• Week of May 4 - Distance Learning Week 6

    Posted by Mark Redstone on 5/3/2020

    Thanks to everyone who showed up for our Kahoot on Friday! Hayden Musser gets bragging rights as he edged out 10 others to get the Win.


    This week is all about word problems involving quadratics.


    1) Watch the YouTube video for some examples on how to solve these types of problems. The .pdf containing these problems is posted in Google Classroom you'd like to try them before watching!


    2) *This is how you are evaluated this week*. Complete the Google Form posted in GC; to do so successfully, you'll need a pencil, paper and calculator. Some of these are tricky; make sure you answer the question that's asked.


    This essentially ends the state's curriculum for Algebra 1. We covered it all!

    Next week, I'll introduce a topic called "Piecewise Functions". It blends linear equations, inequalities and quadratics, and will serve as an excellent review.

    This week, we review quadratic equations - which method should you choose?



    1) Overview for the week; https://www.youtube.com/watch?v=EG_9YX6JqCM&feature=youtu.be

    2) Watch the following video, where I review all the ways to solve quadratic equations, and choose the quickest method to solve for each.

    3) *** This is how you are assessed this week *** The handout attached to the lesson on Google Classroom is a WhoDunnit, similar to many others you completed in class this year. On a separate piece of notebook paper, work through each problem using a method of your choice. Work neatly! When finished, be sure to indicate the details of the crime. Upload your work to Google classroom - it's just easier for me than emailing. Then, in the private comment section for this assignment, tell me how things are going 😊

    4) Enrichment/Voluntary assignment - Visit student.desmos.com, and enter code BS5788. This activity is not for a grade, but it is an interesting way of seeing how the discriminant effects the roots of a quadratic function. This Desmos activity will serve as an introduction to next week's activity, where we will return to looking at the properties of quadratic functions (intercepts, symmetry, max/min values, domain and range).

    This is an important topic; it is what the last two lessons have built toward. You will see this topic again and again, in Geometry, Algebra 2, and beyond.
    If you have difficulty, be sure to come to a virtual tutorial, Wednesday or Friday at 2:30 pm.

    1) Download the notes on Google Classrooom. Follow through my YouTube videos where the examples have been worked out for you.

    Quadratic Formula - Part 1: https://www.youtube.com/watch?v=xiJhGNzjZo0
    Quadratic Formula - Part 2: https://www.youtube.com/watch?v=Ah7Ha2prwmI&t=5s
    Additional Example, if needed. - https://www.youtube.com/watch?v=Oa_aOUuQp1E

    2) *This is how you are evaluated this week* Complete the Google Form in Google Classroom, be sure to include your name (and school email if prompted).
    Your process work *does not* need to be submitted to me.

    This is my first time using a Google Form like this, so if there are technical difficulties, please let me know! 😁

    This topic continues into next week's lesson, where I will circle back to quadratic functions, and apply these new equation-solving techniques.

  • Distance Learning Week 1

    Posted by Mark Redstone on 3/29/2020

    Distance learning has begun! This is new for all of us, so I am going to take things slowly for the first week or two. Understand that not all students have the same access to technology; they may share devices with siblings, or have limited access to wifi. Until I'm comfortable with how this will work, we will take our time. Only one topic for the first week, to be discussed shortly.

    We had nearly finished the last unit on quadratic functions, with one topic left to go (Quadratic regression). This topic, and many in the unit for that matter, required a graphing calculator. As result, they are not well-suited for distance-learning. I have decided instead to push ahead to the next unit on Quadratic Equations.

    A 90-day trial of a graphing calculator emulator for desktops/Laptops is available at. To my knowledge, there isn't a free (Texas-Instruments) application for tablets or phones. Because of this, lessons will be presented assuming you DO NOT have a graphing calculator.


    Lastly, there will be no STAAR exam this year. Students will receive course credit for completing Algebra-1. Students should simply do their best; please do not stress about your grades!




    1) On the handout posted on Google-Classroom, you'll notice there are notes and examples. These are presented to you in the following YouTube videos:

    2) The last 2 pages of the handout is an assignment for you to complete. Answers will be posted shortly to allow you to check your work. When finished, take a picture or scan of your work (the final two pages only), and send it to me at mark.redstone@houstonisd.org for a 20-point completion grade. If Google Classroom allows you to upload your results directly, that works too! Remember, I'm still learning.

    3) When you feel confident with the topic, just like in class, you will take a brief assessment on OnTrack. Log into the HUB, and complete the 10-question assessment titled "ALG1_QuadEqn_SRoots". This will be valued at 10 points.

    If you need assistance, more information will be coming regarding online tutorials and office hours.

    Students, please join your class using the codes below. I'll be pushing information and assignments out to you shortly. Until then, I look forward to hearing from each of you in the coming days; you're missed.

    Period 1 (Algebra) - 2sey7dk
    Period 3 (Math 8) - 3kmbftm
    Period 4 (Pre-Algebra) - vhz477o
    Period 5 (Pre-Algebra) - wkyswcv
    Period 8 (Algebra) - uty5xh5



    If you can, please consider downloading a 90-day free trial (no licence needed) of a graphing-calculator emulator from Texas Instruments. It's a little clumsy at first, but, it's almost the same interface as we use in class.

    Monday/Tuesday - Students will practice converting between vertex to standard form, and then perform geometric transformations to the parent quadratic function, y=x^2 using Desmos.com


    Wednesday/Thursday - Students will practice transformations, and then be shown how they can use their calculators to find important characteristics of quadratics. Afterward, they may have time to work on their study guide for Friday's test.


    Friday - Unit Test. Polynomial equations, projectile motion, graphing in standard form, vertex form, transformations.

    Monday/Tuesday -The factoring test will be returned today; all students are to make corrections for next class. EVERYONE, unless you scored a 100. The retake is Friday morning.

    After a graded classwork assignment on last week's topic, students will begin to graph quadratics in standard form. They will calculate intercepts, the axis of symmetry, the vertex, and state domain and ranges. The six practice questions are to be completed for next class.


    Wednesday/Thursday - After some more graphing quadratics in standard form, students will begin graphing functions in vertex form. Complete the graded classwork distributed in class (Standard form, cvertex form)


    Friday - A final day of graphing quadratics is the plan! For HW, complete the 8 questions involving equations in vertex form.

    Mock STAAR Exam on Wednesday; Speaking honestly, this is taking place about a month too soon. There will be questions on topics we have not yet covered, so doing your best is all we can ask.


    This week, we will move into quadratic functions. As an introduction, we will spend the majority of the week analyzing scenarios involving projectile motion.


    There are two assignment due this week, the last page of the packet you will be receiving needs to be completed for Friday. It's not easy; I wouldn't leave it too late! Also, corrections to the factoring test are due on Friday. All work is to be shown in pen, on the test. The Retake will be Friday morning, 7:45.

Degrees and Certifications:

Mr. Redstone

I grew up in New Brunswick, on Canada's east coast. I went to the UNB, where I graduated with a degree in Electrical Engineering in 2002. After five years working in the manufacturing sector, I decided that I wanted to return to school to become a teacher.

Best decision ever! Since earning my BEd, I have taught middle and high school math in Houston, Alberta and Maryland.

When it comes to teaching math, I want students to understand not just how to get an answer, but, why their methods work. I facilitate a lot of discussions, and encourage kids to solve a problem "their way", as long as they can justify the validity of their approach to me, and more importantly, their peers.
