need serious help with dividing decimals

Anyone in the Proteacher community that has a easy method for teaching dividing decimals, I could sure use it. I have been working with my students for 4 weeks now and every time I assess their mastery my class average is well below 50%. I'm at a loss. This is a state standard that they must know how to do for the state test.

Are they all having trouble with just dividing, or moving the decimal? Or a mixture?

It is a mixture of not knowing how to do long division and multiplication and making mistakes like forgetting to put the decimal in the product or quotient.

Hmmm, are they making similar mistakes with just regular division problems with no decimals? Are they lacking the basics needed in order to do division with decimals? Maybe back-track and do simple division problems and slowly introduce decimals.???

You are going to have to decide on what is important here. If learning to multiply is important, then master that and use a calculator to divide. If learning to divide is important, then give them a multiplication chart and a step by step guide on division. I use Does McDonald's Sell Cheese Burgers to teach the steps in long division. Asking students to master multiple processes at one time is a recipe for failure. It's more work on your part, I'm afraid, but you will in time see results.

trishgirl... what does Cheese stand for?

PS. I agree, go back and do a little re-teaching. I have only been in school a few weeks and am no where near ready to tackle long division with decimals... maybe long division.

Does= divide
McDonald's= multiply
sell= subtract
Cheese= compare
burgers= bring down

Since stopping on "cheese" is a little awkward, it makes them stop and think...is my remainder smaller than my dividend? Are there any more digits in the dividend?

Cheese - Compare. Got it.

I always teach: Every Monster Sucks BlooD
E= Estimate
M= Multiply
S= Subtract
BD= Bring down

But I LIKE the "compare" step!! I wonder
Every Monster Sucks CREEPY BlooD? Hee hee...

My Division Family

I haven't come close to decimal division yet either. We are still working on just long division... especially with 2 digit divisors.

I teach division using a division family.

Dad = Divide
Mom = Multiply
Sister = Subtract
Brother = Bring Down
Rover (the dog) = Repeat or Remainder

But I like the idea of Checking too! I might have to add in Chester (the cat).

This always works for my kids. They always remember the saying also. I still have kids that come back to me saying the saying helped in other grades.
