imFive: Item Model 5

Description Usage Arguments Details Author(s) Examples

This uses item model 5 to create number series items - Identification of co-occurring relationships between elements (with use of arithmetic skills)

1	imFive(arithOne = "add", arithTwo = "substr", n = 2, items = 4)

`arithOne`	Select the arithmetric operator of choice ("add","multi", "sub", "div").
`arithTwo`	Select the arithmetric operator of choice ("add","multi", "sub", "div").
`n`	Value you want use the arithmetic operator on.
`items`	Generate a random mix of items.

Logic analogous to the Item Model 4, but at least one sub-sequence involves the basic arithmetic operations. Sequences combine items from Item Families 1 and 3. The arithmetic operations change but the differences in value remains the name. Example: Odd elements of the sequence increase by 2 and even elements of the sequence are multiplied by 2. (2 12 4 24 6 48 8 (96) (10))
