Tetradyron - A special 3D shape

Explore the world of shapes




We all have taught our children about shapes. Square,rectangle and a pointy triangle, then there comes 3D shapes; cube, cone and sphere.

But have we thought of combining these shapes to make more shapes or designs?

I'm gonna tell you very craft way of combining a "simple shape" and make it into a "3D shape".

Let's get those two point in bold. Simple shape is triangle and the 3D shape is a tetrahedron.

 


Hmm, pretty clear to me, you tell me how helpful it was?

Making the tetrahedron is so fun that we had it as an activity in our game night for the homeschooling kids.
Lots of tetrahedrons
First name that comes in the mind is, its a "pyramid".

And its true!

The tetrahedron is one kind of pyramid, with a flat triangle base and triangular faces connecting to a common point.

 A tetrahedron is also known as a "triangular pyramid"





A combination of tetrahedron is called a Sierpinski triangle

Do you want to conduct such activity at home or for a geometry class?

Lets make lemonade

Math in the kitchen. This is the right title for this blog, as we teach measuring units and fraction in this lemonade making activity, so let's get started.



Lemonade ingredients

The first step was to write a basic recipe for the lemonade and write an ingredients list on a board where students can refer to while making the juice.

All the required tools should be gathered on a table, which includes:

  • Measuring Spoons - To measure dry ingredients and lemon juice
  • Measuring Cup - To measure water 
  • Lemons
  • Water
  • Ice cubes
  • Sugar
  • salt
  • Empty glasses 
Students have explained the use of every tool

At their turn, every student measured (with spoons marked either tablespoon or teaspoon) and put the dry ingredients in the empty glass, added lemon juice, and water at the end with the help of a measuring cup.


A lemonade stand in an open space, the best activity for summers

Learning outcomes:


  1. The two standards of measuring with the spoon were discussed - Tablespoon (Tbsp) and Teaspoon (tsp).
  2. Fractions were discussed as kids put 1/2 Tbsp lemon juice or any other ingredient infraction, they were also asked to double or triple the recipe. 
  3. Kids also observed "dissolving of sugar and salt".
In the end, everyone enjoyed a fresh glass of chilled lemonade and of course made at least two more adjusting recipes to their taste.

What do you think about our activity, did you have a lemonade stand? Tell us about it in the comment section. Saima Faisal signing off.

Tesselate the shapes

Patterns and designs are everywhere. Natural and man made designs have been around for hundreds of years but we'll never know who put together the first tessellation. 

Kids have a spacial interest in patterns; this is how they learn and make sense of thing around them.

Patterns also involve shapes hence I decided it should be introduced to children as its actually a complete study in math. Which study? This one.

"Special pattern in which shapes or pattern cover a surface without any gap is called a tessellation (tes-sel-la-tion)".

So I gave a lot of solid, colored shapes to kids at my center to let them make patterns freely.

A hexagons will tessellate and make interesting patterns


Rocket :)

And soon there was a tessellation in front of me, I immediately gathered kids around and made them take notice of the design in front of them.


A six years old working with design having hexagon in center


Its surprising kids took hexagon as center figure as it has more sides to connect


This pattern seems to be favorite of all

Square and diamond




Triangles, squares and hexagons are the only regular shapes which tessellate by themselves.

And that's a wrap!
Our next project will be making quilts and tiles using tessellation and my kids are more than ready to take part, stay tuned, like and comment below about this write up!

Up close and personal with math anxiety




She was sweating.” Let’s jump in twos on this number line. Start with two and keep on adding two.” I told Zehra, who was looking at me with wondering eyes. “Keep your two fingers open in front of you if you need to add.” I stretched her right hand in front of her. She kept pulling her shirt down from the side.” It’s a game” I assured her (maybe she was thinking I am taking some sort of a test).


“Ok! Let’s start, two….” There was no answer from her.”


“Add two in two, what’s two plus two?”


“Five”, she finally said.


“See these two beads”, I pointed at the beads on the table, we had just practiced making groups of two.


“It's four”, she looked at them and counted while moving her head at every count.

“There you go, you got it. Now let’s continue”

“Two, Four …..”



No answer. Hmm, ok, let’s color these shapes. See some shapes here”, I took a sheet of paper with a star, a circle, a rectangle, a pentagon, and a square. “Which one is square, can you guess, can you color a square.”

 She nodded and happily picked a crayon. 


“Why can’t she tell two plus two is four”, Mona, 9 yo girl whispered loud enough and Zehra raised her eyes a bit.


“I couldn’t add when I was seven, it happens, maybe it happened with you too when you were seven but now you can now add quickly and so will she when she’s nine.” I couldn’t think of a simpler reply.

We were having a math review session with two girls, seven and nine. They were doing their work according to their class level. Zehra was joining class two in a month and Mona class four. Whenever I asked a math sum with an “audience” present, Mona’s anxiety symptoms were visible, when she was alone; she was the most confident, happy, and attentive child.


“She doesn’t hate math”.


 “What? She doesn’t?” 


“No!”


 Zehra’s mother was surprised, she had earlier told me her daughter simply hates math and loved only reading. And I told her good readers are also good at math. Math is a collection of words just like a language; if they can make sense of one language so can they make sense of math, which is also a language of symbols having some meaning.


“But she doesn’t want to do the math.”  


“So don’t do math, don’t make it a burden, a dreaded task, she actually enjoys math if done alone.”


“How can someone do math alone?”


And that’s the main point I want to emphasize in this article. Why not? Part of the problem in children who hate math is that they are afraid of making mistakes and the current setup of our classrooms seems not to accept it or at least their classmates don’t.

Group work in a math class


In a math class kids who prefer to work independently and alone (introverts) are facing constant pressure from their peers who are racing to reach a solution and deliver it out loud, and by doing so making the introverts friends nervous and lose their concentration.


The solution seems simple.


Combine group and independent task in a math classroom so both categories of students get their chance of participating and actually enjoying math in class.
