Making of a Wand – For Harry Potter Fans

My twin boys who are really a big fan of Harry Potter Series have been playing with sticks (which they have painted) as pretend wands. It was a perfect opportunity for me as a mother to introduce the electric circuit and help them make a wand that actually glows..So we decided to make a wand out of the materials that we had available at home… The list of the material is given below..(you can actually select anything that is available at home or you can find as a waste material.

Materials Required


Tape (I used surgical tape as it sticks really well..however you can use any tape or glue or Hot Glue as per your convenience)


Dowel or any stick that you can find ( If you can not find a stick you can use the straws and wrap it in the paper)

a paper clip to use as a switch

CR2032 3V Button Cell..

How to make the wand? It’s actually the easiest part once you have all the required parts.

Wand Making – Get the basic structure ready

The LED has a positive and negative the longer one is positive and the short one is negative. I have used the stuff that I had from other project that we had done. So we had a LED holder available . If you don’t have it don’t worry. Just wind your wires around the LED legs and secure the LED on top of the dowel. Tape the wires on the body either with the tape or with the glue gun.

creating basic structure of the wand

Once you have the basic structure ready then check the positive and negative side of the battery and fold and tape one wire as shown in the picture below

Make a Switch

If you don’t have the washer dont worry. you can use a paper clip, aluminium foil or any such small thing that will conduct electricity. Once done fix the battery as shown below

taping in the battery and creating a switch

Fold the wires and give final touch to your wand

Now fold and tape the other wire in such a way that the washer/paper clip/ Aluminium foil does not touch the battery but is positioned in such a way that once you press it, it will touch the battery and complete the circuit. Presto your wand is ready to play with.. you can wrap it with the paper and paint it to give it a real wand like look..

I got the idea from the website a big thank you. What I did was improvisation with the things available at home

How Fraction and Decimals are the same

” What are you learning at School these days?” I recently asked some 4th graders..”Oh we just finished fractions and are now doing Decimals..” They told me..” Well do you know that fractions and decimals are the same thing” I poked a little just to check whether they are being given the conceptual knowledge.. “How can they be the same thingy?” One of the 4th grader piped up..”They are both different things really? Are you guys sure about it? Ok tell me how are these different?” “Welllll..they just are..” ” but how ?” I persisted..” Ok why don’t you tell us how these are the same?” They finally asked.

This was an opportunity I was waiting for.. I asked them ” Do you know that in greek DECA means if we talk about a Decade it means 10 years or if you have heard of the Decathlon in Olympics Decathlon is the combination of 10 events..I am sure you know that our number system is based on 10’s. i.e if we have to write 256 you can write it as 200+50+6?”

” Yes of course” They said. ” Do you know number 10 plays an important part in the numbers which are less than 10?” I said. ” How ?” They asked me immediately.

” Ok , lets take an example…Ussain Bolt holds the world record of 100 meters race which he completed in 9.58 seconds in 2009. here if you see we have 9 whole seconds and then there is a POINT which we call as decimal and then we have 58 after the decimal which is actually part of the whole after the decimal point the first number that comes is 1/10th of a number or we can write it as 0.1. The next number is 1/100th of a number which we can write as 0.01. Lets see what happens when we divide lets say 200 by 10

Place value in Decimals: The above can be explained as given below

200/10 = 20 We can see once divided the digit has moved to 10’s place

20/10 = 2 – here the digit has moved to the ones place

2/10 = 0.2 – The digit has become 2parts of 10’s and has moved to the 1/10th position

0.2/10= 0.02 – The digit has become 2 parts of hundred or 2/100th

0.02/10 =0.002 -The digit has become 2 parts of 1000 or 2/1000th part

“Did you notice that each time we divide the number by 10 the digit shifted one place to the right” I asked..” Yes its like slides almost..”

