## Decimal Dice Game For Grades 4-6

Last year, I was fortunate enough to attend a NCTM (National  Council Teachers of Mathematics) conference in Minneapolis, MN.  One of the booths that was represented was a booth from Box Cars and One- Eyed Jacks.  (Their website is located here)

I bought some of the coolest place value dice.  They were about 50 cents each and you can buy them online also however the shipping is expensive.  I also found them on Amazon located here for decimals and whole numbers. Each of the dice had a particular number on them -see the picture below.

So when I got back home, I tried to think of something to do with these awesome dice.  At the time, we were working on adding and subtracting decimals so I made the worksheet above.  In it, the kids received one each of the tenths, hundredths, and thousandths dice.  Their job was to take turns rolling the dice and then adding them together. Once they got their numbers, they had to compare it to their partners.  A colleague of mine suggested that they could compare their numbers and determine which had the largest decimal therefore hitting not one, but multiple common core standards at the same time.

The kids had so much fun with these dice.  I bought several of the larger place value dice as well.  My next task is to develop some additional games or worksheets for students to write numbers in standard, expanded and word forms with those.

If you would like a copy of the worksheet above that I made, click here and you can print your own copy.  I also have a store at Teachers Pay Teachers that has some more awesome math stuff.

## Order of Operations Task Cards

Order of Operations…..  A procedure that my students need to memorize in order to be successful in algebra and higher secondary math.

These task cards are designed to help my students practice while I work with small groups in the back.  My students can complete the work and then use the iPad to scan the QR codes.  The QR codes link the students to a sheet with my work.  If they make a mistake, they have the answer and all the  work shown to compare and figure out where they went wrong to correct the mistake.  This provides instant feedback from me, even though I am not beside them.  It’s like cloning myself!!!

The only prep and materials that are required are a printer, scissors and some lamination (optional).  I went ahead and  laminated them so that I can reuse these year after year. These task cards have both regular problems and test prep problems.  If you would like to see them or use them  – click here to find them in my store.  I am super excited about using these again with my students next week!

Long Division…..  The thought makes some people cringe in horror or shiver with remembering all of those hours practicing over and over that same method.

In 5th grade, our job is to bridge that gap between concrete understanding in elementary school to the abstract understanding required in junior high.  Traditional algorithms are taught while also still allowing students to choose their method to solve real world problems.  One of the ways I like to practice, is by using task cards.

I have 84 minutes to teach math each day (which is super exciting coming from 45 before) and my students work in a math workshop setting.  Whole group usually lasts about 20 min while students use the rest of the time to rotate through stations.  Since I am teaching a small group in the back of the room, I need stations that are set up to run independently which is why I created these task cards.

These task cards are cut out and printed on card stock.  I then laminate them so I can use them for multiple classes and groups. The students use notebook paper to work out each problem and check their answers.  Students use an iPad to quickly scan the QR code, and it takes them to a photo image which contains the problem worked out on white boards along with the correct answer.  They can then check their answer and if they did something wrong, they can see exactly where they messed up.

I am in the process of designing additional cards to be used for different areas including multiplication and decimals.

This is an example of one of my long division cards. 1/2 of the cards have no remainders, while the other 1/2 of the cards have remainders in which the students have to figure out how to interpret based on the real world scenario that is provided.  Currently, I have cards with 1 and 2 digit divisors, decimal division, multiplication and expressions

If you would like to check out these task cards, I have a free sample version (contains 8 cards) on my teachers pay teachers website – click here  .

The full version of the 1 digit divisor (containing 24 cards) is also on my site that is listed here . and the full version of the 2 digit divisor (containing 24 cards) is listed here.  I would love to hear what you think if you try these out in your classroom or home school.  They are designed for 4th/5th grade but can be used at other grades to enrich or for remediation.

Full version with 24 task cards!

Task card printed in black and white, laminated on color paper.

If color copies are an issue (we don’t have a color copier at our school,)  then you can print the cards out and glue them onto colored paper.  Not nearly as pretty as colored but are effective none the less.

## Place Value Patterns- Multiplying & Dividing by 10

Place Value Patterns- Moving the Numbers!

