MPM2D Culminating Activity - Review Jeopardy

(1)
This task differentiates learning by giving keener students the chance to show their understanding by doing fewer (but more challenging) problems. For grading students work, I usually give "all the points" or "half the points" for a partially correct solution. You could break it into quarters if you need to be more specific :) You can edit the .docx version to suit your specific class needs. This makes a great exam review, even if you don't wish to use it for evaluation purposes! INCLUDED: .docx and .pdf file versions

Colouring by Trigonometry- Right & Oblique, Collaborative 15 Sheet Math Mosaic

(0)
A highly engaging task combining individual accountability with collaborative motivation! Colouring meets Trigonometry in this class-wide math mosaic that will look spectacular hanging up in your classroom :) Each worksheet represents a small section of the big picture! Each worksheet contains 12 problems of the following type: 1) Simple Soh Cah Toa - side 2) Simple Soh Cah Toa - angle 3) Soh Cah Toa - side 4) Soh Cah Toa - angle 5) Soh Cah Toa - side 6) pythagorean theorem 7) Soh Cah Toa - angle 8) cosine law - find side 9) sine law - find side 10) cosine law - find angle 11) sine law - find angle 12) sine law - find side It's simple! 1. Calculate the answers. 2. Colour the squares. 3. Cut out your section. 4. Combine with the class! INCLUDED (.pdf and .docx of everything): --> Full class set of 15 worksheets (all different!) that combine to create the ducky mosaic! --> Full answer keys for all worksheets for easy assessment. Also, a colour-range answer key is provided for at-a-glance assessment. i.e. golden yellow -> [14, 22) --> Teaching Tips page to help you implement this task smoothly CURRICULUM CONNECTION Common Core States Standards: HSG-SRT.C.8, HSG-SRT.D.10, HSG-SRT.D.11 Ontario, Canada: MPM2D, MBF3C, MCR3U, MCF3M Trig 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! 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 stick with the same colouring medium (and encourage quality colouring!). Perhaps a class set of pencil crayons would be a fun math department investment! If your class size doesn’t line up with 15, no worries! You could have some students work pairs (differentiated learning!) or use the answer key to fill in the missing pieces quickly. If your class is bigger than 15, you could hand out duplicate sheets and use the best coloured one, or make two mosaics. Feedback, suggestions, and frontline stories are always welcomed! Thanks for checking this out! ~CalfordMath

Choosing the Correct Trig Tool - "Whose Law is it Anyways?"

(0)
This gameshow style activity provides great practice for students to recognize the criteria necessitating each trigonometry tool (right and oblique). Students are shown a triangle with some sides and angles given, and they must either: 1) Decide what the most appropriate trig tool would be to determine the unknown (side or angle), or conclude that there is not enough information given to solve it. Or, 2) Decide which trig tool could NOT be used to solve the triangle. (This type of problem really builds a deeper understanding) Embedded in the Smart Notebook file is a link to the Kahoot! version that you can play with your class too! (They all log on with their own cellular devices and receive immediate feedback, complete with a leaderboard and bonus points for correct-streaks and quick responses... it's really quite an exciting way to review!) This activity includes the Pythagorean Theorem, Soh Cah Toa (trig ratios), Sine Law, and the Cosine Law. I designed this for my MPM2D (Grade 10 academic math) class, but it would work well with grade 11 College (MCF3M) or even a quick Grade 11 University (MCR3U) review. It does include oblique (non-right) trig, so be warned if you're thinking of using it for grade 10 applied (MFM2P). This gameshow style activity works great with write-and-wipe mini whiteboards, or you could make up little signs with the various trig tools printed for students to hold up. Or better yet, get them to use those cell phone for academic purposes and play the Kahoot! version. Enjoy! ~CalfordMath

Have fun reviewing the key concepts of plane geometry through this fully functional Jeopardy-style PowerPoint! Everything is hyper-linked for easy navigation. This works very well with an interactive whiteboard! Students can play in teams / rows, or work through the game individually in a computer lab. Jeopardy topics are: • Basic Angle Properties (parallel and transversal lines) • Triangles (interior & exterior angle sums, isosceles angles) • Polygons (interior & exterior angle sums, regular polygons) • Prove or Disprove (explain or give a counter example) • Midpoints and Diagonals (quadrilateral diagonal properties and midpoint-joining line segment properties) A preview file is included, giving a complete PDF printout of the slides (questions and answers) The file is modifiable, so you can change up the questions to suit your class.

Equation Clocks - Rich Assessment Task

(0)
In this FUN task, students create an algebra clock where equations are used instead of numbers for each hour. Students can keep their clock, or give it as a gift! INCLUDED: • pdf and Word (.docx) format so you can edit or tweak as you wish. • Lesson Plan • Smart Notebook file to accompany the lesson from beginning to end. (Minds On intro, Examples, rubric template to co-construct criteria with students) • Student Handout with instructions, examples, answer template to complete and hand in. (The student can keep the actual clock... you just need the work!) • Detailed Rubric with criteria for 4 levels • Exemplar Clock Pictures - level 3 and 4 clocks to help students construct success criteria Their knowledge of solving equations, simple and multi-step, through applying opposite operations is solidified and thoroughly tested as they work backwards and forwards to create and check their equations. I found some great $3 clocks at a dollar store! Just make sure you are able to take them apart and reassemble them with a new background face inserted. I hope you enjoy this activity with your grade 8 or 9 class as much as I did with mine! Thanks, CalfordMath Learning Goals: • Apply inverse (or opposite) operations to an equality (equation) to isolate the variable. • Simplify algebraic expressions (distribute, collect like terms, clear fractions by LCD or cross multiplying, etc.) • Understand what it means for a value to be the solution to an equation (i.e. satisfy the equation.) Common Core State Standards: - CCSS.MATH.CONTENT.8.EE.C.7.B Solve linear equations with rational number coefficients, including equations whose solutions require expanding expressions using the distributive property and collecting like terms. - CCSS.MATH.CONTENT.HSA.CED.A.1 Create equations and inequalities in one variable... - CCSS.MATH.CONTENT.HSA.REI.A.1 Explain each step in solving a simple equation as following from the equality of numbers asserted at the previous step, starting from the assumption that the original equation has a solution. Construct a viable argument to justify a solution method. (Ontario, Canada) Grade 9 Academic, MPM1D.NA2 - Manipulate numerical and polynomial expressions, and solve first-degree equations. -NA2.1 simplify numerical expressions involving integers and rational numbers, with and without the use of technology -NA2.3 relate their understanding of inverse operations to squaring and taking the square root, and apply inverse operations to simplify expressions and solve equations -NA2.7 solve first-degree equations, including equations with fractional coefficients, using a variety of tools and strategies.

A triggy web of SohCahToa fun! Students must use sine, cosine, and tangent ratios to determine unknown acute angle measures. Each angle’s letter corresponds to an answer below, helping to solve the riddle, “What did one spider say to another?” 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… Enjoy! ~ CalfordMath CCSS.MATH.CONTENT.HSG.SRT.C.8 Use trigonometric ratios and the Pythagorean Theorem to solve right triangles in applied problems.
