Today the students learned how to use in/out boxes to discover what a rule is for a given set of numbers. Right now they will only have addition and subtraction as a rule. For example if a rule is -5, the in box may be 15, the out box 10, the in box 20, the out box 15, and they have to figure out that they are subtracting 5.
The second math group will have a test on Thursday and the first math group will have a test on Friday. Please review over the properties of addition, fact families, what's my rule, and finding missing numbers.
