Solving Quadratic Equations - Solo Colouring Worksheet

(0)
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!

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 CCSS.MATH.CONTENT.HSG.SRT.C.8 Use trigonometric ratios and the Pythagorean Theorem to solve right triangles in applied problems.

The MFM1P 6000, Grade 9 Applied Culminating Activity - Far beyond Pencil and Paper

(0)
A fresh approach to a culminating activity for grade 9 applied math, far from the routine pencil and paper! The “MFM1P 6000” is an interactive computer game which gives students an opportunity to show what they have learned, using models and strategies used in current MFM1P classes, while providing endless opportunity for practice and timely remedial help! Students receive instant automated feedback worded in growth mindset language. This program also provides teachers an extensive summary of students strengths and areas of difficulty. Download the game file, place it in a public handout folder that students can access, and give them 3-4 days to play! Make sure the students have calculators, scrap paper, and perhaps a formula sheet too. Download Tip ◾Your computer will flag the program as a virus. It is just doing it’s job as it should for any unknown executable file! Be assured it is safe. Click “more info” and then “Run Anyway” etc. I know how tough it can be to motivate students to review material from the start of the semester in preparation for EQAO and the final exam. Set them loose in a computer lab for a few days with the MFM1P 6000 and watch the magic happen! Please visit calfordmath.ca/MFM1P6000 for a complete layout of the culminating activity including a complete curriculum connection list, and an up-to-date list of bug fixes and changes. This activity generates every single problem randomly so that every student has a different set of problems and can try as many attempts as necessary to master each topic. The topics span the MFM1P curriculum, and are arranged in difficulty from $100 to $500 score value. To earn 100%, a student must earn $6000 or more, and complete at least two problems from each category. I had tremendous engagement and much EQAO success with my grade 9 applied class last year when I piloted this activity. I have also added and tweaked many things! The game is a Windows Desktop Application designed for a PC. It is not web based, so you will need to copy the game file to a public handout folder where students can open it. I think you and your students will LOVE this! I would love to hear how it goes with your class, and I welcome any suggestions you have! Thanks for checking this out, ~CalfordMath

Quadratic Super Modeller - Really Handy Virtual Algebra Tile Software!

(0)
Teach algebra geometrically! Students will DISCOVER the rules for factorising and completing the square rather than memorize blind algorithms. Algebra tiles can explain the "square" in completing the square, aid students in collecting like terms visually, help with integer operations, and make factorising a visual process! Also, check out Algebra Tile Factris for a game-ified spin on factorizing! Enter ANY quadratic expression in standard, vertex, or factored form and get a digital algebra tile model! The tiles snap in place and don't overlap. This is perfect for teaching students to expand, factor and complete the square. This software requires Windows to run. It is desktop application, created in VB.net (4.5 framework to be specific). I have placed the .exe file in zip folder. It will give you a warning messages, as all .exe files will, when you open the program, but I assure you there is nothing malicious about this software! Simply click "run anyway" or "allow" and enjoy! I created this out of need! The need for better virtual algebra tiles! Students find physical tiles cumbersome to manipulate, and most of the virtual tiles I've found are very finicky to manipulate! This software is more than a virtual algebra tile modeller... it includes step by step instructions, guiding students to the standard, factored, or vertex form! It recognizes when the tiles have been factored (built into a rectangle) or the square has been competed. More than this, it dynamically knows the answer giving either a green checkmark, a red x, or a yellow "half way checkmark" if their answer is not formatted quite right. There is an option to "Just play with the tiles" if you don't wish to be restricted to quadratic expressions. You can add tiles to the panel and it will give the algebraic polynomial tally up top (and even tell you if your tiles are factorable or not). As I continue to tweak and update this program I will update the file here, so you can always download a fresh version, should the file change. You can use this on an interactive whiteboard as a teaching tool, or throw the file in a network drive for students to use individually in a computer lab. Feel free to use this product with your own students, but please do not distribute or post the file openly on the internet or share with colleagues, as this would violate copyright permissions. Send them here! I welcome your feedback and suggestions.
