Splat Square is a 100 grid that starts out blank. There are different "splat" colors on the right side of the screen. Choose a color and then click on the square, the number is revealed with a splatter of colored paint (Counting by 2s, 5s, 10s etc)
Math Doodles is a set of interactive math games that encourage students to think/interact with math. Students playi games like Connect the Sums, Number Jump, Polyomino Shift, Double Traits, Sums Stacker, Hydro Maze, Time Shuffle, and Angel Fish (coming soon).
Make 5 is a fun interactive tic-tac-toe type game (it actually reminds me of Connect 4). This game is a great way for students to practice math facts and to recognize relationships between numbers. Students are given a target number, they choose an equation on the grid that equals the target number. The goal of the game is to get 5 squares on the grid in a row in the least number of tries. The game has several play options; students can play the game with one or two players, set up the game to get 5 or 3 in a row, and can play to practice addition, subtraction, or multiplication.
