## Build, Sketch and Record – Must See Charts!

These charts are great for any grade level (they are flashing underneath the heading Content Standard Posters). First the students build a model of whatever they are studying, then they sketch it and finally they record it with calculations! Simple and Brilliant!  Try it and let me know how it goes!

## Teaching the Area Model for Division

The CCSS Math Practice 5 talks about different tools that students will use to solve problems.  Here is a great digital tool from the National Library of Virtual Manipulatives that helps students to learn and practice division using the area model.

## Bowling to Learn Subtraction: Great Guided Math and Center Activities

Bowling is a great way to teach children subtraction through ten.  Afterall, there are ten pins and when you throw, away they go.  Buy a real play bowling set from Target, Walmart or Kmart and roll away!   You can also make or downlowd bowling subtraction sheets.  And of course, there are virtual versions of bowling to practice subtraction!  I love the internet!

Be sure to have the children talk about what they rolled and what remains. This takes the conversation to the abstract level, especially if you record some of the thinking.  It might sound like this:  “So Maria, you knocked down 3 pins.  How many more pins do you need  to topple all ten?”  That type of question frames it as a 3 + ? = 10  Or, it might sound like this, ” Taylor, you had 10 and bowled away 5, how many are left?”  That type of question frames it as 10-5 =?

After you play this a great deal, you can set up these types of problems in the word problem center and students then have a context for solving these problems.  Remember that concrete, pictorial and then abstract scaffolds mathematical success!

Here are a few links to get you started!

## Fractions on a Numberline: Math Workstation Activity

Fractions on a Numberline is a big CCSS math idea.  Here is a great math workstation activity that brings that to life on a visual numberline.

## Pattern Block Spinners and More: Geometry Math Workstations and Guided Math Lessons

Geometry is the only CCSS Math Domain that spans k-8.  We need to teach it throughout the year.  Have daily and weekly routines where you discuss shapes.  You might have a shape of the week where you discuss a shape deeply, adding to the  discussion everyday.  Here are some great spinners to use in math workstations.  You could have the students spin and collect and graph shapes.  They could also spin and try to fill in pattern block puzzles.  They could also spin and try to compose different shapes for example whoever makes 4 hexagons first, wins.

## More Math Center Websites

Here are some great math center websites!  It says 2nd grade but spans various grade levels. You could get lost on here! BE VERY CAREFUl!  It’s loads of fun standards based activities for the students.

## More Great Math Games

Here is a great site for math games.  I like the interactivity and the fact that they use different models and strategies in the games.  Watch the videos for each game to understand how they work.  For example, in the alligator subtraction game, the students see a fact like 8+9 and then they are encouraged to think 9+9 and take away 1.  They do this by looking inside the alligator’s mouth and then pulling a tooth.  They have a bunch of games that use the open number line as well.  For example, in the Catapult Castle, students have to figure out how many to the next ten and then adjust the target by pulling on a line that moves that many. They also have the beadstring for teaching various number facts.  This is an interactive model for teaching “the dolch words of math” – illustrating facts through 20.  They give you the choice of one or two strings.  Try out the games. Let me know how you are using them.

Sometimes, for a guided math group, I will sit with the students at the computer center and have them play the games and talk about what they are doing.  I can see them use virtual models, question them about the strategies and models they are using and really bring out “the math” in the game.

## Making Math Real

Here is a great math blog to check out.  It has tons of posts about math in the real world, solid resources and some good videos!  Check it out! Peter and Trish make lots of interesting interdisciplinary connections across many different grade levels.  Here are the names of a few of their posts:

Math and International Travel

Teaching Mathematics from a Museum

Math and the Cemetery

Where is Zero on the Earth?

Teaching Slope in the Mountains of Switzerland

There is a little something for everybody.

## Division Strategies and Algorithms: Great Guided Math Lessons

Can you show your thinking about 250/50 in more than one way?  What about your students? Can they discuss this problem with numbers, words and pictures?

Division with Base Ten Blocks

Division with Virtual Manipulatives

More Division with Virtual Manipulatives (I would use real base ten blocks and then show the process with virtual manipulatives).

Area Model

Partial Quotients

Chunking

Short Division (Notice the use of her language?  How could you help describe this process by using language that is descriptive of the actual place of the numbers?)

Be sure to look at all the Schultz videos on different strategies and algorithms for division (scroll all the way down).  Also take a look at the other posts on strategies and algorithms in this series on operations.  I always encourage teachers to do this type of work in small guided math groups so that students can get a chance to explain their thinking and listen to the ideas of others.  Also remember that the new math common core is encouraging us to build a repertoire of strategies and algorithms for the basic operations.  Of course, teach the traditional algorithm as well, but teach it with conceptual understanding as well as procedural fluency!

Happy Mathing,

Dr. Nicki
