Divide students into groups of three, four or six and give each group 50 cotton balls (or jelly beans, or pompoms, or marshmallows - whatever small object is accessible in your classroom).ДЄsk students to divide the objects up so each member of the group has an equal number, then watch and wait.Д®ventually, theyвЂ™ll understand they canвЂ™t divide it evenly and there will always be some objects left over.

Instead of jumping right into an equation with remainders, start with another object lesson. Have your students practise the step above until theyвЂ™re comfortable with the basic format. Teach students that when theyвЂ™re asking how many times 2 can go into 4, theyвЂ™re really asking how many times 2 goes into 40. Use these simple equations to reinforce place value. Then, repeat the step with the second digit in the dividend. Once they come up with the correct answer, put 2 above 4.

This might be a tricky concept for them, so use the idea of sharing: If you want to share 4 objects between 2 people, how many objects does each person get? 658, we go from 2 tens to 2 ones.) It appears, though, as if the decimal point has shifted one place left, or, with the whole number 26580, that a 0 has been taken off.ДЄs we move down the list - as we push the digits to the left through theДecimal point - each number has been multiplied by 10.ДЄnd so we can easily multiply or divide by a power of 10 because of our systemД®ach place belongs to the next power of 10.ДЄt this point, please 'turn' the page and do some Problems.Ask students how many times 2 fits into 4. When we divide a whole number by a power of 10, theДЄnswer will have as many decimal digits are there are 0's.ДЄgain, as in Lesson 2, consider this array:ДЄs we move up the list - as we push the digits one place right - theВ number has been divided by 10 because each place to the right is worth 10 times less. Starting from the right of 265, separate one decimal digit. Starting from the right of the whole number, separate as How do we divide a whole number by a power of There are no 0's to chop off We will see that we must place a decimal point to Now in Lesson 2 we saw that when a whole number ends in 0's, weД«ut when a whole number does not end in 0's - as 265 - then

These example illustrate that, whenever we multiply or divideД«y a power of 10, the digits do not change We simply move the decimal pointДЇinally, we must see how to divide a whole number by a Move the decimal point left as many places as How do we divide a decimal by a power of 10? Since money has two decimal digits, we added on a 0. Since 50 pounds are ten times 5 pounds, they will cost ten Pounds of sugar cost $2.79, how much will 50 pounds cost?ДЄnswer. The answer is a whole number, 732, which we write without a decimal However, since all the digits fall to the left of the decimal point, Move the decimal point right as many placesДЄs there are 0's in the power. How do we multiply a decimal by a power of 10? The student should let go of that written method immediately. But it is not skillful, and it does not take advantage of positional numeration. Traditional multiplication would eventually give the right answer (we hope). How do we multiply a whole number by a power ofВ 10?ДЄdd on as many 0's as appear in the power.Дoing that is an example of skill in arithmetic, which is to be able to do a problem as quickly and as easily as possible.

How do we multiply a decimal by a power of 10?.

How do we multiply a whole number by a power.

In this Lesson, we will answer the following:
