3. 2. 1. 4. Change the rounding value or keep it the same ? Find the place value you are rounding to ? Find the value of the number to the right ? Drop the numbers for the left or add zeros ? There are four steps to rounding In order to find the place values you need to know the place values 23456.789 ten thousands ? thousands ? In order to find the place values you need to know the place values hundreds ? 23456.789 tens ? ones ? tenths ? thousandths ? hundredths ? What number is in the tens place 2345.67 What number is in the tenths place 2345.67 What number is in the hundreds place 2345.67 What number is in the hundredths place 2345.67 What number is in the ones place 2345.67 Next we have to figure out the number to the right of where we want to round Next we have to figure out the number to the right 2345.67 of where we want to round If we want to round Next we have to figure out tens the number to the right 2345.67 of where we want to round we look at the number to the right If we want to round to the nearest tens number to the right Next we have to figure out tens the number to the right 2345.67 of where we want to round we look at the number to the right If we want to round to the nearest tens What is the number to the right of the tens place 2345.678 What is the number to the right of the hundreds place 2345.678 What is the number to the right of the tenths place 2345.678 If the number to the right is 5, 6, 7, 8, or 9 then round up If the number to the right is 5, 6, 7, 8, or 9 if it is 0, 1, 2, 3, or 4 then round up then keep it the same Which number would make us round up? 7 or 3 Which number would make us round up? 0 or 5 Let's try a couple Round this number to the nearest thousands Let's try a couple 43472 Find the thousands place Round this number to the nearest thousands Let's try a couple 43472 Find the thousands place Look at the number to the right Round this number to the nearest thousands Let's try a couple 43472 Find the thousands place Look at the number to the right Round this number to the nearest thousands Since that number is 4, then the thousands place Let's try a couple stays the same 43472 Find the thousands place Look at the number to the right Round this number to the nearest thousands Since that number is 4, then the thousands place and everything after the rounding place Let's try a couple stays the same turns to zero 43472 Find the thousands place Look at the number to the right Round this number to the nearest thousands Since that number is 4, then the thousands place and everything after the rounding place Let's try a couple stays the same turns to zero 43000 Find the hundredth place Round this number to the nearest hundredths 12.576 Look at the number to the right Find the hundredth place Since that number is a 6, we will round up Round this number to the nearest hundredths 12.576 Look at the number to the right Find the hundredth place Since that number is a 6, we will round up Round this number to the nearest hundredths 12.586 Look at the number to the right And turn the rest to zeros Find the hundredth place Since that number is a 6, we will round up Round this number to the nearest hundredths 12.586 Look at the number to the right And turn the rest to zeros Find the hundredth place Since that number is a 6, we will round up Round this number to the nearest hundredths 12.580 Look at the number to the right And turn the rest to zeros Find the hundredth place Since that number is a 6, we will round up Round this number to the nearest hundredths but since the zeros are after the decimal we don't write them 12.580 Look at the number to the right And turn the rest to zeros Find the hundredth place Since that number is a 6, we will round up Round this number to the nearest hundredths but since the zeros are after the decimal we don't write them 12.58 What number is in the hundreds place? Round this number to the nearest hundreds 4782 What number is to the right of the hundreds place? Round this number to the nearest hundreds 4782 Will the 7 be rounded up or stay the same? Round this number to the nearest hundreds Rounded Up Stay the same 4782 Will the numbers after 7 become zeros of disappear? Round this number to the nearest hundreds Become zeros Disappear 4782 Will the numbers after 8 become zeros of disappear? Round this number to the nearest hundreds Remain zeros Disappear 4800 Round this number to the nearest tenth What number is in the tenth place? 56.7542 What number is to the right of the tenth place? Round this number to the nearest tenth 56.7542 What is the answer? Round this number to the nearest tenth 56.7542 |
