# Laying the Groundwork for Teaching Division, Part3

In Part 1 and Part 2 of *Laying the Groundwork for Teaching Division*, I discussed **ways parents can begin laying the groundwork** for the future teaching of division to their children.

###### Teaching division may seem like a complicated task but using manipulatives makes the skill easy to teach and to acquire.

For our purposes in this post, we will use recycled ice cream sticks. Family members could assist in recycling so that you have a useful amount.

(Another alternative would be to use tongue depressors. Just ask your doctor for a handful next time you have an appointment. If you tell him or her the purpose for your request, you may find yourself with a generous handful free of charge.)

##### Let’s Review Place Value First

Before we continue let’s take a moment to discuss the place value of numbers. This is just for the parents’ information.

The number 2 is a one-digit number which is made up of 2 one’s.

The number 23 is a two-digit number which is made up of 2 tens and 3 ones.

The number 234 is a three-digit number which is made up of 2 hundreds, 3 tens, and 4 ones.

In the number 2, the digit 2 is in the one’s place.

In the number 23, the digit 2 is in the ten’s place.

In the number 234, the digit 2 is in the hundred’s place.

In other words, a 3-digit number has 3 digits, one which represents the hundred’s place, one which represents the ten’s place, and one which represents the one’s place.

In the number 2, there is only one digit. This tells us we have 2 ones.

In the number 23, there are two digits. This tells us we have 2 tens and three ones.

In the number 234, there are three digits. This tells us we have 2 hundreds, 3 tens, and 4 ones.

##### Prepare Your Manipulatives

###### Choose your colors.

Back to our ice cream sticks. **Choose a color** you wish to use to represent the hundred’s place. For our demonstration we will use purple.

Choose another color to represent the ten’s place. For our demonstration we will use red.

Now choose another color to represent the one’s place. For our demonstration we will use yellow.

###### Use markers, paints, crayons, etc., per your color choices

**Use markers, paints, or crayons** **according to your color choice** to dye your assortment of ice cream sticks. If your budget allows, colored ice cream sticks may be purchased inexpensively at various craft stores.

##### Teaching the Skill of Division Using Your Manipulatives

Now that you have your own manipulatives, let’s see how we can use them to continue laying the groundwork for teaching the concepts of division. You will find it much easier than you thought.

###### To represent the number **234**, we will use 2 purple sticks, 3 red sticks, and 4 yellow sticks (per our color choices).

(**To make this task even easier,** you may decide to only use even numbers for all digits, especially if your child/student is very young.)

###### 234/2 = ____

###### The example problem we will be solving is 234 divided by 2.

- Lay the sticks out in proper order to represent the number 234.

###### Explain to your child what the colors represent.

- Explain to your child what the colors represent. Always use the same colors to represent the same
**place value.**

- Tell your child to “pretend” he or she has two friends. The number 234 can represent marbles, cookies, building blocks, or whatever your child likes to play with.

- Tell your child to divide the 234 between his or her two pretend friends equally.

###### Direct them through the process.

Draw attention to the 2 “hundred’s” sticks (purple). Share these two sticks equally. They will place one stick in each pretend friend’s pile.

Then direct them to divide the three “ten’s” sticks (red). They will place one stick in each pretend friend’s pile. But what will they do with the third stick? No, they cannot break it.

Show them that they can solve this by trading the “ten” stick for ten “ones” sticks.

Now show them to place the ten “ones” sticks with the 4 “ones” sticks. How many “one” sticks (yellow) do they have now?

Ask them to divide these 14 “ones” sticks between the two “pretend” friends. 7 “ones” sticks should be placed in each pretend friend’s pile.

###### Explain the answer to the problem.

234 has now been divided into two equal but separate groups. The answer to the problem is the amount in one of the groups.

- So, if we share 234 building blocks equally between two friends, each friend will have 117 blocks.

Therefore, 234 divided by 2 is 117.

This is an example of the division of a three-digit number by a one-digit number.

##### Where to start

**Begin with the division of a one-digit number by a one-digit number, continue with the division of two-digit numbers by a one-digit number, and then the division of three-digit numbers by a one-digit number.**

**Go at your child’s pace.**

Remember this is to be a time of enjoyment. Don’t get stressed if your child struggles at first. Eager learners will pick up on what you are requesting as you continue along.

I do hope these posts have been helpful. Parents can do a tremendous job of helping their children enjoy learning these somewhat difficult tasks.

Just take a few minutes each day to lay the groundwork for division and your child will find this task conquerable.