” So now If we go back to Ussain Bolt we understand that 9.58 is actually 9 full seconds and 58th part of the hundred so we can also write 0.58 as 58/100 or if we have to expand and write the same we can write it as

0.5+0.08 = 0.58. So if you notice the first part is 5 parts of 10 and the second part is 8 parts of 100…

“No one told us like this ..this is really if my teacher gives me 0.25 it will actually me 25 parts of 100, wow.. that means 1/4..”one of them who was faster with calculations said..”Yes it means exactly that.. ”

I was satisfied that conceptually they understood the concept..I made a mental note of teaching them the relation between Ratio, Proportion, Fraction and Percentage next time

Finding Instant Sum and Mean using a calendar

I have been thinking of writing a blog on this for a long time..but then having a set of twin boys and my own activities has somehow come in the way or simply put I have been slightly lazy. However today as a New Year Resolution I have decided to start writing again regularly. Seems like a great achievable idea at this point of time..unless I decide to become lazy again.

Now lets see if things that we use daily can teach us some math..

Math is a fantastic and we can continue to learn it from the everyday things if we are observant enough

Think Differently- Tricks for Addition

While teaching the double digit addition with carryover to my twin boys I was reminded of the method that one of our teachers had taught us in school to make Math fun and to take away the fear of math from our minds. The addition can be quite daunting for children when the numbers are written in a row. Try this method and see how easy it becomes for children to solve the addition problems with bigger numbers

We want to teach children math in such a way that they fall in love with it and should be able to think differently while trying to solve the problems that they find complicated..

Do try this method with kids and let us know the results..Let us also know the areas where the children might need some help or want to make it interesting we will be happy to write about it.  Do leave your comments here or write to us on

We will be taking up another interesting topic from our calendar series next week… Do keep on following us…

Creating Magic Squares

Being a mother is a difficult job and has no job description as well. I love playing math games with my kids and their best friend who loves these small puzzles. As they enjoy it so much I though why not explore the area of magic squares while I am teaching these 7 years old champions addition.

Can you make few magic squares from other combinations of dates from the calendar? Leave your responses here..

Solving the Cross Puzzle using Calendar

In my last post I had shown how we can use the calendar to make number patterns a fun exercise for children. In this article we will go a bit ahead and learn how we can use the calendar to find and solve cross puzzle patterns. I had a lot of fun teaching this to my children hope that others will also find it useful.

Math patterns with Calendar

I was recently watching a youtube video of Dr. Arvind Gupta ( to those who don’t know him..he has done a phenomenal amount of work in the area of science specially for children) and in the video I saw him using the calendar to show how the mathematical patterns can be found in the calendar and how an everyday thing like simple calendar can be made exciting to understand the complicated math problems. I tried to find a few patterns and I am giving few of the things that I found out. I found it very interesting and I hope that you will too.
in my next article I will show how you can make star puzzles, cross puzzles, teach finding the average of the number and make magic squares…

Lets Divide without actually dividing – Few tricks

r nesrAh..How is that possible Mama? My 7 year old son asked me as he read the heading of my new blogpost.. He loves these problems of division and multiplication etc  and knows that as he grows older I will be teaching him all about it( though not yet ready for the competition I have been teaching my sons about multiplication and division through play method, not with the paper or pencil yet.. For example I give one of them 10 sticks and will ask him to distribute it to 5 of his friends so that each one has the equal number of sticks and then I normally ask if they have to take it back and make 10 sticks then to how many friends do they have to go to..they are slowly getting wiser to my tricks though). However coming to the point of what I have written as a title..sounds funny but I assure you its not..

Lets see how we can do it.. Read on to find how we can simplify the division problems

In our next post we will write about more methods of doing the division in easy way..Write to us on if you want us to write on something specific

Multiplication of the 4 digit number- easy way

We had in our earlier post ( had promised that we will be writing about how to expand the same method and do the multiplication of a 4 digit number with a 4 digit number. . Remember we will have 7 patterns in this calculation. Think it as if you are putting numbers in a box and then make the combinations of numbers straight and crisscross. See the slides below to understand how the calculations are to be done

Now here is the challenge to the readers of this post..can you expand this to do multiplication of the 5 or 6 digit number? Do send in your answer to our next post we will start with the Division problems…
