Higher or Lower Decimals Game: Comparing the value of decimals

This math game, "Higher or Lower Decimals," requires students to compare the value of decimals. A decimal card is chosen by one player, and the other players are trying to determine the value of the card by naming a decimal value and then receiving a clue of HIGHER or LOWER from the player who drew the card. The response sheet lists the decimal values that are possible to choose. 

 Player One, who is choosing the decimal card, must understand it's value in relationship to the amount named by the other players in the game. The players who are guessing possible values need to understand the values and be able to compare them in order to apply the clues of "higher or lower" given by Player One.
So you can see that this simple game requires a lot of thinking and comparing of decimal values.

Color Coded Fraction Comparison Chart

This color coded fraction comparison chart would be a valuable resource to a student that has difficulty tracking information across a table.  Using a ruler or two strips of heavy paper vertically to compare the fractions would also be an effective strategy to use this chart.  If you don’t want to copy the chart using colored ink, another idea is to use a strip of lightly colored acetate film to help track across the chart.

 How do you recognize those students that could use this differentiating resource?
Look for students that use their finger to track the information, or use a ruler under the line of information, or seem overwhelmed when reading charts of this type.

I personally have difficulty in tracking information across a page, and through experimenting I have found these adaptations to be of value to me.

Got It: A game that practices recognizing equivalent fractions, decimals and percents.

This is the 6th game in a series that highlights the relationship between fractions, decimals and percents. This particular game practices recognizing equivalent fractions, percents, and decimals.

Instruction Sheet

The Equivalent Reference Card is to be used by the Caller to check the equivalents used by the players.

This game uses a deck of cards from Everyday Math called the "Fraction/Decimal/Percent Deck".  If you don't have that particular deck of cards, you can make your own using the listed amounts in the reference card.  You can make them with blank index cards.

Picture It :A game that creates visual models of fractions, decimals, and percents

Here is the 5th Math Game in a series of games that highlights the relationship between fractions, decimals, and percents. In this game you create visual models of the fraction, demimal, or percent card that you draw from the deck. (Card deck is available from Everyday Math or create your own deck using the amounts that you know your students need more practice creating visual models.)

Since my upcoming workshop in my district will feature 7 games... I only have 2 more to create :)

Percent Give and Take, Fraction/Decimal/Percent Card Deck Game #4,

In 3 previous posts, I shared some games that highlight the relationship between Fractions/Decimals/and Percents.



This is the 4th Game called Percent Give and Take.

To obtain a copy of this game click here. This game focuses on calculating a percentage of an amount of money.  Everyone starts with $5.00 and adds and subtracts the percentage of money that is specified from the card deck .

I like this game because it has a lot of strategy since you can give away your money to any of the players and take money from your choice of players too. That means that I want to selectively give money to a player that has a low amount of money, and take my percentage of money from a player that has a lot of money!  The object of the game is to have the most money at the end of the game when one of the players runs out of money.

The percentage cards used are 50%, 33 1/3 % , 66 2/3%, 25%, 75%, 20%, 40%, 60%, 80%, 16 2/3 %, 12 1/2 %, 37 1/2 %, 62 1/2%, 87 1/2%, 10%, 30%, 70%, and 90%.

The names of the games that I have already shared in November and December are: Value Up Fractions, Talking About Decimals, and Getting To Know You..Fraction, Decimals, and Percent.

What Common Referents Should Students Understand in Order to See the Relationships between Fractions, Decimals, and Percents?

Since I've been creating all of these fraction, decimal, and percent games recently, I began to think about this question:

What basic fractional measures should all students be able to picture in their minds so that they can compare different fractions, decimals, and percents?

Well, I like to think about a measuring cup set to help me answer that question.

If a student can compare and visualize: 1 whole, 3/4,  2/3, ½, 1/3, and ¼ , then they can use this information to compare other quantities.  For example, if I was trying to make sense out of 5/8, I would think:

•4/8 is the same as 1/2

•5/8 is a little more than 4/8 or 1/2

•So 5/8 is a bit more than 1/2 or 50% or .5

•I bet it is about 60% or .6 something (actual = .625 or 62%)

Now... compare 5/8 and .42.  Could you do it?

P.S. This is the perfect reason why you should have your children cooking and measuring with you in the kitchen... building number sense!

Getting To Know You...Fraction, Decimal, and Percent Game

This is the 3rd Game using the Everyday Math Fraction/Decimal/Percent Card Deck. This game would be a great introduction to the study of the number sense idea that all three values represent the same amount.  As you can see on the illustration shown on the game board, all three values of 3/4, .75 and 75% have 75 out of the 100 squares colored in to represent the three amounts.

Why take the class time to play this game?  Many students have difficulty making the connection that the values expressed all represent the same value. By using the same 10 x 10 grid to express all 3 values, that helps the students see the connection too.

Please know that you can also create your own fraction/decimal/percent cards in place of those created and sold by Everyday Math.  I'm just highlighting the Everyday Math product because many teachers already have them, but don't utilize them fully in their classrooms.  I found a great internet site that allows you to create your own cards and will discuss it in a future post.

Fraction/Decimal/Percent Card Game: Value Up Fractions

Here is the second game using the Everyday Math Fraction/Decimal/Percent Card Deck from the series of games in which I am creating the accompaning gameboards, recording sheets or game mats to use with the card deck. It's called "Value Up Fractions." You only use the fraction cards from the deck. On the game board is the I CAN statement: "I AM learning to compare fractions with different numerators and different denominators."

I like this game because you have the option of drawing 2 new cards to replace up to two cards already on the game board to try to fix the order of the cards from the least value to the greatest value.  That's where the STRATEGY and THINKING comes into play.
