String of BeadsInvestigations Recommended for Grades: K, 1Use the string of beads to copy colour sequence patterns.

Colors PatternsInvestigations Recommended for Grades: K, 1, 2, 3Students finish a partially completed pattern. (Note that some of the patterns might be quite complex for K-1 students.)
|
Function MachineInvestigations Recommended for Grades: 2, 3, 4, 5Students have to guess the rule the machine is using to change numbers as they pass through it. The machine collects data about the numbers that have gone into and out of the machine. They guess the rule by entering the operation and the number (e.g. x 10 would mean the machine multiples every number that goes through it by 10). (From PBS's Cyberchase Games.)

Mental MathsInvestigations Recommended for Grades: 4, 5Drag a number into the machine, see what happens to it, and use that information to guess the rule. Students guess the rule by entering the operation and the number (e.g. ÷ 3 would mean the machine divides every number that goes through it by 3). Students can experiment as long as they like before making a guess.
