Rounding Whole Numbers - YourTeacher.com - Math Help


By yourteachermathhelp

In this video students learn to round a number to a given place using the following steps. First find the digit in the rounding place. Next look at the digit to the right of the rounding place. If the digit to the right of the rounding place is less than 5 round down which means that the digit in the rounding place stays the same and all digits to the right of the place become zero. If the digit to the right of the rounding place is 5 or greater round up which means add 1 to the digit in the rounding place and all digits to the right of the rounding place become zero.

This lesson covers basic subtraction in the form of subtracting whole numbers. Students learn to subtract numbers with two or more digits, such as 985 - 47. The first step is to line up the numbers vertically so that the units digits are in the same column. Next, subtract the units digits, the tens digits, and the hundreds digits. When subtracting the units digits, notice that it is not possible to subtract 7 ones from 5 ones, so 1 ten must be borrowed from the tens column, leaving 7 tens and 15 ones. Now, subtracting the units digits, 15 - 7 = 8, subtracting the tens digits, 7 - 4 = 3, and subtracting the hundreds digits, 9 - 0 = 9. So 985 - 47 = 938. Note that the answer to a subtraction problem is called the difference, so the difference of 985 - 47 is 938.

Students learn to round a decimal to a given place using the following steps. First find the digit in the rounding position. Next look at the digit to the right of the rounding position. If the digit to right of the rounding position is greater than or equal to five round up. Then change all digits to the right of the rounding place to zero. Finally we can drop off any zeros to the right of the decimal as long as they are also to the right of the round position. Good review and instruction for all level students.

This lesson covers adding decimals. Students learn to add decimals by first lining up the decimal points, then adding the numbers by column. For example, to add 14.2 + 2.86, first line up the decimal points, then add the digits in the hundredths column, to get 0 + 6, or 6, then add the digits in the tenths column, to get 2 + 8, or 10, so write a 0 in the tenths column and carry the 1 to the units column, then add the digits in units column, to get 1 + 4 + 2, or 7, then add the digits in the tens column, to get 1. So 14.2 + 2.86 = 17.06.

This lesson covers subtracting decimals. Students learn to subtract decimals by first lining up the decimal points, then subtracting the numbers by column. For example, to subtract 9.514 -- 1.6, first line up the decimal points, then subtract the digits the thousandths column, to get 4 - 0, or 4, then subtract the digits in the hundredths column, to get 1 -- 0, or 1, then subtract the digits in units column, by borrowing a 1 from the 9 in the units column (which leaves an 8 in the units column), to get 15 -- 6, or 9, then subtract the digits in the units column, to get 8 -- 1, or 7. So 9.514 -- 1.6 = 7.914.

This lesson covers estimating products. Students learn to estimate a product or quotient by first rounding each number to one non-zero digit. For example, to estimate 8,291 x 27, first round 8,291 down to 8,000, and round 27 up to 30, then multiply 8,000 x 30 to get 240,000.

This lesson covers estimating quotients. Students learn to estimate a product or quotient by first rounding each number to one non-zero digit. For example, to estimate 8,291 x 27, first round 8,291 down to 8,000, and round 27 up to 30, then multiply 8,000 x 30 to get 240,000.

Stem and Leaf Plot


By Turtlediary

A stem and leaf plot shows a large amount of data in a clear way by listing it in order of place value. A stem and leaf plot is generally used when data has multi-digit numbers. In this kind of plot, the ones digit of each number in the data is separated from the other digits. The plot has two columns. The first column, called the “stem”, lists all of the digits in the tens place and beyond, in order. A vertical line divides the stem from the “leaves” (the second column). This second column shows the ones place of each number in the data, also in order. Every number in the leaf column represents a number from the data. Its ones place is in the leaf, and the tens place and beyond are in the stem.

This lesson covers perimeter. Students learn that the perimeter of a figure is the distance around the figure, so the perimeter of a figure can be found by adding the lengths of its sides. Since all four sides of a square are equal in length, the perimeter of a square that has a side with a length of 8 feet is 8 + 8 + 8 + 8, or 32 feet. Since opposite sides of a rectangle are equal in length, the perimeter of a rectangle that is 4.5 meters by 6.2 meters is 4.5 + 4.5 + 6.2 + 6.2, or 21.4 meters.
