Geometry Center Activities

Geometry is one of my favorite units to teach! Maybe it is because I like to quilt so the patterns and shapes are fun for me! Maybe it is because there are so many hands on activities for my students!  Some of my favorite activities for centers and/or workstations (math workshop) are:

1.  Tangrams:

I love to give my students tangrams and let them explore spatial relationships while building patterns and recreating patterns from books like “Grandfather Tang” and “Tangramables”. If you are lucky enough to have plastic sets of tangrams you can set them up in a center with the books and let your children explore with the shapes. If you need to make your own tangrams, you can download a free pattern here. Print on card stock and cut out. You can also find some cute cards for using tangrams here.

 2.  Make 3D Shapes:

Or … If you prefer paper shapes, Math Geek Mama has Free Printables to make your own shapes!

 3.  Geometry Scavenger Hunt:

Kids need to get out of their seat and move around! One of your best centers can be the scavenger hunt. Place questions around the room and give your students a record sheet to use while they work.  For directions to make your own, see this post:  Making A Scavenger Hunt.  Or to use premade, print and go resources click here: Scavenger Hunt 1, or here  Scavenger Hunt 2.

 

4. Task Cards:

These task cards are great for starting higher level discussions with your students.  Students work together to answer questions identifying, comparing and analyzing critical attributes of 2 and 3 d shapes.

5. Technology: 

Hopefully you have a few computers in your classroom you can use for a station. Here are two good websites for Geometry:

Why & How to Use Task Cards in The Classroom

Why?

Task Cards Save Paper: Using task cards can cut down on the number of copies and paper used because you don’t need to make a set for each student and if laminated or kept in protective sleeves, they can be used for years without printing new copies. 

Task Cards Increase Engagement: They add to student engagement because they add novelty. Paper and pencil practice is certainly useful, but can become dull and routine.  Using dry erase markers on a task card can mix things up a bit.  Also, task cards can be printed with fun colors and clip art to add interest for the students.

How? 

Centers and or Work Stations – Print cards and keep in small containers or baggies.  Have students work in pairs or groups solving problems on task cards and recording on a record sheet.  I like using record sheets for two reasons. One, the students are more likely to stay on task if they know they will have to turn something in at the end of the center. And, the other reason, I like to look over the record sheets to see if students need re-teaching or extra help with the skill/concept worked on in the center.  If you do not have a lot of copy paper you can always have students use notebook paper to create a record sheet.  Have them write the name of the center on the paper and then number or letter their answers.

Whole Class Cooperative Groups – My suggestions for whole class would be the same as for work stations & centers except you would need one set of task cards for each table group.  After learning or reviewing a concept with whole class, the students could work on the cards with their table groups.   After the group work you could have a class discussion about the task cards as a way to wrap up. Another whole class activity which would require only one set of task cards is a “Scoot” or circuit.  To set up a Scoot you have a different task card on each desk and have the students work in pairs rotating around the set of task cards in numerical or alphabetical offer.  Some teachers will set a timer for scoot and others will let students move as they finish.  For a FREE  “Scoot Record Sheet” that can be used with any set of task cards, click here.

Understanding Multiplication and Division in Word Problems

So, the fun and games of learning how to make arrays, skip counting on number lines and using models to solve multiplication problems has lead to the equally exciting task of solving division problems. Everyone seems to be making great progress and making meaning of multiplication and division in real world problems, UNTIL … wait for it … wait for it … We mix the two together!

multiplication-and-division-free

And here the real “fun” begins … A few students usually have an intuition about the structure of the problems and just “get it” with out much help, but the majority of students need direct, systematic instruction paired with hands on or pictorial examples to really, truly, deeply, understand the difference between multiplication and division in word problems.  But where can we start?

Top 5 Tips for Decomposing Fractions

As I have mentioned in previous posts about fractions, starting with hands on and pictorial activities is vital for helping primary intermediate level students understand fractions. Today I would like to share my top 5 tips for decomposing fractions. These are mainly focused on 3rd – 5th grade, but may be helpful for some older and younger students as well.

fraction-decompose-tips

1.)  I love using my pizza game for hands on fractions!  If you don’t have a pizza game, you can use plastic fraction circles or make pizza fractions from paper plates. Show your students a fraction of a pizza such as 5/6. After guided them to name the fraction, show them one way to decompose it by giving 2/6 to one student and 3/6 to another student. Point out that 2/6 + 3/6 is a way to decompose 5/6 and ask if they can name any other ways.  Act out other representations such as 2/6 + 1/6 + 2/6 by giving those slices to other students.  Try this with several different students.

2.)  Give students color tiles or unifix cubes. Give specific directions such as make a rectangle with 3 red, 2 blue and 7 yellow.  What fraction of your tiles are not yellow? (5/12)  Move the red and blue apart a little to show how 5/12 can also be represented as 3/12 + 2/12.  Do this with a few other fractions as well.

3.) Give students pictures of fractions and have them cut them up to show ways to decompose the fraction.

4.) Coloring Practice – Give students pictures of fractions with nothing shaded.  Give them directions on what color to color different parts.  Then guide them to write number sentences to decompose the fractions.

5.) Play Games!  Make your own games to practice decomposing fractions or try one of the games I have available on my TpT page.

Using Place Value to Understand Addition

IMG_20151007_223726

Adding two digit numbers can seem like an easy enough task to those of us who have been doing it for a long time!  But for elementary students it can sometimes be confusing, especially if there is regrouping involved.

It is helpful to most students to start with something concrete, like place value blocks. Before I teach students the Continue reading

Getting Real With Math – Part 2 of 2 (Out and About)

Yesterday I wrote about making math real for children at home.   Connecting Math to everyday life helps children be successful in school by showing them Math is important, building vocabulary and math fluency, and promoting critical thinking and problem solving skills.  If you missed yesterday’s post: Getting Real With Math – Part 1 of 2 (@ home) click here to check it out.   Today I am going to add onto yesterday by pointing out ways to make Math connections outside of the house.  Just like yesterday, I would suggest that you keep it real by discussing problems with your child, give them time to think, reflect, talk it out and try to come up with solutions in a way that is natural and does not feel forced or too much like a “lesson”.

Math at the grocery store:

The grocery store is a great place to use math. Weighing produce, counting soup cans, and comparing prices of  cereals are ways to use math skills and expose younger children to math and numbers. As your children get older you can increase the difficulty of your math conversations. My kids and I used to make a game out of estimating our total as we grocery shopped. This helped with rounding and mental math. When we got to the checkout we would see who was closest to the actual total.  We haven’t actually played the estimating game lately, but they are older now and really good at comparing prices and figuring out an estimate for a total when we are shopping (especially when they are spending their own money).

You can also promote problem solving skills by asking questions such as:

  • If these apples are $1 per pound, how much would 3 pounds cost?   How did you figure that out?
  • These potatoes are $4 for a 5 pound bag.   How much is the cost per pound?
  • If I use this coupon, what is my final price going to be?
  • Which package is a better deal?   How can you tell?
  • How many packages do we need to buy to make sure we have enough toilet paper for the week?

Beyond the grocery store:

Once you start thinking of connecting math to your child’s world you will probably find all sorts of teachable math moments as you are out and about.   Here are a few ideas:

  • Comparing a value meal to buying items a la carte at fast food places.
  • Finding total cost of an outing to a water park or movie.
  • Elapsed time: keep track of start and end time and figure out time spent somewhere.
  • Calculating distance traveled on a trip (out of town or just running an errand).
  • Shopping for clothing, toys, books, etc.
I hope you enjoyed my post.   Please feel free to leave comments with more ideas for using math out and about.
