In the second number line, it is observed that 1 Whole from the previous number line is further subdivided into 10 equal parts. In the first number line, it is observed that the line is divided into 10 equal parts.Print Worksheet with number lines as given above.Have the student understand that how these numbers are represented on the number line and proceed to the next worksheet of Decimal Number Line. This activity helps the child to understand the concept of what is a decimal. It is important to stress on the placement of the point in decimal numbers. The point when placed in the center becomes notation for multiplication of 1 and 2. Here 1 on the left of the point represents the whole pizza and 0 on the right to the point represents no extra slices of the pizza.ĭecimal is a form of writing whole and fractional part together with a dot or point in between. When there is only one whole pizza and no fractional part along with it, it is expressed as 1.0 pizza. This form of writing whole and fractional part separated by a point in between is decimal form. What is a Decimal:Ī whole pizza and a slice of one-tenth of a pizza are written as 1.1 pizzas. As the kid understood the difference between a part and a whole, introduce decimals as a form of representation to write fractional parts of a whole. The Pizza activity explains the concept of the whole as 1 and the grid activity explains the concept that whole can be 10 also. Conversely, 10 parts of these one-tenths will make a whole.īoth the above activities will make the kid understand decimals from two perspectives. So, this is represented as and called as one-tenth. The shaded region is 1 part out of the whole 10 parts. Explain that the grid is considered as one whole and it is divided into 10 equal parts.Ask the kid how many are shaded and how many are in total.Have the kid shade one square in the grid in the worksheet.So, a whole is complete and a fraction is a part of that complete entity. This is a fractional number because it does not represent the whole but only represents a fragment or a part of the whole. Half = 1 whole pizza divided into 2 equal parts Introduce the concept of half of a whole.Have the student use a Sketch to distribute the pizza among his two friends.