Part of our curriculum in 5th grade is to recognize that in a multi-digit number, a digit in one place represents 10 times as much as it represents in the place to its right and 1/10 of what it represents in the place to its left.  (Arkansas Mathematics Standards)

Students also need to understand why multiplying or dividing by a power of 10 shifts the value of the digits of a whole number or decimal and explain patterns in the number of zeros of the product when multiplying a whole number by powers of 10.  This is not just for whole numbers but decimals place values up to the thousandths place.

This year we were working with a program called Eureka Math.  They illustrated a great way of moving the numbers back or forth when multiplying and dividing instead of just moving the decimal, which is a quick short cut way that leads to misunderstanding.

So, until the students understood what was happening in actuality to the numbers  in each place value, they had to draw the place value chart or lines to represent the different place holders in the chart.  Once they could explain accurately what was happening to the numbers, most quickly figured out the short cut way of moving the decimal to the right or left.

I created an anchor chart (above) that helps the students to remember the patterns.   This was easy for them to see and we also put a miniature version in our math notebooks.

## Order of Operations- Matching Game

This game is a fun game that reinforces evaluating order of operations with various grouping symbols.  Designed for 5th grade, the game contains 20 problem cards, 20 answers cards. and directions for 3 different ways to play.  Students can choose which game they would like to play or a teacher can vary the game based on needs of students.

May play with 2 – 4 players.  I printed the cards off on card stock and laminated them to make them more durable to use year after year.

It is currently on my store at the following site. A great review for 6th grade and works as a homeschool game, a whole class game or a math center file folder game.

## Free Dice Place Value Game- Designed for 4th and 5th grades.

Place Value and Large Numbers – both give some of my students anxiety at the beginning of the year.   We usually spend a couple of days reviewing previous knowledge of large numbers to the thousands place, while moving that knowledge along to the millions, billions and trillions.

This game was designed for my students to play while in small groups.  The goal is a fun way for them to review and practice reading and comparing large numbers.

In this game, students take turns rolling dice.  Each dice roll, gives the students a number to be placed in one of their empty place value positions.  They can then put this number anywhere they want while also trying to figure out where it would give them the smallest or largest value, depending on the variation of the game.

Included in this game are directions for three different variations; partners competing to see  who builds the largest number, smallest number or reads it correctly.  There is also a score sheet at the end.

In round 1, student each roll the dice 4 times, trading turns between each roll, to build a number to the thousands place. If the teacher tells the students to get the largest number, the student whose number has the largest value will win the round and receive 1 point while their partner earns 0 points.   As an added bonus, I tell my students they must also read their number out loud correctly to their partner.  This helps my students build up their fluency of reading large numbers.

The rounds are designed to increase in difficulty as the game progresses.  In round 1 students are playing to the thousands place, however rounds 4-10 they are playing to the millions place.  My 5th graders loved it this year and it provided a great way to review those place value skills.

This is a free game on my teachers pay teachers store. All you need to do… Add dice!

Perfect for 4th & 5th Grade and that extra challenge to the those 3rd graders who need it! Enjoy!

## Multiplying by 1 Digit- Algorithm Method

-In 5th grade, the Common Core math standard is multiplication by the standard algorithm.

-Some of my students came to me knowing how to do it from their parents or from 4th grade, but most were lost.  In order to combat that problem, I started by problem solving with them repeated addition problems.  I made them long so they could begin to see why we needed something easier and faster.

Once that was established, we made a quick how to guide – and called it the quick start guide. This way if they got lost on any of their steps, they could turn back in their notebook to that page to assist them.

After a couple of days of practicing in whole group, then small groups and then on their own, I gave them an exit slip to see who could do the algorithm and who couldn’t.  For the students who were still having problems, I pulled them aside in small group reteach to work on the skills they were struggling in.

For the other kids, I introduced them to different types of word problems and manipulatives like Versatiles in which the students could continue working on the skills, just at a level above the other students.  Enriching them so they wouldn’t get bored. They loved the manipulatives and called them fun with toys.

By the end of the week, I had 94% of my students who could compete the algorithm completely on their own.  I felt that overall it was a good week.
