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!
