# Discover Decimals with Cuemath

Our education system tells children how to manipulate and calculate decimals but they are never taught what decimals really are. One day, we asked a group of grade 5 students whether 0.19 is greater than 0.2 or not. To our surprise, most of them said 0.19 is greater and the reason they gave was that 0.19 has 19 while 0.2 has 2.

When children learn decimals with Cuemath, they learn with the help of learning aids, children build a conceptual understanding to answer questions like these correctly.

Let’s take a 10*10 grid and think of it as 1 unit. Let’s call it 1 flat. Then let’s take a 10*1 column of this grid and call it 1 rod. Note that 1 rod has a value of 1/10 which we can write as 0.1. Now, take a 1*1 grid such that 1 block equals 1/100. We can write it as 0.01.

With these modelling tools it becomes easier for children to visualise decimals. They can represent a collection of flats, rods and blocks using decimal numbers. For example, one flat plus two rods is equal to 1.2. Similarly, they can represent 0.43 as the sum of 4 rods and 3 blocks.

Now let’s get back to our question of finding whether 0.19 is greater than 0.2 or not with the help these Base Ten Blocks. Now it is crystal clear that 0.2 is great than 0.19. Way simple than mugging formulae. Isn’t it?

Isn’t this a great way to learn decimals with Cuemath?

Your child will never forget a beautiful piece of mathematical reasoning like this. This academic session, let your child discover the new way of learning with Cuemath!

Hello

I’m an endodontist i.e a dentist with a postgraduate in the field of endodontics. I’m pregnant that’s why not able to work. Would like to work with cuemath. Do let me know if there is any room for me.

Excellent method of explanation .This helps the students to visualize the numbers.

Excellent way to teach math. I am p.g.in MBA in IT.my child is 6 months old only that’s why I m not to work outside. Is there any chance for me to teach from home..

The colours used here helps children in visualisation it is necessary to make class attractive . But I wonder how much time a child is needed to do a sum . While in ordinary lecture classes teachers used to finish an entire exercise .
