Mobile puzzle

Today I created a mobile puzzle. A mobile puzzle is when you have diffrent shapes and you need to figure out how much their worth to create the number at the top

First I thought about what number am I going to put at the top and I choosed 1000.

Next I thought about how to split 1000 with 2 squares and 1 traingle. The trangle is worth 600 and the 2 aquares are worth 200.

So 200 + 200 = 400 then 600 + 400 = 1000 abd thats how I figured it out.

I enjoyed doing this task because it helps me split numbers into 3 parts.
