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