Here, we slice a circle into two semicircles. Here, we split a rectangle into two smaller rectangles. Tearing an A4 sheet of paper into two halves.
Here, we break apart a circular figure into several sectors. Some examples of decomposing shapes in real-life are: Decomposing Shapes in Real Lifeĭecomposition in Math is evident in day-to-day life. We can break it down to form smaller rectangles, triangles, a combination of squares and triangles, a combination of rectangles and triangles, etc.įigure 4 shows some of the shapes we can get by decomposing a rectangle.
The smaller shapes may resemble the larger shape or may be entirely new shapes.įor example, let us take a rectangle. To decompose shapes means to break shapes into two or more shapes. To decompose 9 into its addends, you will have to think of how you can create this number using smaller numbers. Here, 2 and 1 are addends.Įxample: Consider the number 9. Note: Addend refers to the numbers you add to form the sum. In this method, you separate a number into its different addends. Decomposing a Number Using the Addends Method Here, digit 1 is in the tens place, and digit 9 is in the ones place. The digit 1 is in the tens place, and the digit 4 is in the ones place. In this method, you separate a number into its tens and ones.Įxample: Consider the number 14. Decomposing a Number Using Place Value Method Numbers can be decomposed in two ways: place value method and the addend method. You can even reverse the order of the parts as well, such as: These parts are the decomposed numbers of 6. Think of the different ways in which you may separate 6 into parts. All numbers can be split or broken down.įor example, consider the number 6.
It means to break apart numbers into two or more parts. In other words, you decomposed the square to make two triangles.ĭoes that sound interesting? Come on then, let’s learn more about decomposition. This means that you took a square shape and split it into two triangles. So, now you will both have two triangle-shaped sandwiches. You can split the sandwich into two halves so that each one of you can enjoy it equally. Suppose you have just one sandwich made from two square-shaped bread slices, and you want to share it with your friend. We can decompose numbers as well as geometric shapes. Decompose means to separate or break apart.
