or Applied students (Ontario curriculum: MPM2D, MFM2P)
This is more fun than a straight boring worksheet… it has corny joke!
The triangles are set up to ensure all three trig ratios are required, but in some cases, basic interior angle properties could be employed as well. The final “!”-labelled angle requires some careful thought…

This includes a complete class set of 25 worksheets / colouring pages that combine to create the Spiderman mosaic. Every single worksheet is different, so you can count on hearing great math dialog between your students. And no worries for you… I’ve included the full answer key AND complete SOLUTION KEY. You can make this available to students to self-assess their work (using the task for review or practice), or keep it for your own assessment purposes if you’re markin’ for keeps.
MATH INVOLVED:
◾Students evaluate polynomial functions for inputs in their domains
◾Each problem gives a set of 1 to 3 functions like this:
{h(x)= -5x-3, m(x)= 5x²+22x-1, j(x)= -3x²-5x}
And are asked to evaluate something like this:
h^-1(-5) + m(-3) - j(1)
◾Inverse functions are used in linear cases randomly about 40% of the time
◾Students gain practice with exponent and integer laws (yes senior students still make those mistakes!) and general order of operation skills when simplifying a multi-step expression.
I’d love to hear your feedback and your students’ response to this task.
These tasks ensure individual accountability (since every worksheet is different) while harnessing collaborative motivation (since every worksheet is needed for the mosaic). The end result will look spectacular hanging up in your classroom, and your students will be proud!
INCLUDED:
◾ .pdf and .docx versions of everything
◾ Complete 25-sheet class set of worksheets
◾ Teaching Tips page, for smooth implementation :)

"The tale of a couple of young triangle bachelors, scouting out a party looking to score a few phone numbers..."
Ernie and Stu put their lines to the test when a cute angle is spotted at a hoppin' party. They rely on their knowledge of similarity, proportionality, and trigonometry to prove their compatibility.
Keep it triggy! Check out Trig Treasure Map for a fun right angle trigonometry worksheet, where students solve for missing side lengths using SohCahToa.
This is a FUN little extra to any trigonometry unit! The more math the students understand, the more innuendos and trig references they'll pick up on.
