## Place Value Basics & Mult./Div.

Last year, I began using Jon Corippo‘s 8 p*ARTS . I saw great success with the repetition. As a result, I thought I’d like to do something along similar lines with Math. Now, I will admit, what I came up with isn’t nearly as fun. However, the repetition is there. This is for 5th grade and can easily be modified for other grades. Here’s what I came up with.

Place Value Basics

The plan:

• Today’s Number – Have the student of the day decide on the day’s number anywhere from billion to thousandths place. However, the number must be at least to the tenths place.
• 10 times greater – Take the original number and make it ten times greater.
• 100 times greater – Take the original number and make it one hundred times greater.
• 1,000 times greater – Yup, take the original number and make it one thousand times greater.
• Add 10 times greater and 100 times greater – add the numbers.
• Write a number that is GREATER – Have students change ONLY a digit that is AFTER the decimal.
• 1/10 times less – Take the original number and make it ten times less.
• 1/100 times less – Take the original number and make it one hundred times less.
• Subtract 1/10 and 1/100 – subtract the numbers.
• Write a number that is LESS – Have students change ONLY a digit that is AFTER the decimal.
• Prime factors of the first 2 digits of the whole number – Only take the numbers in the ones and tens place and find the prime factors.

An example is given on the second slide. This should be done daily, with an assessment each week. The first week or two should be done as a group until the class understands what is expected. Once they ‘get the hang of it’ all that is needed is the number and the students can do this independently.

Update: Since the beginning of the year, I have added a new daily practice paper. Now that they can do the Mult/Div paper well, I switch back and forth. I will soon add a fractions practice paper to the mix.

## Multiplication & Division Basics

In the beginning of the school year, I created Place Value Basics. This was meant as a daily review to get students thinking quickly about some of the basics we learn. It was a big hit! My students went from doing it in 40 minutes (I know, but they needed the time) to around 8 minutes. Pretty good, right!?

Well, they had been bugging me to change it up. THIS is a good sign. So I came up with Multiplication and Division Basics. As some were still having a bit of trouble with Prime Factors, I kept in on this version.

Each year I teach this before Winter Break. Then after this, we head into fractions. Fractions take up all of the 2nd Trimester and by the time 3rd Trimester and the State Test roll around, students have forgotten how to multiply and (deep sigh here) divide. The problem is they have a shaky footing on these concepts before hitting fractions. I know, I’m the teacher… I should go with what they know and base lessons around them. Yes, in an ideal world that is happening. However, the pressure to do Benchmark Assessments and my district’s pacing (don’t get me started on that), and prepping them for the next grade are all too much for me – and them I suspect.

I have seen a great success with my students and the Place Value Basics. I am hoping that they can have the same success with this. How long will it take us in the beginning? Ugh, I hope not the 40 minutes! It’ll take us a while the first week or so, but in time they will successfully complete it in 8 minutes or less! Again, I will start off doing this whole class.
