## Math Links

The students frequently use the wonderful math websites out there on the internet to help reinforce their learning. I will update this webpage to include the websites the students are using, as I introduce the websites in class. Each website/game will correspond to a math concept that I have addressed in class or will review a concept from a previous year. Click on the title of the game to go to the website. All of the game links open in a new window. If the link doesn't open, check to see if your web browser is blocking pop-ups and click to allow the website to open in a new window. Have fun learning!

Place Value

**Number Top It**- An online version of one of the best Everyday Math games ... this game requires a nuanced understanding of place value, as well as probability and implicit risk/reward analysis. Listen to the directions your first time; you can choose to skip the directions thereafter. (Note: Requires an Adobe Shockwave Plug-In on your computer.)(http://media.emgames.com/emgames/demosite/playdemo.html?activity=M2A050&activitytype=dcr)

**The Place Value Game**- This is a game that is similar to Number Top It. The player must use probability concepts to decide where to place randomly generated numbers within a place value frame. If the student reads the final number out loud, this is also great practice reading numbers.

**Manny's Rumba Base Ten Gam**

**e**- A great game to practice using base ten blocks to create numbers into the hundreds. The player also practices changing numbers, a precursor to finding differences mentally. Students love when Manny high-fives them each time they create the correct number.

Fractions and Decimals

## Telling Time

**Bang the Time**- Read the time in words and then stop the clock when the hands are in the matching position. How many points can you score in ten turns? This game helps you practice time words like "half past" and "quarter past."

http://www.oswego.org/ocsd-web/games/BangOnTime/clockwordres.html

**Stop the Clock**- This game has four levels: easy, medium, hard, and challenge. See if you can set a time record while matching the five digital clocks with the analog clocks. How fast can you go? Start at the easy level and then try the other levels.

Level 1 (http://www.oswego.org/ocsd-web/games/StopTheClock/sthec1.html)

Level 2 (http://www.oswego.org/ocsd-web/games/StopTheClock/sthec2.html)

Level 3 (http://www.oswego.org/ocsd-web/games/StopTheClock/sthec3.html)

Level 4 (http://www.oswego.org/ocsd-web/games/StopTheClock/sthec4.html)

**Time Teller**- Drag the hands of the clock to show the correct time. When you think the clock has the right time, click ok. Try to score a perfect game with 10 out of 10 points. Remember, don't let the hour hand be lazy!

Number Combinations (Number Bonding)

**Number Twins**- One of our favorite games, you can practice combinations of ten, as well as combinations that add to any number from 4-15. Learning the combinations of ten automatically is so important before students can move onto increasingly complex mental math processes. To play, you need to click on pairs of balls that add up to ten (or your other target number.) (Note: Requires an updated Flash plug-in on your computer.)

(http://www.coolmath-games.com/0-number-twins/index.html)

**Math Lines**- Similar to Number Twins, you need to click on pairs of balls that are combinations of ten before the line of balls becomes too long. This game is somewhat more challenging, because it is timed - correct combinations will shrink the line; incorrect combinations will bring the line closer to the hole. (Note: Requires an updated Flash plug-in on your computer.)

(http://www.coolmath-games.com/0-math-lines/index.html)

**Catch Ten**- Help BT Bear (Base Ten Bear) catch ten unit cubes as they fall over a waterfall. When BT rescues ten cubes, he'll toss a long (tens strip) on the shore. How many longs can you make? This game lets the player visualize the combinations of ten.

(http://www.learningbox.com/Base10/CatchTen.html)

**Number Bond Machine**

**s**- Play with the 5, 10, or 100 machine to practice combinations (also called number bonding.) This website also allows you to make your own machine with numbers up to one million. This is clean and simple drill practice - see how high a score you can get. Can you believe that this game was designed by elementary school students?!

(http://www.amblesideprimary.com/ambleweb/mentalmaths/numberbond.html)

**Save the Whale**- Oh no, the whale is stuck in a puddle and needs your help to go back to the sea. Drag the correct pipe section to the broken pipe in order to complete the number bond and set the whale free. The default is combinations of ten, but you can choose the bond from 4-10 on the top of the page.

