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

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.)

Some holiday trigonometric fun! Each worksheet contains a different set of problems. After solving, students use their answers to decode the colour-by-number grid. Every student is responsible for one of the 6 sections of the mosaic. Collaboratively, they create the Christmas tree mosaic! Math involved: ◾Students solve for exact ratio values for a given angles (0, 30, 45, 60, 90 and their related angles in the 4 quadrants) ◾Determine all angle solutions within the specified domain for a given ratio. ◾Coterminal angles are involved as well. Specifically, each worksheet contains 12 problems in the following order: 1) degrees, 1st quadrant only 2) degrees, 1st quadrant only 3) degrees, 1st quadrant only 4) degrees, all 4 quadrants 5) degrees, all 4 quadrants 6) degrees, all 4 quadrants 7) degrees, coterminal 8) degrees, all 4 quadrants 9) degrees, coterminal 10) degrees, all 4 quadrants 11) degrees, coterminal 12) degrees, all 4 quadrants INCLUDED: ◾ Everything comes in both .docx and .pdf format ◾ full set of 6 worksheets ◾ Complete answer key, giving the answers for all worksheets (easy assessment!) ◾ Coloured mosaic picture to guide the assembly of the mosaic ◾ Scrambled answers list at the bottom of each student's worksheet, allowing for self assessment.

Students choose the best method (factorise, quadratic formula, isolating x directly from vertex form...) to solve 12 quadratic equations. This provides some basic practice for students. The picture is a bit of a downer... a sad face. I made this for my students after marking some disappointing tests, recognizing that many needed more practice! The way the task works is: Students solve for the roots of the quadratic and use the "greater" or "lessor" root as indicated to decode the colour-by-number grid. i.e. Blue = lessor root of x^2 + 3x + 2 which is (x+2)(x+1) and has roots -2 and -1, so the "lessor root" would be -2. The student would colour all the squares blue that have -2 inside. The method I had in mind for each question is: 1) simple factorable 2) quadratic formula 3) simple factorable, common factor 4) simple factorable 5) complex factorable 6) quadratic formula 7) simple factorable 8) complex factorable 9) simple factorable 10) quadratic formula 11) vertex form, a value not 1, integer answer 12) vertex form, a value =1, decimal answer This product includes .docx and .pdf version Be sure to check out my Collaborative Math Mosaics for a variety of topics!

Goal: Model a real life problem with a quadratic relation of the form y=a(x-h)²+k , and use this equation to solve problems. Problem: Farmer Bill has 28m of wire fence material to enclose a rectangular garden. He is trying to decide between two possible garden options: Garden A → in the middle of the yard Garden B → against the barn Students will create a table of values, a graph, and determine the vertex form equation for each garden, then answer some questions. The product includes two sheets of grid paper. All the instructions / questions fit nicely on one page; students should show their work on a separate sheet of paper. A sample exemplar is included from a student's work in my own classroom. This makes a nice tidy assignment form MPM2D (Ontario Curriculum)
