Dance, Factors Dance: Animated Factorization Diagrams #mathchat

Kelly Tenkely1 Comment on Dance, Factors Dance: Animated Factorization Diagrams #mathchat3315 views

What it is:  Dance, Factors Dance is a fantastic site to visualize factorization diagrams.  The first “tango” is inspired by the digital clock, with a separate diagram for each of the hours, minutes and seconds.  The Factor Conga is a “promenade of primes, composites, and their constituents, arranged with an aesthetically-tuned variation of Yorgey’s rules, one per second.”  I love the way these math factorization dances help students visualize numbers and Prime numbers.  Brilliant!

How to integrate Dance, Factors Dance into the classroom: Dance, Factor Dance is a stupendous way for students to visualize and think about numbers.  I Love the way that the prime numbers are depicted…so easy to see why it is a prime number!  Ask your students to explore this site and identify the patterns they notice in the dance of numbers.  What happens when a number is prime?  When a number is odd?  Even?

Dance, Factors Dance is a fun way to learn more about numbers, it is also a wonderful inspiration for finding the art in math.  How can students use the site as inspiration to create their own math dance?  Could they use stop motion animation and manipulatives to do something similar?  What patterns in math do they notice?  How can they use color and design to help them better understand math?

This site is a great one to explore as a class, as a center on classroom computers, or individually on student devices.  Students can pause the dance, rewind, and fast forward as they explore.

Tips: Be sure to watch (or fast forward) to the three digit numbers…this is where things get really impressive!  As a side note, I learned something today from a fellow teacher.  When looking at numbers in grid form, you know if a number is prime if it can only make one rectangle.  This understanding would have been helpful in math class! Better late than never 🙂

Splat Square

Kelly Tenkely1 Comment on Splat Square13488 views

What it is:  Splat Square is one of those very simple websites that you will end up using weekly in your math classroom.  Splat Square is a 100 grid that starts out blank.  There are different ‘splat’ colors on the right side of the screen.  Choose a color and then click on the square, ‘splat’, the number is revealed with a splatter of colored paint.  The interactive grid is wonderful for several applications in the math classroom.

 

How to integrate Splat Square into the classroom: Splat Square is perfect for use with an interactive whiteboard.  Teach students to count by 2, 5, 10, etc. by ‘splatting’ those spaces as you count aloud as a class.  Teach students the difference between odd and even numbers by color coding the 100 grid, prime numbers, skip counting, and ordinal counting can also be practiced with Splat Square.  This is a great grid to use with the whole class with the students interacting with the grid on an interactive whiteboard.  It can be used as a interactive math help center or individually in a lab setting.  I like using the grid for whole class math games, I call out what rule I want the teams to follow and they can take turns at the board.  

 

Tips:  Share this one with parents, it can be a big help for your visual learners during math homework.

What it is: ict Numeracy Games are created by educator James Barrett.  These flash games are excellent for primary and beginning secondary elementary students to practice math.  You will find game themes for number facts, counting, bridging through ten, time, shape and measures, greater than and less than, multiplication and rounding, money (this is UK money), addition, subtraction, odd and even, place values, doubles, and equivalence.  Each math or numeracy theme has several games to play for practice.  Each is interactive and has instructions for integrating the game into the classroom.  All great ideas!

 

How to integrate ict Numeracy Games into the classroom: The ict Numeracy Games are perfect for use with an interactive whiteboard or projector and whole class instruction.  Several of the games are also great practice for students working on individual computers.  The games are all very engaging.  They teach and provide practice for basic math skills.  This is a great stop when you are looking for an interactive activity to practice a math concept.  The descriptions next to the game are very helpful and you are bound to find new ideas for integrating technology into your classroom.  

 

Tips: There are advertisements on this site but they are unobtrusive, your students probably won’t even notice.  The games are high quality enough that this shouldn’t be a deterrent.
