“Put Together” and “Take Apart” Problems Previously, children solved “add to” and “take from” problems within 100. Children will now solve “put together” and “take apart” problems that include an unknown variable. Children will use manipulatives, drawings, and counting on and back.

It means to break apart numbers into two or more parts. All numbers can be split or broken down. For example, consider the number 6. Think of the different ways in which you may separate 6 into parts. 1. 3 and 3 2. 2 and 4 3. 1 and 5 4. 0 and 6 These parts are the decomposed numbers of 6. You can even reverse the order of the parts as well, such as...
To decompose shapes means to break shapes into two or more shapes. The smaller shapes may resemble the larger shape or may be entirely new shapes. For example, let us take a rectangle. We can break it into several shapes. We can break it down to form smaller rectangles, triangles, a combination of squares and triangles, a combination of rectangles ...
Decomposition in Math is evident in day-to-day life. Some examples of decomposing shapes in real-life are: 1. Cutting a pizza into slices. Here, we break apart a circular figure into several sectors. 2. Tearing an A4 sheet of paper into two halves. Here, we split a rectangle into two smaller rectangles. 3. Cutting a slice of lemon in half. Here, we...
There are no fixed rules to follow when it comes to decomposing shapes. You have to think about breaking up a shape to form smaller standard geometric shapes. Consider figure 5 below, which depicts a rocket. When you think of it as a rocket, you will visualize a single figure. But when you think of it in terms of shapes, you will identify various g...
Decomposition in Math is an essential skill for understanding higher concepts of math and geometry. Decomposing numbers helps to develop number sense and relationships between digits. Decomposing shapes sets the stage for understanding the concepts of perimeter, area, and volume.
Example 1: Decompose the number 10. Solution: For decomposing 10, we separate it into its addends. 10 = 1 + 9 10 = 2 + 8 10 = 3 + 7 10 = 4 + 6 10 = 5 + 5 Example 2: Decompose the number 12. Solution: in the number 12, the digit 1 is in the tens place, and the digit 2 is in the ones place. So, decomposing 12 into tens and ones will be equal to: 12 =...
Standard and Expanded Form. Some people call the two different forms "Standard" and "Expanded": 349. 300 + 40 + 9. Standard Form. Expanded Form. Example: Put 925 into Expanded Form. 925 = 900 + 20 + 5.
Put together/take apart problems involve two groups being put together or two groups being taken apart or separated. These problems do not involve change. A part-whole mat is a good model for this type of situation.

Worksheets, solutions, and videos to help Grade 1 students learn how to solve put together/take apart with addend unknown word problems and relate counting on to the take from ten strategy. Common Core Standards: 1.OA.1, 1.OA.3, 1.OA.4, 1.OA.6, 1.OA.5, 1.OA.7. 1.OA.8. Lesson 22 Concept Development.
Apr 3, 2018 · Breaking apart an addend is a mental math strategy for addition. Some students may find this method more efficient than left-to-right addition. This strategy involves breaking up one addend in an equation into more manageable parts.
