N for numbers and numerals!

What is a number anyway?

It is a term that is used to count, label, or measure something: zero, one, two, three, and so on, along with negative, irrational numbers, and others.  We can label these numbers when we speak of them, but how do we represent them on paper?  We use numerals! : )

Numerals have been around for a long time and all the different kinds are astounding to me.  What kids need to know is that ten (for example) is a number in written form, but the numeric form is 10.

Short and sweet!

Do you have a favorite number?

M for multiplication! (A to Z challenge)

M for Multiplication--yay!  I love to teach multiplication.  How about you!

Kids like shortcuts, right?!  When you are teaching your students let them know that when you multiply you are really just doing a shortcut.

3x4 is really doing a shortcut for 3 groups of 4 things and instead of adding them all one at a time we can remember the totals of these!  I do have conceptual multiplication flash cards (for sale on TN, TpT) for 1x6 through 1x12.  There are three cards for each multiple!   This is what they look like...

Do your children struggle with multiplication or do they love it?

Another way I like to teach it is by looking at patterns on a 100 chart.

It was a wise fourth grade teacher of mine who let me take a small group of struggling students and do small tutoring sessions during math time.  That is the year I know I wanted to be a teacher.  The moments when my classmates understood how the math patterns worked and how multiplication was really about groups was priceless. : )

L for line (A to Z challenge)

Writing during spring break is a little challenging, but I'm still here : )

L is for Line!

In math we can talk about the term 'line' with a few lessons.
You can teach all about the line and useful applications of it.

 You can ask the kids where they see lines...
Everywhere!
What can be used to make lines?
What do your kids come up with?
Hair, speghetti noodles, a mark on a paper...

See you tomorrow!

J for Japanese Theorem (A to Z challenge)

Well this is embarassing... I must not know my alphabet!  I accidentally skipped J.  I think I was so excited to do my giveaway with my kidsmathteacher as the K that I repressed my knowledge of the alphabet : )

Make sure to enter my giveaway that I posted about yesterday with three great prizes!

For a real stretch for elementary school kids you can show them that there are problems that take multiple steps to solve--theorems.  A problem with all the steps completed make up a theorem.  There is a theorem in geometry called the 'Japanese Theorem' (Thanks Wolfram mathworld for having an alphabetical glossary and explaining things simply).

This theorem states that if you draw the same circle but make triangles in the interior in any manner, then draw incircles to those triangles, the sum of the interior radiuses will always be the same (even if your triangles don't look the same as the others).
Original picture on http://mathworld.wolfram.com
It is pretty neat!  I tried to make my own, but making the incircles is harder than you might think to make sure it barely touches.  I think these look pretty neat and even in kids don't know exactly how to do it, just seeing this makes you curious more about math, right?

'Til Monday!  Have a great weekend!

Giveaway! I for isosceles and K for kidsmathteacher!

Hey everyone!  I'm finally having my blogiversary giveaway!

But first, I am a day behind on the A to Z blogging challenge so I am doubling up today with I and K.

I is for isosceles!  Okay, call me funny but I love triangles.  I thought it was so neat when I found out in junior high that there were different names for them and all about the angles and sides.  Here is how I would have drawn an isosceles triangle before I knew about the cool shortcuts (on the left).  Then on the right is with the equilateral marks (looks so much better!).
A fun triangle activity to do with kids is take any line segment (like a 10" thin strip of paper) and cut it twice to make 3 sections and put the ends together to form a triangle.  See how everyone's triangle is different!  Do the kids know that the interior angles of all of their triangles adds up to 180 degrees?

Now onto K--for Kids Math Teacher!  Okay, I was thinking of doing kite (another geometry term) but then I decided to highlight my blogiversary.  A lot has happened over the last year and I never really thought I would have accomplished so much.  There were days when a lot got done and other days that weren't nearly as productive, but the year went well!

In the past year...

  • I designed and continued to make my blog design a little better (I did it myself--and that was a big learning curve). 
  • I opened up shops on TpT, TN, and BST
  • I started a Pinterest account
  • Made a facebook fan page
  • Learned how to do more graphic design work (I knew a little)
  • Worked on revising several manuscripts and selling one as a printable book.
  • Had some great guest bloggers on here
  • Started a Google + community called Elementary School Teachers
  • I have met great, supportive bloggers and followers just like you!
Wow!  What a year!  I know every blogger progresses at a different pace, I'm slower than some and I know I may be faster than others.  Here are my stats for the past year...
Thanks for making is a great year!  As a thank you I am having a giveaway that will end next Friday at midnight Pacific.

Here are the three prizes!
  1. 6 pack of Lollipics with your custom image!  They will look something like this...
    and they are yummy!
  2. 1 copy of Trouble with Monkeys: A place value story (an original printable book)
  3. 1 set of Animal Cap Kids clipart!

Good luck in the giveaway and thanks for visiting!
