Mysore Zoo Math

Hi  Everyone,

Today we did some math problems using the information from the zoo. The animals we picked have the same classification: they have the same Kingdom, Phylum, Class, Order, Family, Genus and Species. I will be doing a post of Animal Classification soon. Hope you come back to check it out.

This is the math problem my mom made me do using all the wild cats in the zoo. Try it with me. I’ve included the answers too.

The Mysore Zoo has 12 leopards, 3 lions, 4 tigers and 2 jaguars:

1. Draw a data chart (plot against x and y axis) showing the number of animals.

This is a bar-graph that shows the number of wildcats at the Mysore Zoo. I have the number of animals on the y-axis and the animals on the x-axis. It was important to make sure I used a ruler to mark the numbers. It is easy to see that the number of leopards are the highest.

2. Write the fraction representation for each of the animals

First, I have to find the total number of wildcats: 12 leopards + 4 tigers + 3 lions + 2 jaguars = 21 wildcats

  1. There are 12/21 leopards
  2. There are 4/21 tigers
  3. There are 3/21 lions
  4. There are 2/21 jaguars

3. If 2/3 of the leopards were cubs below the age of 1, how many cubs are there?

p_20161123_013029

Total number of leopards = 12 AND ‘of’ means multiplication

2/3 of 12 = 2/3 x 12 = 24/3 = 8 leopard cubs

Hope you try the problems at home. Send me some of your questions that I can work on too.

Doing Math with Family

IMG_20140612_193922

 

Hi everyone, today I will be doing my third lesson called Doing Math with Family. I learnt about Place Value of numbers.
Before learning about Place Value, I have to count the number of DIGITS. Suppose the number is 506, then it is a three-digit number.

Here is an example of counting digits:

Every number has a value called ONES, TENS, HUNDREDS, THOUSANDS, etc.  To know place value of a number, I created the Height Order Test.

PlaceValue2
I use my family members to help me with the place values. The shortest is my bother and he represents the ONES. I am next, so I represent the TENS, My mother is taller than me and she represents the HUNDREDS. Since my dad is the tallest, he will represent THOUSANDS

Just as my dad is the tallest, the THOUSANDS is the largest place value. It is bigger than the HUNDREDS, TENS and ONES
And just as my brother is the smallest, the ONES has the smallest value. Also, there are no values smaller than ONES.

Here’s a picture to show you the place value.

I also found a cool game that helped me understand greater than, less than, and equal to. It’s called Hacker, by PBS Kids. Have fun playing it!

Hope you enjoy the game. If you have more fun facts about Number Sense and Place Values, do share with me in the comments section. Let’s learn together!
