Coffee Cups and Lesson Plans Again and Again

Hello friends!  I'm back with a little Mid Week Math Motivation, and a game students can play to practice Calculation or Subtracting Fractions.

Hither are the materials you volition demand to play:

Fraction bars:  1 whole, halves, thirds, quarters, sixths, eighths, twelfths, and sixteenths.

(You should take enough pieces to create a whole for each)

Fraction dice with the post-obit numbers: 1/3, 1/4, i/six, i/8, 1/12 and one/xvi

If you don't have fraction dice you tin can cut out address labels to fit your dice and write the numbers on, or find circle stickers.  I found these chalkboard dice at the target dollar spot in the fall, and I used a chalkboard pigment marking to write what I need on them for centers.

If you don't have fraction bars you could go [Hither] and grab a Free set of them, and accept your students color in the pieces dissimilar colors (or print out the colored Freebie), or yous could have your students create a fraction kit using different colors of construction paper.  I use both when we play this game.  The fraction bars that are the freebie I use when we are in course playing the game in small groups.  I accept the cards printed on card stock and I laminate them.  Usually I continue eight sets so that I can have two groups of four playing at the same time.  Some of my smarties need the addition do, while others are ready to move on to subtraction.  I also put magnets on the set up so  students tin can employ them equally manipulatives on our magnetic wall.

I accept my students create the construction paper gear up in class with me.  The pieces are larger, and don't tend to get lost as easily.  We keep the pieces in a ziploc bag then a pocket in our interactive notebooks because I use them for more than than but this game.

It is easiest to begin this game by everyone doing the same thing at the same time.  This manner yous can guide students who are struggling developmentally with understanding the equivalence of the fractions.  I utilize a gradual release concept the twenty-four hour period that I practise this, so my students who gain understanding quickly can go started playing each other.

Adding Fractions Game: Comprehend Upward

Get-go with your 1 whole strip.  Your goal is to comprehend your 1 whole strip completely, without going over.  Take turns rolling the cube and take the fraction you curl and place it on your whole strip.

For example. if I roll a 1/iv, I would take my one/4 strip and identify it over the ane whole strip.  Play continues until the first person completely fills up their strip.  Students are immune to "trade out" their equivalent strips equally they go.  So for case, if a student has a i/4 strip, and so a 1/6, if the educatee rolls a i/3 he/she could merchandise out the one/3 strip for ii-- one/six pieces.  Then they could also see that 3 i/6 pieces can are as large as 1/2, so they tin can merchandise up again.  Here are a few picks of my students trading.  One rolled three ane/12 pieces during his turn.  Once he put them together, he realized he could trade upwardly the 3 1/12 pieces for a one/iv piece.

The whole purpose is getting actually skilful at understanding equivalent fractions.  This is a hands on mode for students to find a mutual denominator.  Once students are comfy with equivalent fraction trading, have them begin to use a dry out erase lath to write a numeric equivalent fraction, and then somewhen an improver equation. If a student rolls the dice and cannot go, he/she loses their turn, and must wait for their turn to curl again.

The winner is the first person to completely embrace their fraction strip exactly.

Subtracting Fractions Game

To practice subtraction, brainstorm with your whole fraction strip covered with two halve pieces.  Take turns rolling the cube, and taking off (subtracting) that fraction.  Y'all volition have to exchange the pieces showtime, then it is a perfect formative way to make sure your students are understanding equivalent fractions (or finding a common denominator).  For example, if I gyre a one/8 on my cube.  I would need to exchange ane of my i/2 pieces for 4/8s in order to subtract one 1/8.  Again, if a student rolls the die and cannot make an exchange, he/she loses their plough, and must look for another turn to curl again. The winner is the offset player to uncover his/her whole slice exactly.

Need to Enrich or Extend?

1) Have students play in pairs and combine their kits and so that have to begin with an improper fraction.

2) Come across who can create the largest covered fraction within 4 turns, or who tin uncover the nigh pieces.

My class really loved playing this game and it was a smashing way for my learners to get a hands on experience with equal fractions, and gain a deeper agreement.

Accept a swell rest of the week my friends!
