This flexible, interactive Flash applet allows students to explore number patterns and to develop number sense and fluency with addition, subtraction, and multiplication. The student or teacher enters a starting number and a step increment. Both values may be up to 4 digits and either positive or negative. The user then mentally carries out the sequence and enters the resulting 10th and 11th terms. The first 9 terms are color-coded in groups of 3 and may be shown or hidden one group at a time. Users have the option of hiding or showing the starting number and/or the increment.

This math app intended for upper elementary students using the addition and subtraction level and middle school students using all four operations helps players practice their order of operations. This interactive game encourages students to use higher order thinking to use the five numbers and given operations to solve the "target" number by working backwards given the answer but not the equation. The best feature about this math game is that teachers are able to receive immediate feedback of their studentsâ€™ progress through email. Students do not have to provide an email address in order to play.
