How do you do division in openoffice how to#

Students can get confused or frustrated when they donвЂ™t remember the steps, which negatively affects their math confidence and performance.Д¬hallenge students to come up with their own unique way to remember how to do long division - divide, multiply, subtract and bring down- to get the creativity flowing in your classroom. Long division has lots of steps, and they have to be done in the right order to get to the correct answer. Some math books that cover division include: Use them to explain division and remainders to students in a fun and engaging way, and even to cover more basic concepts before they start learning how to do long division. Math booksД«oost literacy and math learning at the same time with fun books covering tricky math concepts. As always, the first student to fill up a whole row, wins!Д¬hallenge your students, but make sure you take enough time with this activity - some students might have trouble solving problems quickly, and can get frustrated or make mistakes if theyвЂ™re not able to keep up. Write the problem on the board, and then give students scratch paper and a chance to solve it and see if they have it on their card. Each of the numbers on a studentвЂ™s sheet should match up to a question that you have at the front of the classroom. This is a good spot to make sure that theyвЂ™re not struggling and that they completely understand the relationship that division has with place value and multiplication.ДЇor a refresher, check out this video from Khan Academy:Д«ingo is a classic for a reason. Remind students that the steps stay exactly the same no matter how big the problem is, and encourage them to use scrap paper to вЂњguess-and-checkвЂќ their multiplication as they go. As they develop confidence and begin to understand how to do long division, start presenting them with problems that have a three-digit dividend, and then problems that have a two-digit divisor.

Let students get comfortable with the formula and work on smaller problems. Have a discussion about why the steps work, and help them understand how place value plays an important role in the process. Remember that this is a totally new concept for students, so take the time to model problems on the board. Start with one-digit divisors and two-digit dividends to keep things simple. Bring downВ the dividend in the ones column and repeat.Multiply the divisor by the quotient in the tens place column.Divide the tens column dividend by the divisor.The steps are more or less the same, except for one new addition: Now itвЂ™s time for students to tackle problems where the divisor doesnвЂ™t fit neatly into the tens orones column. Have them multiply the divisor by the quotient and add the remainder - the answer should be the same as the dividend they started with. This is a good time in the lesson to teach students how to check their answers. Make sure to model several problems as a class so students can begin to understand the steps and how to properly write their answers. The number theyвЂ™re left with is the remainder. SubtractВ the product from the ones column.MultiplyВ the divisor by the quotient in the right place column.DivideВ the ones column dividend by the divisor.But how many times does 5 go into 7, and what do you do with the leftovers? Now, begin with the tens column and work through the problem: 5 goes into 5 exactly once, so thereвЂ™s nothing left there.

ThatвЂ™s where you come in to save the day and explain how to do long division with remainders.ДЇirst, show students a problem that has a remainder in the ones: 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? Ask students how many times 2 fits into 4.
