Count Hoot’s Number Games. Players solve a variety of addition and/or subtraction problems, including unknown change problems (4 + ? = 6 and 6 - ? = 2). Level 1 presents problems with totals to 6 using the dots on ladybugs’ shells and Level 2 uses numerals and totals to 9. Level 3 is involves facts to 20. From the BBC. (This game requires Adobe's Shockwave download.)

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.

Math Lines: 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).

Snakes and Ladders. The traditional game, for 1 player or 2, by the BBC. Players roll a 1-6 die to see how many squares to move. (This game requires

Spooky Sequences. A line of numbered ghosts appears, one without a number label. Players type the number that should be on that ghost.

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.

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.Tangram Puzzles. Students arrange a set of 2-D shapes to form a picture. Young students will do better with sites that provide the outlines of the puzzle they are to solve, rather than just a small picture of the completed puzzle, and may need help learning how to turn shapes to change their orientation. Try Playhouse Puzzles by Invention at Play (3 puzzles), Tangram Puzzles from PBS Cyberchase Games (20 puzzles, be sure to click "lines on"), or Tangrams (14 puzzles, click on the pictures at the bottom of the window).
