Week 2

Division

Number Bonds Division

This is when you have a large number and you put it in expanded form or friendlier numbers. Then you divide these expanded values by the value you are dividing by. For example 4,816/4. You can have 4,000+800+16/4= 1,000+200+4=1,204

Long Division

This is where you try to take out the easier numbers of the large value until you get rid of all of the large number. You may have remainders and that is when you get to a small number that cannot go into the value you are dividing by.

Area Model

You would draw the same box for a normal area model problem but this time you put the smaller number given on the side and then work up to getting the larger number.

Multiplication

Expanded Form

This is when you have a large number. Instead of writing something like 356,728 you would put, 300,000+50,000+6,000+700+20+8

Ratio Table

You can make a table and gradually multiply the larger values together. Then you can put one of the values in expanded form and are able to add them up.

Area Model

You draw a box and put one of the values on a side and the other value on another side. Then you divide the box into friendlier values to multiply.

Partial Products

When you have two values that are harder to multiply together and you stack them and them.
