### Resources to Help Your Child at Home

The following selection of games and activities will help your child to practice some of these skills at home.

#### Addition

• Math Lines In this game, race to pair numbers that add up to a target sum. Before your child plays, review the pairs of numbers that add up to the target sum. You might even look at different ways to make the number using game pieces, marbles, or pennies.
• Addition with Manipulatives Players see and hear an addition problem. They can drag marbles onto a work surface to help them figure out the problem. Play includes five levels of addition, starting with simple 1-digit problems. Players must score 70% or greater to advance levels. Audio directions.

#### Subtraction

• Balloon Pop Subtraction View a subtraction problem and pop balloons to figure out the solution. Three levels of difficulty available as well as audio directions.
• How Many Under the Shell? Determine how many bubbles are left under the shell after Otka hides them. Choose addition, subtraction, or both. (Flash)
• Clear It Addition Create number sentences that add up to the target numbers provided. Earn stars for extra points and clear the board before the timer runs out.

#### Measurement

• Inches to Feet  Students match measurements in inches to their equivalent in inches and feet. This game involves mental computation that might be challenging for some. (Flash)
• Measurement Game: Centimeters View a red line next to a centimeter ruler and select the correct answer from four options.

#### Money

• Coin Box  Learn how to count, collect, exchange, and make change for coins. The coin tiles help you count as you learn the value of each coin.
• Learn to Count Money  Players count money by moving coins and bills into a box. The game becomes progressively more difficult as students master levels. Level 1, count to 99 cents. Level 2, count to \$10. Level 3, count to \$100. Also choose from beginner level (using any combination of coins) and expert levels (using least number of bills and coins.)

#### Geometry

• Concentration Click on the shape mode to play a game in which you match each shape with its name.
• Geoboard AppWith this virtual geoboard, students stretch bands around pegs to make discoveries about shapes. iPad and online versions available.

#### Fractions

• Mathman Fractions View a dot on a number line, determine the fraction, then eat the ghost with that fraction to earn points. (Flash)
