This Flash applet is an interactive version of the classic game that develops number sense and strategic thinking. The computer generates a random secret number. The user makes guesses, taking advantage of the higher or lower clues provided, until the number is discovered. The goal is to find the secret number with as few attempts as possible. Three levels allow the user to adjust the range of possible numbers: up to 100, 500, or 1000.

This interactive game gives students practice in counting and ordering numbers. Users try to determine the magician's secret number in as few tries as possible by adjusting their successive guesses according to feedback (too high or too low). Solvers can choose from three ranges of numbers (1 to 10, 1 to 100, or -1000 to 1000) and choose whether or not to view previous guesses.

This interactive Flash applet helps students develop number skills by having them drag clusters of numbers to complete a rectangular grid. Levels vary in content and difficulty, and some feature missing numbers. Skills include counting from 1 to 20, counting from 1 to 100 in several different orientations, and multiplication facts 1-25 and 1-100. A Help screen offers instructions.

Reference Materials
With this interactive Flash applet, intended for use with a projector or interactive white board, teachers can help students understand place value and the structure of our number system. Shapes can be placed on the 100 chart; students use number patterns to determine which numbers are hidden under the shapes. By choosing Hide or Highlight and then selecting specific rows or columns to hide or highlight, the teacher can adjust the challenge level or bring attention to parts of the chart.

This flexible interactive applet helps students develop number sense and fluency as they explore number sequences and patterns. Users can select preset or random number lines, or create their own by entering starting numbers and increments. Colored blocks can be dragged to hide or reveal specific terms in any sequence. Starting numbers and increments may be positive or negative; they may also be decimals. An Ideas page suggests possible uses for this applet.
