Practice rounding through to the nearest hundred thousands place with our set of 36 whole number rounding match-up cards.
When you ask someone their height, hardly ever would they say something like “I’m 5’11 and ¾.” What a mouthful!
No, they’re going to just round up and claim a solid 6 feet.
Why? Because it’s much easier for our brains to work with nice round numbers. Though they aren’t exact, they are close enough. And we’re better able to keep tidy random numbers organized in our minds instead of loosely floating around looking for solid ground!
In our rounding numbers game, students will be rounding up from the tens to the hundred thousands place value. To play, students will find pairs of cards that show the number with the underlined place value rounded correctly. The player with the most matches at the end of the game wins!
Practice Rounding Numbers to the Hundred Thousands Place Value with Our Rounding Numbers Game
This resource is best used in a math center, or in guided practice with your math small group.
Shuffle the cards and lay them facedown in the center area. Taking turns, players will flip two cards, trying to find the pair of unrounded numbers (with the place value that they must round to underlined in blue) with its matching rounded number card. If they match, the player keeps them. If they don’t, the player turns them back over in the same spot, and their turn is over.

Rounding Whole Numbers Group Lesson
Use your smartboard or another projection device to go through the cards as a class. Display the cards with the underlined numbers and ask students to record the rounded number on a separate piece of paper.
This activity is a spin on the classic “Newlywed Game” and works best with small groups because you’ll need enough dry erase boards and markers for each student. Divide the students into 2 groups, and have them sit down in 2 lines facing each other. Show the players a card with the underlined number and ask them to round it up (to the hundreds or thousands place as specified on the card). Students will get 10 seconds to write the corresponding rounded number on their board. On your cue (for example, you say “Ready, Set, Go!”) the students turn their boards around so their partner can see their answer. If both students in a pair have the correct answer, they get 2 points. If one has the correct answer, the team gets 1 point.
Place each of the 18 underlined number cards around the room. Ask students to stand up with their recording sheet and rotate through each of the cards, writing their answers on a separate sheet of paper.
Change the Difficulty Level if Needed
For an added challenge, after matching the cards, have your students put all of the numbers in order from least to greatest.
If you have students who need extra attention, let them build their proficiency by focusing only on using specific place values, going in order from rounding to the nearest tens place to hundred thousands.
