Formula that always equals 5
Friday a student, Miss P, showed our 2nd period class how to take a number and always get 5 as the answer. By 5th period, we were testing it with any number we could think of.
Here is the formula: number + (number +1) +9 divided by 2 - original number.
STEPS:
Choose a number.
Add number you chose to the next number when counting.
Add 9 to that sum.
Divide that sum by 2.
Subtract the original number from that quotient.
You should have a difference of 5!!!!
Example: 8+9=17+9=26/2=13-8=5
I challenge you to tell me why this always equals 5. (Hint.. look at just the numbers in the formula)

Properties of Solid Shapes and Volume
This week we began discuss the various properties of solid shapes and how to find the volume of these shapes.
Properties of Solid Shapes
We began by reviewing what we knew about solid (3D) shapes. For examples: Faces, Edges, and Vertices.
Faces - The flat side of a solid shape
Edges - Where two faces meet
Vertices -Where three or more faces meet
We also talked about what a polyhedron is, a solid shapes whose faces are all polygons. From here we learned about mathematician Leonhard Euler (pronounced "Oil-er"). Euler discovered the relationship between faces, edges, and vertices.
Euler's Theorem states that (F + V) - 2 = E. We tested this on several polyhedrons.
Volume of Solid Shapes
At the end of the week, we began discussing volume of a solid shape.
We identified two different ways to find volume.
- If the shape were irregular (not an identifiable polyhedron) we would just count the cubic units.
- If the shape were regular polyhedrons we can use the formula length x width x height.
To engage the students in class we use "Whole Brain Teaching" often. If you are interested read more about it here: Whole Brain Teaching
Many times, when using WBT in class, I have the students use their friends, "Smarty" and "Dufus". These guys are their hands that talks to one another. Smarty is just as his name implies, he knows how to do the skill and is a very nice, polite teacher. Dufus is not as smart and asks several questions. Dufus needs Smarty's help a lot.
Ok, I tell you guys all of this to explain the following video. I told the students I found "Smarty" and "Dufus" on youtube.com Here they are ready to teach you how to find volume. Enjoy!

March word problem
"Owl Love to See "hoo" Can Solve These Word Problems!
This month's word problems was 100% student created. The students decided theme, the banner phrase, and what colors they wanted to use. I think they did great!!!
We focused on comparing and ordering fractions. As you look at the examples, you will notice they used different strategies to compare and order these fractions. Some of the students looked for the LCM (lowest common multiple) to create a common denominator and an equivalent fraction. Others drew a fraction chart and shaded the fractional amounts to visually compare and order the fractions in their word problems.

How technology is making my job easier
This is awesome! Earlier this year all the teachers in my building were given ipads. (Thank you PTA)
Recently after taking notes in our math journals, I had the students do some independent practice on the concept. Instead of hauling 100 math journals home, I had the students take a picture of their work. Now, I only had to take one thing home to see if the students grasped the concept.
I LOVE technology!!!!

March Math Calendar
Wow! It has been a couple weeks since a post, but it has definitely been a busy couple of weeks. Now that I am back in the groove below is this month's math calendar. Enjoy!
Please notice:
1 - Xtramath still an ongoing assignment
2 - Math homework is moving to Wednesday nights
3 - NO - Xtramath during the week of Spring Break
