In this online game, students will be building numbers using Base 10 blocks.  Students decide if they want to select ones, tens, or hundreds.  Students also get to choose if they want to read the number, listen to the number, or if they want to count the blocks given and deterine the number being represented.

In this online game, students will practice counting forward from a given number with the known sequence.  Students choose a starting point and then will practice sequencing numbers in a 20 digit range.

In this online game, students will practice counting in sequence from a given number within a hundreds chart.  Students can choose between difficulty levels, which differentiate the number of digits given in the sequence and the number of digits to place within that sequence.

In this online game, students will be given a blank hundreds chart and will be asked to place random numbers into the correct cell within the blank hundreds chart.

Place Value Hockey is a fun educational game for kids to practice place value. There are 2 modes of play and 3 levels of difficulty.

This lesson builds on student understanding of basic two-dimentional shapes having curved and/or straight lines. This is a foundational kindergarten concept and provides experience with concrete and manipulative representation.  Student are asked to explain their thinking and justify their reasoning when sorting.

This is a telling time game that has multiple levels.  It has a practice session that shows the students how to play the game.  Then it begins the game with level 1 which is telling time to the hour.  It goes up 4 levels. Students are asked to choose an analog or digit clock.  They are given a time, and then they are asked to move the clock to show that time.  I would use this game to reinforce what students have already learned about telling time.  It would be good for students who are struggling, or for students that are ready to move to the next level.
