In this game you will practice your knowledge about rounding decimals to the nearest whole numbers. You have to answer each question correctly to get a chance to kick the ball.
To round a decimal to the nearest whole number, look at the digit that indicates the tenth place value. If this digit is greater than or equal to 5, you have to round the decimal up. If that digit is less than 5, you have to round the number down. Erase the decimal point.
Example: 31.78 rounded to the nearest whole number is 32, because 7 is greater than 5, therefore we have to round the number up.
56.2 rounded to the nearest whole number is 56, because 2 is less than 5, therefore we have to round the number down to the nearest whole number.
In this game students will discover that numbers can be written as the sums and differences of other numbers. The game can be played alone, in pairs, or in teams. This game can be played on computers, iPads, and other tablets. You do not need to install an app to play this game on the iPad.
The game is based on the following Common Core Math Standard:
Solve two-step word problems using the four operations. Represent
these problems using equations with a letter standing for the
unknown quantity. Assess the reasonableness of answers using mental
computation and estimation strategies including rounding.
