Virtual Function Machine
Students who've been working on the Function Machine Grade 4 Calendar Grid for February may want to try this on-line version. In the game, the machine gives you the first pair of In/Out numbers. When you push "Get a Number" the machine will give you the next set of numbers. Whenever you're ready to guess the rule, you submit information telling what the machine is doing. If you're correct, the game ends; if you're wrong, play continues and you can attempt additional guesses.
This game could be played at home or at school. Grade 4 and 5 teachers may also want to use the activity as a lesson extension in Unit 7.
