Online Games for Grades K-1


Counting, Numbers, Ordering

Five Frame Activities and Ten Frame Activities. Students click on the number that tells how many chips arranged are on a five- or ten-frame; use chips to build a given number on a 5- or 10-frame; click on the number that shows how many more circles would fill the 5- or 10-frame; and use 5- or 10-frames to solve addition problems.

Concentration. Players try to match numbers (1-6 or 1-10) and the amounts they represent. The cards can be face-up or face-down. (This game can also be played with shapes and shape names, see Geometry below.)

Whack a Mole. In the basic version, the starting number (0) is displayed at the top of the screen. The player clicks on the number that comes next (1) when they see a mole labeled with that number pop out of a hole. The game can also be set to begin counting from any number up to 100 and so that players have to count by a number, rather than by 1’s. For example, count by 2’s starting with 0. K-1 students will benefit from practice counting by 1 from 0, or from any number (e.g. 12, 37), and may enjoy exploring counting by 2s, 5s, and 10s, from 0.

The Number Track. Players complete a number track that goes to 20 by placing 5 numbers (or 10, or all of them) in the appropriate empty spaces. Students can also design their own game.

Addition and Subtraction

How Many Under the Shell? Players choose a number of shells to play with. The game counts out the shells and then an octopus hides some. The game counts how many are showing, and players use that information to determine how many are hidden.

Save the Whale. Given two labeled pipes of 10, side by side, the player has to complete the partially filled in one (e.g. if it has 6 links, the player needs to drag the one with 4 links up) to save the whale.

Add to 10. The player needs to shoot a ball labeled with a number 1-10. If it hits the number that sums with it to make 10, both balls disappear (i.e. try to shoot the 7 so that it hits a 3).

Flight for Fuel. This videogame-like game provides practice with addition of two or more addends. Players try to collect an exact amount of fuel (e.g. 11) by gathering bits at a time (+4, +3, etc.) without going over.


Concentration. The player tries to find matches between shapes and shape names. The cards can be face-up or face-down. The computer will read the words aloud if requested.


Guess My Button. Students try to figure out which button the computer has chosen by asking yes/no questions. Young students will need help with the reading, with determining the different attributes, and with the logistics of playing (e.g. how to ask a question, how to process the feedback from the computer).


The String of Beads. Students make a copy a given repeating pattern.

Color Patterns. Students finish a partially completed pattern. (Note that some of the patterns might be quite complex for K-1 students.)
