Using number lines is a great way to introduce adding and
subtracting numbers. It’s a fantastic visual that students can have in front of
them and physically move a marker to add more or take some away. Number lines
will be extremely helpful when you get into adding and subtracting negative
numbers as well.
A number line is a straight line with equally separated
dashes. Each dash represents a whole number in this situation. Numbers go from
zero to… “Infinity and beyond” as Buzz Lightyear would say, in both the
positive and negative directions. The arrows show us that it continues on.
Now, I stumbled upon a really neat and FREE application or
“App” for elementary kids on Ipads. Ipads are becoming more popular in schools.
As teachers we should take full advantage of that opportunity and become
familiar with the technology and find some helpful resources for our classroom.
I found an app called “Little Monkey Apps”. (You can download for free on Ipad
or Iphone) I’ve attached the youtube tutorial video below so you can get the
full feel of this application. Basically, it’s a kid friendly number line that
uses frogs as moveable markers. There is a variety of things you could do with
this app: Adding, subtracting, and counting by odds or evens are just a few
things. It’s really fun and I think that kids would love it. It makes cute
little frog noises too when you move them. Thankfully for us teachers there is also a
tutorial for teachers to read the full advantages of this Ipad/Iphone
application.
