Braingenie - Math and Science

This free website offers a way to learn and practice elementary and high school mathematics as well as Biology, Chemistry and Physics.  To take a look click here.

NRICH

NRICH has a plethora of lesson plans and activities for math teachers as well as posters with challenge activities.  To see the website click here.

Photomath

From their website, "Photomath is a mobile application described as a "camera calculator", which utilizes a phone's camera to recognize mathematical patterns and to display the solution directly onscreen. It is available for free on Google Android and iOS"

I have utilized this app on my phone and it works well with typed questions and even on my hand written questions.  Not only will it show you a solution but will show you the steps used to get the solution algebraically and graphically.  This works from basic arithmetic through trigonometry and Calculus.  To see the webpage click here.  The downloads can be found for iOS by clicking here  and for Android by clicking here. 

Purpose Games

If you want to review for a test this might be a place to look.  If you need to practice naming parts of the skeleton or practice your algebra try this site.  To see the site click here.  To see an algebra game click here.  To see a label a skeleton game click here.  To see a plant cell game click here.  Make sure to use the search box to look for previously made games or make your own.

Magic Gopher

I saw that Richard Byrne posted about this website.  The Magic Gopher is site that asks you to pick a two digit number and then subtract the sum of the two digits from the original number.  The gopher then asks you to look up the symbol associated with the result and voila the little one  guesses your answer.  The key is that a two digit number say "ab" is mathematical really 10a+b and if you subtract the sum of the original digits you are doing 10a + b - (a + b) = 9a.  If you notice all multiples of 9 on his list have the same symbol.  This could be used as an introductory to algebra by asking your students how the gopher does it or if you are teaching the distributive property.  To see the website click here.

Algebra and Calendars

"Why do we need Algebra?"  A common refrain from students.  This problem might work for some of your junior students.  Cynthia Lanius from Rice University posted this over a decade ago about using Algebra and Calendars.    She starts by asking students to pick for days that form a square and adding the dates together.  The students tell her the sum and she tells them the 4 days.  She uses some basic algebra in her head to do this.  To see the site click here.  If you want to see the algebraic solution to the problem click here.

Is Algebra Necessary?

The article by Patrick Hohner entitled "N Ways To Apply Algebra With The New York Times" is a rebuttal to Andrew Hacker's New York Times essay "Is Algebra Necessary?"  If you work with formulas in your Math, Science or Technology class you might want to look at this article that has several examples that you might use in your class.   To see this article click here.

Algebra 1

This is from mathispowr4u and it is a nice video library of Algebra 1 material.    The material covers straight lines and solving systems of  linear equations.  Take a look by clicking here.

Algebra and Barbie

Barbie jumps off the roof but tries not to hit the ground.  In the following article students used the line of best fit to help them with this fun activity in their Algebra class.  To see the article click here.

Concert TIckets and Algebra

From Mr. Miller.  A typical text book math question is A ticket agency sells tickets to a professional basketball game.  The agency charges $32.50 for each ticket, a convenience charge of $3.30 for each ticket, and a processing fee of $5.90 for the entire order.  The total charge for an order is $220.70.  How many tickets were purchased?

You could do a similar question with your class by photoshopping out a screenshot from TicketMaster after going through and pretending to order concert or sporting or tickets to the theatre as shown below.

Happy Thanksgiving

Notice Mr. Miller photoshopped or painted out the number of tickets.  Now your students can do set up the algebraic equations and then solve.  Note that setting up the equations is a key part of how they can be marked.  Then you can reveal the answer.
