Summary of Activity : Students work in groups of 4 to determine the value of each of 3 shapes, using 4 clue cards equations. When they have the solution, they raise their hands and show me. If they are correct By the Shapes Answersthey mark off that clue set number at the bottom of the recording sheet to keep track of which sets they have completed and I give them another set. The best part of this activity is the conversation that happens within the groups.
It helps to do the Teacher demo so they have an idea of what they are supposed to do. I told them to use all the clues at the same time to figure out the value of each shape.
Solving Equations Song — even my high school boys will clap and sing along to this one. Gallery Walk Variables on Both Sides — I post each sheet of 3 problems around the room and give each student an answer sheet. Students work with a partner and rotate among the 10 sheets of problems, choosing one problem from each sheet to complete.
Crumple and Shoot also known as Trashketball — powerpoint of equations with variables on both sides of the equals sign. Students work in teams of 4, each studnet has a number from Every student does every problem on white board. I use a random number generator to call a number from That student holds up their board — if the answer is correct, their team gets one point and they have the opportunity to get extra points by shooting a piece of scrap paper into our recycle box.
Students are encouraged to work together with their team to complete the problems since they never know who will be called to show the answer.
Linear Equations Song
Great communication encourager. Pass the Probem — Equations — in groups of 4, students pass one problem around the group, each student doing one step of the problem. Directions are on the first page of this document. Students work in groups 4, each student completes one of the problems on the placemat. They find the sum of their solutions and write the sum in the center of the placemat. I only have to check one number to know if they have all solved their problems correctly.
After using this activity, I found that it was better for me to write the equations onto the placemats so that the problems were oriented so that the students could see the problems easily without the problem being upside down.
I also used markers so it was more colorful. Hot Seat Solving Equations — powerpoint of equations. Students have to determine what the first step would be in solving the given equations includes literal equations. Students are in 4 teams. Study Guide — prior to taking the unit assessment, we prepare a study guide.
I also played a game of Risk using equations. I put the problems on the board and showed them one problem at a time. They did the work on the back of the recording sheet and wrote the answer only on the front along with how many points they wanted to risk on that answer.
I revealed the answer, we discussed it, and they calculated their points working in pairs to keep them honest. I love this math community! August 18, by lzlomek 35 Comments. My favorite unit to teach is Linear Functions. The students get the answer sheet and rotate through the problems in any order to write and interpret the linear equations.
The link includes the answer sheet and the 2 pages that have all 20 problems on them that I made for students who were absent. This takes most of my students about 60 minutes to complete. They do use the TI graphing calculator eventually, but I want them to really understand where the equation comes from.The quadratic formula is a formula used to solve quadratic equations. It is the solution to the general quadratic equation. Quadratics are polynomials whose highest power term has a degree of 2.
Each of these is referred to as a root. Geometrically, these roots represent the points at which a parabola crosses the x-axis. Thus, the quadratic formula can be used to determine the zeros of any parabola, as well as give the axis of symmetry of the parabola. If a quadratic is missing either the bx or c term, then set b or c equal to 0.
If the quadratic does not contain the ax 2 term, you cannot use the quadratic formula because the denominator of the quadratic formula will equal 0. In that case, you can use algebra to find the zeros. The quadratic formula mainly involves plugging numbers into the equation, but there are a few things you need to know. The part of the formula within the radical is called the discriminant:. This means that when the discriminant is positive, the quadratic will have two solutions - one where you add the square root of the discriminant, and one where you subtract it.
Although the quadratic equation may at first seem daunting to remember, repeated use can help.
If you know the tune to "Pop goes the weasel," you can also sing the quadratic equation to its tune to help you remember the quadratic equation. The song goes:. See also quadratic functiondiscriminant.Related Topics: More Math Mnemonics. If you need to find Tcover up T in the triangle and you get.

It’s In The Bag! Equations Project
In the last lesson we talked about the frequency ratios of common intervals. The standard convention is that interval ratios are greater than 1 and less than 2. A ratio of is an octave, so it makes sense that all the other intervals are defined to be smaller than an octave.
Following the overtone series we get these basic ratios: is our starting tone, is an octave above that, is a fifth above the octave, is the second octave and is a third in the second octave. We want to express the fifth and third as frequencies within the first octave — therefore the ratio has to be greater than our starting tone and less than the octave.
Therefore, we can divide the frequency ratio by the number of octaves necessary to bring it into the first octave range. For example, the ratio is a perfect fifth in the second octave. Therefore we only need to bring it down by one octave to have the ratio be between 1 and 2. So if a fifth in the second octave is and the second octave is then would be a fifth in the first octave.
We can define this as the following:. This equation shows how a prime ratio can be transposed into a single octave. From this equation is follows that:. Therefore we can frame the precise definition for our interval ratio as follows: a basic interval is an interval whose ratio is p divided by two the n-th power, where p is prime and n is chosen so that 2 to the n-th power is the greatest power of two less than p.
The first three basic intervals from this definition are consonant and very important in the foundation of our musical definitions: the octave, perfect fifth and major third,and respectively.
These variables will make it easier for use to define complex equations later on. Therefore we can define the following variables, a, v and t:. Now that we have those three variables defined, we can prove a method to determine the composition of any other interval as a combination of those three. To give an example we can now express intervals as functions of a, v, and t and determine the ratios quickly — such as the sum of a perfect fifth v and a major third t :.
This is great in terms of raw theory — but how does it come into play with how we tune our instruments or understand music? It has to do with the value of measurement applied to the intervals and logarithms.Search this site. Inkscape Tutorials. Cybersecurity Curriculum. Dance Party HOC. Applied Digital Skills.
