Rounding To Nearest 10 Or 100 Math Games

5 games

In this series of games, your students will learn to use place value understanding to round whole numbers to the nearest 10 or 100. The Rounding To Nearest 10 Or 100 learning objective — based on CCSS and state standards — delivers improved student engagement and academic performance in your classroom, as demonstrated by research. This learning objective directly references 3.NBT.A.1 as written in the common core national math standards.

Concepts Covered

Place value in base ten groups numbers in bundles of 10’s with each place value being 10 of the prior unit. While moving to the right across the places in a number the digits represent smaller units. Rounding to the nearest 10 or 100 requires an approximation of the nearest number with no ones or no tens and no ones. Use of a number line to model the closest 10 or 100.

The rule for rounding the nearest 10 is to determine if the one’s unit has a digit that is 4 or below. If so, the one’s digit is rounded to 0 and the tens digit remains the same. If the one’s digit is a 5 or higher then the one’s digit is rounded to a 0 and the tens digit moves up one consecutive number. If rounding a 100’s number to the nearest 10 the hundreds digit remains the same unless the tens digit is a 9 and the one’s digit is 5 or greater. In that scenario, the hundreds digit increases by one consecutive number, and the tens and ones are both rounded to 0.

The rule for rounding to the nearest 100 is to determine if the tens unit has a digit that is 4 or below. If so, the ones and tens are rounded to 0 and the hundreds digit remains the same. If the one’s digit is a 5 or higher then the one’s digit is rounded to a 0 and the hundreds digit moves up one consecutive number. Rounding to the nearest 10 can produce a hundred if the tens place is a 9 and the one’s digit is 5 or
greater.

Image for Influence of the Oceans
Influence of the Oceans Estimated Duration: 5 minutes Why is water colder the deeper you go? In this game, you will learn about convection and conduction with regards to the ocean. You will learn about how the ocean affects temperature and weather. You will observe simulated explanations of thermal energy and the oceans. Make sure you pay close attention. You will be asked questions at the end from the information you learn.
Image for Influence of Oceans on Weather and Climate
Influence of Oceans on Weather and Climate Estimated Duration: 4 minutes The ocean exerts a major influence on weather and climate by absorbing energy from the sun, releasing it over time, and globally redistributing it through ocean currents.
Image for Galaxy Escape
Galaxy Escape Estimated Duration: 20 minutes 10 Bright Monsters have been captured in space and they need your help to cross the galaxy jumping between platforms, finding them, and releasing them by correctly answering each question. Each monster that you release and unlock will be available to play with in the next level, in the search for the next monster. In your journey, you’ll be able to find power-ups, like ‘Double points’ and ‘Slow down’, which can be activated by finding gems, and their duration can be extended by correctly answering a question. Unlock and release the 10 different monsters and a spaceship along 10 different levels, while you make the most possible points.