(http://www.ictgames.com/save_the_whale_v4.html)

**Catapult to Ten**- The King has asked you to knock his old castle down. Use your knowledge of number bonding to ten to help destroy the castle by throwing catapult stones at the castle to jump to the next multiple of ten. Pull down on the stone on the left of the screen to launch the stone. Click "next" in between each stone throw. If the game is too easy, check the "hide jumps" box.

(http://www.ictgames.com/catapultCountOn/index.html)

**Cyber Fact Triangles**- Choose your number range, and then practice your "Fact Power" using these addition and subtraction fact triangles. Click on a corner to reveal the number. After revealing two numbers, can you guess the third number?

(http://www.wmnet.org.uk/custom/files_uploaded/uploaded_resources/846/Triangularcards.swf)

**Ten Frame Game**- This is a great game for students still learning to visual numbers up to ten to build their foundational number sense. Thinking about numbers using ten frames can be a helpful way to learn basic number facts. Their are five different games that you can choose to play with the ten frame. You can even choose to play with circles, bugs, stars, or apples.

Estimation and Rounding

**- Glowla has created this weird machine just for you to play with! Here's the deal: The machine will show you a bunch of numbers. You need to type in an estimate of what those numbers would add up to. Sure, if you had all the time in the world, you could add the numbers together, but that's the hitch-- you only have 60 seconds to give your estimate! The secret to solving this puzzle is to round the numbers before adding them together.**

**Estimation Contraption**http://pbskids.org/cyberchase/games/ballparkestimation/

Ice Ice Maybe - Launch penguins from iceberg to iceberg while quickly solving equations with estimation. Make sure to read all of the directions; this is a somewhat complex game. Play the levels that you know; the fraction and percent levels are probably not "just right" now, but you can start with the addition/subtraction and multiplication/division levels.

Number Sequencing

**The Number Grid Game Beginner**

**The Number Grid Game Intermediate**

**The Number Grid Gam**

**e Advanced**- Try to fill in the missing numbers in the number grid. A move from one number to the next within a row is a change of one; a move from one number to the next within a column is a change of ten. How many number grids can you finish?

(http://mathforum.org/te/exchange/hosted/quincy/Number_Grid_Level_4b.html)

**Behind the Blob**- Choose level three when you begin to play with a hundreds chart. You can choose either option for how you want the squares covered. Your task is to guess the mystery number hiding behind the blob. Have fun!

Function Machines/Algebraic Thinking

**Function Machine Game**- Try to guess the rule for the function machine. You can choose the operation (addition, subtraction, multiplication, etc.,) or you can choose "Random" to let the game choose. However, if you choose random, the machine may use a rule with an operation you don't yet know.

(http://www.amblesideprimary.com/ambleweb/mentalmaths/functionmachines.html)

**Stop That Creature**- Another great math game brought to us by the creative people behind Cyberchase. Uncover the rules for ten function machines in order to destroy Hacker's evil clones. The rules can include addition, subtraction, multiplication, and division.

Mental Math

**Math Connect Four**- The goal is to connect four numbers vertically, horizontally, or diagonally that add up to the target number. Add up the sums mentally to practice your mental math strategies. You can select four different levels depending on the number range (10, 20, 50, 99). This constructive game lets you try again if your first attempt is incorrect.

(http://www.mathslice.com/ol_connect4.php)

**Name That Number**- An online version of the Everyday Math game. You can only use two cards to name a number in this version of the game, which you play against the computer. It's not as thought-provoking as the "live" version when you can try to use as many cards as possible, but still good mental math practice.

(http://media.emgames.com/emgames/demosite/playdemo.html?activity=M2A077&activitytype=dcr)

**Alien Addition**- This game provides practice in the addition of numbers 1-12. Invading spaceships with addition problems move down from the top of the screen towards a laser on the bottom.
