Number Cruncher
http://www.sciencenetlinks.com/interactives/numbercruncher.html
Description
This Science NetLinks interactive challenges students to consider mathematical equations to get from one number to another in a math maze. Students use a series of addition, subtraction, and multiplication equations to reach their goal. To add an additional challenge to the game, those who solve the problems easily can limit each level to reaching the target in seven or fewer steps.
The activity appears as a 5x5 matrix of numbers, each of which has a symbol next to it, indicating whether it will be added to, subtracted from, or multiplied by the previous number. Students start in the center with a given number and then must choose an adjoining number to complete the next step. They proceed until they have successfully made the goal number or until they have run out of usable numbers on the game board (either by reaching a dead end or by using up all the numbers on the board).
Using the Resource
This resource helps students become more proactive in manipulating series of numbers using mathematical processes and consider the big picture by thinking through several smaller steps before acting. This activity will help students with lessons in logic, decision-making, and task planning as well as make them more confident with their math skills.
The Learn More button offers additional suggestions for math or number games.
